Irregular Modern Greek Verbs

This page is part of a more general, learner-oriented page on Greek verbs (modern and ancient), which in turn is part of the author’s pages on the grammar of the Greek language.

As mentioned in the general information on Greek verbs, each Greek verb comes in two flavors, which we called vanilla and strawberry, which become three if we count the passive chocolate as a separate flavor. (Please visit the previous link and read the beginning of that page to see the justification for this choice of words.) In a brief introductory paragraph on irregular verbs we saw that there are three verbs (βλέπω = I see, λέω = I say, and τρώω = I eat) that have totally unrelated vanilla and strawberry flavors (είδα = I saw, είπα = I said, and έφαγα = I ate). All other irregular verbs have flavors of vanilla and strawberry (and chocolate in the passive voice) that are more-or-less related to each other (they have at least some common consonants) but they are irregular because they cannot be pigeonholed into one of the regular patterns (see the page on regular Greek verbs for a list of those patterns).

The verbs listed in this page are by no means all of the irregular verbs in Greek. However, they are taken from the list of the 1000 most common Greek words (for information on how this list was obtained, see this footnote), so in a way they are the irregular Greek verbs a learner would want to look at for most practical purposes.

Verbs in their main tables are listed in this page by frequency of occurrence in the language, in reverse order (high frequencies first). A list (“Table of Contents”) is given immediately below, for ease of locating a given verb alphabetically.

Finally note that a characteristic of Greek verbs is that often prepositions can be prepended to a base verb, changing completely its meaning. Prepositional forms are listed under the tables of the main verb entry, in a note; but because they are too many, they have been omitted from the Table of Contents, below; so it is recommended that the reader use the search function of their browser to locate verbs in this page. Often the compound prepositional verb is more common than its base form; in that case, the prepositional form is shown as a main entry, and the base together with all other prepositional verbs follow in a note.

Note: The entire conjugation of this verb (all persons) is given here.

Note 1: There is no vanilla vs. strawberry distinction in verb έχω. As a result, the imperfect is identical with the past form: only the context can differentiate whether είχα is meant in the progressive or instantaneous sense.

Note 2: Since the forms of this verb are only two (έχω and είχα), its entire conjugation can be given here, in all three persons and two numbers, thus: present: έχω, έχεις, έχει, έχουμε, έχετε, έχουν/έχουνε; and imperfect/past: είχα, είχες, είχε, είχαμε, είχατε, είχαν/είχανε. The last ε in the 3rd person plural is called a “euphonic epsilon”, and is used to make the speech continuous, usually when the next word starts with a consonant which is not one of κ, π, τ, ξ, ψ; but it is not mandatory. (The euphonic epsilon applies not only to έχω but to all verbs in the 3rd person plural.)

Note 3: There are several compound prepositional verbs formed with έχω, some of which have been regularized. But note that although έχω itself lacks separate subjunctive and passive forms (e.g., there is no “έχομαι”), some of the compound verbs do have their own subjunctive (e.g., παράσχω) and passive (e.g., παρέχομαι). Wherever such forms exist, they are noted below (in parentheses: imperfect, subjunctive, past, passive present):
ανέχομαι (ανά + έχομαι): put up with, tolerate, bear (ανεχόμουν, ανεχθώ/ανεχτώ, ανέχθηκα/ανέχτηκα)
αντέχω (αντί + έχω): endure, stand, bear (listed as regular) (άντεχα, αντέξω, άντεξα, αντέχομαι)
απέχω (από + έχω): abstain, refrain, keep away from (απείχα, απέσχω, απείχα, --)
εξέχω (εξ + έχω): protrude, stand out; be prominent (εξείχα, εξέχω, εξείχα, --)
επέχω (επί + έχω): stand for (as a substitute for smth. else) (επείχα, επέχω, επείχα, --)
κατέχω (κατά + έχω): know (= “γνωρίζω”); occupy (κατείχα/κάτεχα, κατέχω, κατείχα, κατέχομαι)
μετέχω (μετά + έχω): participate (= “συμμετέχω”, see below) (μετείχα, μετάσχω, μετείχα, --)
παρέχω (παρά + έχω): provide (παρείχα, παράσχω, παρείχα, παρέχομαι)
περιέχω (περί + έχω): contain (περιείχα, περιέξω, περιείχα, περιέχομαι)
προέχω (προ + έχω): be of utmost importance, be prominent (προείχα, προέχω, προείχα, --)
προσέχω (προς + έχω): pay attention to, be attentive, watch, keep an eye on (listed as regular) (πρόσεχα, προσέξω, πρόσεξα, προσέχομαι)
συμμετέχω (συν + μετά + έχω) participate (συμμετείχα, συμμετάσχω, συμμετείχα, --)
συμπεριέχω (συν + περί + έχω): include (= “συμπεριλαμβάνω”) (συμπεριείχα, συμπεριέχω, συμπεριείχα, συμπεριέχομαι)
υπερέχω (υπέρ + έχω): be superior (υπερείχα, υπερέχω, υπερείχα, --)
υπέχω (υπό + έχω): be compelled, be obliged (to do smth.); stand for (= “επέχω”) (υπείχα, υπέχω, υπείχα, --)

Note: The middle voice does not make much sense for the verb above. However, πάρσου (middle imperative) is possible, though extremely rare.

Note 1: The middle voice of the verb above has a different meaning than its active and passive senses, and is formed by the vanilla stem. The passive voice occurs almost always in the 3rd person, due to the concept it describes (ειπώθηκε = “it was said”, θα ειπωθεί = “it will be said”, etc.). The passive present and imperfect of this sense are also formed by the stem -λεγ- (λέγεται = “it is said”, λεγόταν = “it was being said/used to be said”, etc.).

Note 2: There is a compound verb derived from λέω by prepending the adverb πάρα (very):
παραλέω (πάρα + λέω): exaggerate, speak by magnifying events thus making them not true (παραέλεγα, παραπώ, παραείπα)
This verb is used almost exclusively in the expression “τα παραλέω” (e.g.: “Μην τα παραλές!” = “Don’t be exaggerating [the facts]!”)
There are also a few compounds with prepositions, but note that they use the regularized strawberry stem -λεξ-:
αντιλέγω (αντί + λέγω): argue against (usu. against authority) (αντέλεγα, αντιλέξω, αντέλεξα)
διαλέγω (διά + λέγω): choose (διάλεγα, διαλέξω, διάλεξα)
εκλέγω (εκ + λέγω): elect (εξέλεγα, εκλέξω, εξέλεξα)
επιλέγω (επί + λέγω): select, cull (επέλεγα, επιλέξω, επέλεξα)
προλέγω (προ + λέγω): foretell (προέλεγα, προλέξω, προέλεξα)

Note 3: The active vanilla stem -λε- is more common (in speech & writing) than -λεγ-; thus, it is more common to hear or read λέω, rather than λέγω (and also in the other persons: λες, λέει, λέμε, λέτε, λέν/λένε, rather than λέγεις, λέγει, λέγουμε, λέγετε, λέγουν/λέγουνε). It should be noted that -λε- is a result of erosion of -λεγ-, which is the original (ancient) stem. In the imperfect and imperative, however, no erosion is observed (no *έλεα, or *λέε!). Also, none of the compounds (see note 2) uses the stem -λε-.

Note: The older form δίδω of this verb (from ancient δίδωμι) works as a prepositional verb constructor (in parentheses: imperfect, subjunctive, past):
αποδίδω (από + δίδω): render (e.g., a translation); confer, bestow (e.g., honors to someone) (απέδιδα, αποδόσω, απέδωσα)
διαδίδω (διά + δίδω): spread rumors (διέδιδα, διαδόσω, διέδωσα)
εκδίδω (εκ + δίδω): publish; push into prostitution (esp. in middle voice: εκδίδομαι) (εξέδιδα, εκδόσω, εξέδωσα)
καταδίδω (κατά + δίδω): betray (pass on information against someone) (κατέδιδα, καταδόσω, κατέδωσα)
μεταδίδω, and μεταδίνω (μετά + δίδω/δίνω): transmit (programme through airwaves); transmit (disease), infect (μετέδιδα, μεταδόσω, μετέδωσα)
παραδίδω, and παραδίνω (παρά + δίδω/δίνω): teach lessons (in class or to student(s)); surrender (esp. in middle voice) (παρέδιδα, παραδόσω, παρέδωσα)
προδίδω, and προδίνω (προ + δίδω/δίνω): betray (a secret); be unloyal/unfaithful (in love) (προέδιδα/πρόδινα, προδόσω, πρόδωσα)
προσδίδω (προς + δίδω): add on (a feature/property to existent/known set of features) (προσέδιδα, προσδόσω, προσέδωσα)

Note 1: the stem -καμν- is non-standard, used in some Greek localities only (mainly in Macedonia). However, in the imperfect it is heard occasionally among other native speakers too, because it distinguishes between the imperfect and past tenses. This verb derives from ancient κάμνω, meaning “I tire/am getting tired”, from which also nouns such as κάματος (toil), and καμώματα (peculiar/unexpected deeds/behavior) are derived.

Note 2: This verb works as a prepositional verb constructor, with one preposition only (in parentheses: imperfect, subjunctive, past):
αποκάνω or αποκάμνω (από + κάνω/κάμνω): resign due to tiredness (απόκανα/απόκαμνα, αποκάμω, απόκαμα)

Note 3: There is a compound verb derived from κάνω by prepending the adverb πάρα (very):
παρακάνω (πάρα + κάνω): overdo (παράκανα, παρακάνω, παράκανα)

Note: The past participle of the above verb does not have the sense “wanted”, as in “a criminal is wanted” (that sense is expressed by “καταζητείται”); instead, the sense of it is “desired”.

Note 1: To express the meaning of the middle voice (“I see myself”), another verb is used: κοιτάζομαι (from active κοιτάζω = I look at), the middle imperative of which is: κοιτάξου! (=look at yourself!)

Note 2: The above verb serves as a prepositional verb constructor (in parentheses: imperfect, subjunctive, past) (notice that the prepositional verbs use mostly the regular, rather than the irregular stems):
αποβλέπω (από + βλέπω): intend, aim; act in expectation of a favorable outcome (απέβλεπα, αποβλέψω, απέβλεψα)
διαβλέπω (διά + βλέπω): see through time and predict a future event by extrapolating from current events (διέβλεπα, διαβλέψω, διέβλεψα/διείδα)
επιβλέπω (επί + βλέπω): supervise (επέβλεπα, επιβλέψω, επέβλεψα)
παραβλέπω (παρά + βλέπω): fail to see by negligence (παρέβλεπα, παραβλέψω, παρέβλεψα)
προβλέπω (προ + βλέπω): predict (πρόβλεπα/προέβλεπα, προβλέψω, πρόβλεψα/προέβλεψα)
προσβλέπω (προς + βλέπω): expect/hope a favorable outcome (προσέβλεπα/πρόσβλεπα, προσβλέψω, προσέβλεψα/πρόσβλεψα)

Note 1: Only the present tense has the alternative form πάω (declined as: πάω, πας, πάει, πάμε, πάτε, πάνε). None of the other vanilla forms becomes “contaminated” with the strawberry flavor.

Note 2: the present tense form “πάω να...” very rarely can denote future (“I am going to [do smth]”). One example would be, “πάει να τα καταφέρει” (“he/she is [almost] going to make it”). But such examples are hard to find. Do not use “πάω να” as a substitute for “I will” in Greek; instead, this verb almost always implies motion from one location to another.

Note 3: Although “πάε!” is given as the simple imperative form above, complying with the strawberry flavor, in practice the command “go!” is expressed almost always by progressive (vanilla) imperative “πήγαινε!”, probably because “going” is conceptualized as a progressive act.

Note 1: The verb above has an alternative form: φέρω in the active present (έφερα, active imperfect), which is less colloquial, making its vanilla stem identical to its strawberry. In this, rather learned form, φέρω usually has the sense “I bear, I have on myself”. E.g.: η ελληνική σημαία φέρει σταυρό (“the Greek flag bears a cross”), or: φέρει ουλή στο πρόσωπο (“bears a scar on the face”).

Note 2: The middle form φέρομαι is produced from this alternative form, φέρω (see note 1), and has a completely different meaning (“I behave”), which is much more common as a concept than the passive one (“I am brought”). Thus, a form such as φέρθηκα means, in most cases, “I behaved”. E.g.: μου φέρθηκε άσχημα (“he/she behaved badly to me / dealt with me badly”). However, the presence of the consonant ν in the stem usually signifies passive voice, e.g.: η φλόγα φέρνεται από την Ολυμπία (“the flame is brought from Olympia”). The meaning of “behave” can also be rendered through συμπεριφέρομαι, which is conjugated exactly as φέρομαι, prepending the prepositions συν- & περι- (resulting in συμπερι-) to all its forms.

Note 3: The form φέρω (and its middle φέρομαι) is prolific as a prepositional verb constructor (in parentheses: imperfect, subjunctive, past):
αναφέρω (ανά + φέρω): mention, report (to be encountered) (ανέφερα/ανάφερα, αναφέρω, ανέφερα/ανάφερα)
αναφέρομαι (ανά + φέρομαι): refer (αναφερόμουν, αναφερθώ, αναφέρθηκα)
αποφέρω (από + φέρω): yield, produce (απέφερα, αποφέρω, απέφερα)
διαφέρω (διά + φέρω): differ (διέφερα, διαφέρω, διέφερα)
εισφέρω (εις + φέρω), and more commonly, συνεισφέρω (συν + εις + φέρω): contribute (συνεισέφερα, συνεισφέρω, συνεισέφερα)
εκφέρω (εκ + φέρω): utter (εξέφερα, εκφέρω, εξέφερα)
επιφέρω (επί + φέρω): cause, bring about (επέφερα, επιφέρω, επέφερα)
καταφέρω (κατά + φέρω): deal (a strike), hit (κατέφερα, καταφέρω, κατάφερα)
καταφέρνω (κατά + φέρνω): manage to do smth. (κατάφερνα, καταφέρω, κατάφερα)
μεταφέρω (μετά + φέρω): transfer, move; carry (μετάφερνα/μετέφερα, μεταφέρω, μετάφερα/μετέφερα)
παραφέρομαι (παρά + φέρομαι): lose one’s temper, go mad/berserk (παραφερόμουν, παραφερθώ, παραφέρθηκα)
περιφέρω (περί + φέρω): carry around (περιέφερνα, περιφέρω, περιέφερα)
περιφέρομαι (περί + φέρομαι): wander (περιφερόμουν, περιφερθώ, περιφέρθηκα)
προφέρω (προ + φέρω): pronounce (πρόφερα/προέφερα, προφέρω, πρόφερα/προέφερα)
προσφέρω (προς + φέρω): offer, proffer; give for sale (πρόσφερα/προσέφερα, προσφέρω, πρόσφερα/προσέφερα)
συμφέρω (συν + φέρω), usu. in 3rd person συμφέρει: be to one’s interests, be advantageous, suit one’s purpose (συνέφερα, συμφέρω, συνέφερα)
συμπεριφέρομαι (συν + περί + φέρομαι): behave (συμπεριφερόμουν, συμπεριφερθώ, συμπεριφέρθηκα)
υποφέρω (υπό + φέρω): suffer; put up with (υπόφερα/υπέφερα, υποφέρω, υπόφερα/υπέφερα)

Etymology Note (based on note 3): It is not a coincidence that the above verbs refer, differ, transfer, offer, and suffer all have a common ending; they are all derivatives of Latin ferre, which is akin to Greek φέρω.

Note 1: This verb lacks not only passive and middle voice, but also the entire strawberry flavor. It is found almost always in the 3rd person: αφορά (present) and αφορούσε (imperfect), as in “ο νέος ιός αφορά τους υπολογιστές εκείνους που...” (“the new virus is about [affects] those computers that...”), or: “η είδηση αφορούσε όλους όσοι...” (“the news concerned [was about] all those who...”). Or, consider these examples in the plural: “τα νέα αφορούν τις χώρες της Ευρώπης” (“the news concern [are about] the countries of Europe”), or: “δεν αφορούσαν εμένα” (“they were not about me”).

Note 2: There are some very common stock phrases using this verb that explain its high frequency of occurrence: 1. “όσον αφορά τον/την/το (or στον/στην/στο - see note 3)...”, meaning “regarding the...”, and 2. “δεν σε αφορά!”, meaning “it’s none of your business!” (lit.: “it does not concern you!”)

Note 3: There has been some discussion regarding whether τον/την/το or στον/στην/στο should follow αφορά. Grammarians have insisted that the correct syntax is αφορά στον/στην/στο, and that people who use τον/την/το do so erroneously. This suggestion for correction has been around since the early 80’s. Nonetheless, a search on the internet reveals that people overwhelmingly use the τον/την/το forms of the article (83%), rather than στον/στην/στο (17%), following this verb.

Note 1: The strawberry flavor of this verb has almost always the meaning “signal”, not “mean”, because the latter cannot be conceived of in an instantaneous sense in Greek: if something σημαίνει (“means”), it “means” continuously. In contrast, in English the form “I am meaning” sounds rather peculiar, if not plain wrong.

Note 2: This verb works as a prepositional verb constructor, with one preposition only (in parentheses: imperfect, subjunctive, past):
επισημαίνω (επί + σημαίνω): point out, single out (επισήμαινα, επισημάνω, επισήμανα)

Note: The above verb (in its forms λαμβάνω, λαβαίνω, λαμβάνομαι) serves as a prepositional verb constructor (in parentheses: imperfect, subjunctive, past):
αναλαμβάνω (ανά + λαμβάνω): undertake; recuperate (αναλάμβανα, αναλάβω, ανέλαβα)
αντιλαμβάνομαι (αντί + λαμβάνομαι): perceive; comprehend (αντιλαμβανόμουν, αντιληφθώ, αντιλήφθηκα)
απολαμβάνω (από + λαμβάνω): enjoy (απολάμβανα, απολαύσω, απόλαυσα) (notice the irregular-irregular subjunctive & past!)
εκλαμβάνω (εκ + λαμβάνω): misunderstand, take for smth. else (εξελάμβανα, εκλάβω, εξέλαβα)
επαναλαμβάνω (επί + ανά + λαμβάνω): repeat (επαναλάμβανα, επαναλάβω, επανέλαβα)
καταλαβαίνω (κατά + λαβαίνω): understand (to be encountered later) (καταλάβαινα, καταλάβω, κατάλαβα)
καταλαμβάνω (κατά + λαμβάνω): conquer, occupy (e.g., nation, position) (καταλάμβανα, καταλάβω, κατάλαβα/κατέλαβα)
καταλαμβάνομαι (κατά + λαμβάνομαι): seized by some feeling/attitude (καταλαμβανόμουν, καταληφθώ, καταλήφθηκα)
μεταλαβαίνω, and μεταλαμβάνω (μετά + λαμβάνω/λαβαίνω): receive Holy Communion (μεταλάβαινα/μεταλάμβανα, μεταλάβω, μετάλαβα/μετέλαβα)
παραλαμβάνω (παρά + λαμβάνω): receive (a delivery) (παραλάμβανα, παραλάβω, παρέλαβα)
περιλαμβάνω (περί + λαμβάνω): include (περιλάμβανα/περιελάμβανα, περιλάβω, περιέλαβα)
προλαβαίνω, and προλαμβάνω (προ + λαβαίνω/λαμβάνω): prevent (προλάβαινα, προλάβω, πρόλαβα)
προσλαμβάνω (προς + λαμβάνω): hire (to a company); take on (προσλάμβανα/προσελάμβανα, προσλάβω, προσέλαβα)
συλλαμβάνω (συν + λαμβάνω), arrest; conceive (child, idea) (συλλάμβανα/συνελάμβανα, συλλάβω, συνέλαβα)
συμπεριλαμβάνω (συν + περί + λαμβάνω): include (συμπεριλάμβανα/συμπεριελάμβανα, συμπεριλάβω, συμπεριέλαβα)

Note: There is no past participle for the above verb (“βρεμένο, -η, -ος” means “wet”, not “found”). To say that something “is found” the 3rd person sg. of present tense is used: βρίσκεται. Also, there is no middle imperative; to say “be located!” the 2nd person sg. of progressive subjunctive is used: να βρίσκεσαι!

Note: This is one more verb with identical vanilla and strawberry flavors. Its perfect senses are formed through another verb: γνωρίζω, which also means “I know”, but in a slightly different sense: “be aware/cognizant of”, “have intimate knowledge of” (akin to Spanish conocer; while ξέρω is akin to Sp. saber).

Note 1: The irregularity of the verb above is that its vanilla and strawberry stems are identical. Also note, the middle voice form has a different sense, “I refer to”, which is active in English. This sense is much more common than the passive “I am mentioned”. For example, the phrase “ο Ηρόδοτος αναφέρεται στους ελληνο-περσικούς πολέμους” means “Herodotus refers to [writes about] the Greco-Persian wars” (not that “Herodotus is mentioned in the Greco-Persian wars”).

Note 2: This verb is actually a compound one, made by the preposition ανά + the verb φέρω. It is listed explicitly here because of its high frequency of occurrence. Otherwise, all other compound (prepositional) verb forms of φέρω are listed here.

Note: The middle sense βάλθηκα is almost always followed by a verb in the subjunctive, hence the particle να... is included in the table above. Similarly in English, when the verb “set” is used in the same sense, it is almost always followed by an infinitive (to...), corresponding to the Greek subjunctive. Example: βάλθηκε να σπάσει όλα τα ρεκόρ (“s/he was set to break all records”).

Note: The above verb serves as a prepositional verb constructor (in parentheses: imperfect, subjunctive, past):
αναμένω (ανά + μένω): expect (ανέμενα, αναμείνω, ανέμεινα/ανάμεινα)
απομένω (από + μένω): be left over (απέμενα, απομείνω, απέμεινα)
διαμένω (διά + μένω): live (at a place) (διέμενα, διαμείνω, διέμεινα)
επιμένω (επί + μένω): insist, persist (επέμενα, επιμείνω, επέμεινα)
παραμένω (παρά + μένω): remain (παρέμενα, παραμείνω, παρέμεινα)
περιμένω (περί + μένω): wait; expect (περίμενα, περιμείνω, περίμεινα (but note: the past tense is not used))
προσμένω (προς + μένω): anticipate, look forward to (πρόσμενα/προσέμενα, προσμείνω, πρόσμεινα/προσέμεινα (but note: the past tense is not used))
υπομένω (υπό + μένω): endure; put up with (υπόμενα/υπέμενα, υπομείνω, υπόμεινα/υπέμεινα)

Note: The above verb is an eroded form of the compound prepositional verb εμβαίνω (εν + βαίνω). The verb βαίνω, although obsolete, is still used occasionally, meaning “proceed”, and is responsible for a number of other compound prepositional verbs (in parentheses: imperfect, subjunctive, past):
ανεβαίνω (ανά + εν + βαίνω): ascend, get on (ανέβαινα, ανεβώ, ανέβηκα)
αντιβαίνω (αντί + βαίνω): clash, go against (αντέβαινα, αντιβώ, αντέβην)
αποβαίνω (από + βαίνω): result (απέβαινα, αποβώ, απέβην)
επιβαίνω (επί + βαίνω): get on (a vehicle or an animal for transportation) (επέβαινα, επιβώ, επέβην)
επεμβαίνω (επί + εν + βαίνω): intervene, meddle, encroach (επέμβαινα, επέμβω, επέμβην/επέμβηκα)
κατεβαίνω (κατά + εν + βαίνω): descend, get down (κατέβαινα, κατεβώ, κατέβηκα)
μεταβαίνω (μετά + βαίνω): be transported (μετέβαινα, μεταβώ, μετέβην)
παραβαίνω (παρά + βαίνω): violate, infringe (παρέβαινα, παραβώ, παρέβην)
παρεμβαίνω (παρά + εν + βαίνω): interfere, intrude (παρέμβαινα, παρέμβω, παρέμβην/παρέμβηκα)
προβαίνω (προ + βαίνω): proceed, carry out a behavior (a demonstration, statement, etc.) (προέβαινα, προβώ, προέβην)
συμβαίνω (συν + βαίνω), happen (συνέβαινα, συμβώ, συνέβην)
υπερβαίνω (υπέρ + βαίνω): exceed (υπερέβαινα, υπερβώ, υπερέβην)
Of the above verbs, those that are very common, such as ανεβαίνω and κατεβαίνω, have “regularized” their endings in the past (-ηκα, -ηκες, -ηκε, -ήκαμε, -ήκατε, -ηκαν), while the rest retain their ancient past endings (-ην, ης, -η, -ημεν, -ητε, -ησαν). Such differences mean that the regularized forms are used in everyday speech, while the ancient/obsolete ones imply a more “learned” language use.

Note 1: An older (ancient) form of this verb is πίπτω (imperfect: έπιπτα), which can still be encountered occasionally in appropriate contexts and expressions.

Note 2: A few prepositional compound verbs are derived from πέφτω and πίπτω (in parentheses: imperfect, subjunctive, past):
εκπίπτω (εκ + πίπτω): (for a price): be discounted from a tax; (for a person): be exempted from duties (εξέπιπτα, εκπέσω, εξέπεσα)
καταπέφτω (κατά + πέφτω): fall down (possibly hitting smth. and causing destruction), collapse (κατάπεφτα, καταπέσω, κατάπεσα)
καταπίπτω (κατά + πίπτω): be discounted, subtracted from a price/sum; be annulled/nullified (κατέπιπτα, καταπέσω, κατέπεσα)
παραπέφτω (παρά + πέφτω): (for an object): be misplaced; (for a person, organization, nation, etc.) lose prior high status (παράπεφτα, παραπέσω, παράπεσα)

Note 1: The missing past participle is not a missing concept in Greek. To say, for example, “the proposed law”, the progressive present participle is used: “ο προτεινόμενος νόμος”. In Greek conceptualization, the act of proposing cannot be considered finished unless a decision is taken; hence the past participle is conceptually inappropriate for this verb.

Note 2: The above is actually a compound verb, the most common prepositional version of τείνω, which means “tend” (as in, “inclined to do smth.”). Τείνω forms several more prepositional verbs (in parentheses: imperfect, subjunctive, past):
ανατείνω (ανά + τείνω): raise against, hold up against (ανέτεινα, ανατείνω, ανέτεινα)

Note: The missing strawberry flavor is explained conceptually by the fact that this verb can be understood only in a progressive sense, not in an instantaneous one: if something “belongs”, it usually belongs with an implied duration, not instantly. This is true conceptually, so it is independent of the language we speak. Greek reflects this observation by lacking a strawberry flavor for this verb. English reflects it in a different way: the verb “to belong” conceptually still has a progressive aspect, which it “usurps” from its grammatically progressive form; thus, to say “I am belonging” sounds distinctly peculiar and unusual (though it is grammatically possible).

Note 1: The middle imperative “στάλσου” can be considered rare to objectionable (some native speakers might claim it is never uttered).

Note 2: This verb derives from the older form στέλλω (passive στέλλομαι), which is still used today in appropriate formal contexts. This older form is responsible for a number of compound prepositional verbs (in parentheses: imperfect, subjunctive, past):
αναστέλλω (ανά + στέλλω): suspend, postpone to an indefinite time (ανέστελλα, αναστείλω, ανέστειλα)
αντιδιαστέλλω (αντί + διά + στέλλω): compare by contrasting (= “παραβάλλω”) (αντιδιέστελλα, αντιδιαστείλω, αντιδιέστειλα)
αποστέλλω (από + στέλλω): send (= “στέλλω”), dispatch (απέστελλα, αποστείλω, απέστειλα)
διαστέλλω (διά + στέλλω): dilate, inflate, distend, expand (διέστελλα, διαστείλω, διέστειλα)
καταστέλλω (κατά + στέλλω): quell, repress, suppress (κατέστελλα, καταστείλω, κατέστειλα)
περιστέλλω (περί + στέλλω): limit, curb (περιέστελλα, περιστείλω, περιέστειλα)
υποστέλλω (υπό + στέλλω): lower (usu.: a flag) (υπέστελλα, υποστείλω, υπέστειλα)

Note 1: The idiomatic imperative form φεύγα (notice its vanilla flavor) is rather slang. The “normal” form is φύγε.

Note 2: A few compound prepositional verbs are formed with φεύγω (in parentheses: imperfect, subjunctive, past):
αποφεύγω (από + φεύγω): avoid, shun (απέφευγα/απόφευγα, αποφύγω, απέφυγα/απόφυγα)
διαφεύγω (διά + φεύγω): escape, get away; leak (usu.: profit, money) (διέφευγα, διαφύγω, διέφυγα)
εκφεύγω (εκ + φεύγω): be out of the jurisdiction/scope of (εξέφευγα, εκφύγω, εξέφυγα)
καταφεύγω (κατά + φεύγω): resort, take refuge (κατέφευγα, καταφύγω, κατέφυγα)
προσφεύγω (προς + φεύγω): recourse, turn to (usu.: to justice) (προσέφευγα, προσφύγω, προσέφυγα)

Etymology note: The English word fugitive has its root in the above Greek word.

Note 1: The original form of this verb in the present is τρώγω, but erosion has turned it into τρώω, to the extent that the form τρώγω is seldom ever used (and is probably dialectal). Erosion is applied to all persons in the present tense; thus, instead of the (antiquated) τρώγω, τρώγεις, τρώγει, τρώγουμε, τρώγετε, τρώγουν (or τρώγουνε), we now have: τρώω, τρως, τρώει, τρώμε, τρώτε, τρων (or τρώνε). However, no erosion occurs in the imperfect and imperative of the active voice, nor in the entire passive/middle voice (naturally: only the most common forms can be eroded).

Note 2: The peculiar middle sense of τρώγομαι (“I quarrel”) is rather slang, and should be avoided in formal, or slightly formal contexts (the more straightforward “μαλώνω” is recommended). Also note the expression “τρώγομαι με τα ρούχα μου”, (lit.: “I quarrel with my own clothes”) which means (in liberal translation), “I am so anxious to quarrel with sb. that, finding no suitable target, I start destroying/complaining about things that belong to me, or quarreling with people of my own circle/side/party.”

Note 3: A single prepositional compound verb is derived from τρώγω by prepending the preposition κατά:
κατατρώγω (κατά + τρώγω): eat up (e.g., from the inside), eat completely (κατάτρωγα/κατέτρωγα, καταφάω, κατάφαγα/κατέφαγα)
