υπάρχω is more than the third-person existential υπάρχει / υπάρχουν. It has a complete personal active paradigm, and its aorist does two jobs that the imperfect cannot: it presents an existential event as bounded, and it serves as a perfective past of είμαι, “was/proved to be.”
Για εκείνον δεν υπάρχω πια, ούτε μου μιλάει.
ya ekínon dhen ipárcho pia, úte mu milái
As far as he's concerned, I no longer exist; he doesn't even speak to me.
Υπάρχεις; Δεν σε ακούω καθόλου.
ipárchis; dhen se akúo kathólu
Are you there? I can't hear you at all.
Principal parts
| Slot | Forms | Note |
|---|---|---|
| Present | υπάρχω, υπάρχεις, υπάρχει, υπάρχουμε, υπάρχετε, υπάρχουν | fully personal |
| Imperfect | υπήρχα, υπήρχες, υπήρχε, υπήρχαμε, υπήρχατε, υπήρχαν | continuing existence |
| Aorist | υπήρξα, υπήρξες, υπήρξε, υπήρξαμε, υπήρξατε, υπήρξαν | perfective existential; also perfective “be” |
| Dependent | υπάρξω | να / θα υπάρξω |
| Futures | θα υπάρχω / υπάρξω | continuous / bounded |
| Perfect | έχω υπάρξει | have existed; have been |
| Active participle | υπάρχων, υπάρχουσα, υπάρχον | (formal) |
| Mediopassive / passive participle | Does not exist: no ×υπάρχομαι and no -μένος form | |
| Imperative | Not used in ordinary Modern Greek | |
The stressed η in υπήρχα / υπήρξα is internal to this learned compound pattern; its mechanics belong to the internal augment. Unlike many augmenting compounds, υπάρχω retains it throughout the aorist: υπήρξαμε, υπήρξατε.
Do not broaden the missing passive-participle slot into “no participle,” because the learned active υπάρχων / υπάρχουσα / υπάρχον is alive in formal writing.
Η υπάρχουσα κατάσταση δεν μπορεί να συνεχιστεί.
i ipárchusa katástasi dhen borí na sinechistí
The current situation cannot continue. (formal)
υπήρχα versus υπήρξα
υπήρχα simply locates existence over an ongoing past interval. υπήρξα packages the state as a whole and can mean “was” in a life episode or “proved to be” in an evaluation. This is a lexical extension of the aorist, not a general replacement for every form of ήμουν.
Υπήρξα κι εγώ φοιτητής κάποτε, ξέρω τι περνάς.
ipírksa ki eghó fititís kápote, kséro ti pernás
I was a student once too; I know what you're going through.
Υπήρξες πολύ ευγενικός μαζί μου και δεν το ξέχασα.
ipírkses polí evyenikós mazí mu ke dhen to kséchasa
You were very kind to me, and I haven't forgotten it.
In the existential construction, the same aorist introduces a bounded development with an abstract noun: progress occurred, reactions arose, or difficulties materialized. The noun remains the subject and controls singular or plural agreement.
Υπήρξε κάποια πρόοδος, αλλά το πρόβλημα δεν λύθηκε.
ipírkse kápia próodhos, alá to próvlima dhen líthike
There was some progress, but the problem was not solved.
Θα υπάρξουν δυσκολίες στην αρχή, αλλά θα τις ξεπεράσουμε.
tha ipárksun dhiskolíes stin archí, alá tha tis kseperásume
There will be difficulties at first, but we'll overcome them.
The mechanics of postverbal agreement, colloquial existential έχει, and Greek's lack of dummy English there are covered on existential υπάρχει.
Government
υπάρχω is intransitive: it does not take a direct object. In its aorist “was/proved to be” sense, the complement is a nominative predicate noun or adjective, just as after είμαι: υπήρξα φοιτητής, not an accusative form.
Το σχέδιο υπήρξε αποτελεσματικό, παρά τις αρχικές αμφιβολίες.
to schédhio ipírkse apotelezmatikó, pará tis archikés amfivolíes
The plan proved effective despite the initial doubts. (formal)
The derivative family makes the same distinction visible: η ύπαρξη “existence,” υπαρκτός / ανύπαρκτος “real/nonexistent,” υπαρξιακός “existential,” and formal substantivized τα υπάρχοντά μου, “my belongings.”
Set phrases
- δεν υπάρχει περίπτωση — there is no chance / absolutely not
- δεν υπάρχει πρόβλημα — no problem
- Δεν υπάρχεις! — You're unbelievable! (informal praise)
- υπάρχουν και χειρότερα — things could be worse
- δεν υπάρχει τίποτα καλύτερο — there is nothing better
Δεν υπάρχει περίπτωση να προλάβουμε το τελευταίο τρένο.
dhen ipárchi períptosi na prolávume to teleftéo tréno
There's no chance we'll catch the last train.
Δεν υπάρχεις! Το έφτιαξες μόνος σου;
dhen ipárchis; to éftiakses mónos su;
You're unbelievable! Did you make it yourself? (informal praise)
Common Mistakes
❌ Η συμπεριφορά του υπήρχε υποδειγματική.
Incorrect — ongoing υπάρχω does not take a predicate adjective in this evaluative sense.
✅ Η συμπεριφορά του υπήρξε υποδειγματική.
i simberiforá tu ipírkse ipodhighmatikí
His conduct proved exemplary. (formal)
Do not treat υπάρχει as third-person-only or manufacture ×υπάρχομαι. Personal να υπάρξω and formal active υπάρχουσα are both real.
Key Takeaways
- υπάρχω · υπήρχα · υπήρξα · υπάρξω · έχω υπάρξει; the personal paradigm is complete.
- υπήρξα is both perfective existential and a perfective “was/proved to be.”
- No mediopassive, ordinary imperative, or passive participle; active υπάρχων, -ουσα, -ον survives formally.

- έχω (to have)A1 — The complete inventory of έχω on one card — present, the ει- past είχα, future, imperative and gerund — the slots it leaves empty (no aorist, no perfective stem, no perfect of itself, no passive), and the genuinely ambiguous έχω να construction.
- γίνομαι (to become/happen)A2 — One Greek verb covers become, happen and be-possible: Έγινε γιατρός, Τι έγινε;, Γίνεται; This card gives the paradigm — including the active-shaped aorist έγινα — the nominative predicate, the impersonal γίνεται, and the forms γίνομαι does not have.
- Existential υπάρχει (there is/are)A2 — Use υπάρχει or υπάρχουν with a following nominative noun to say ‘there is/are,’ without an English-style dummy ‘there’; colloquial speech also uses existential έχει.
- Impersonal and Dummy SubjectsB1 — English has two subjects that mean nothing — it and there — and Greek has neither, which produces two separate transfer errors with two separate fixes. 'It' corresponds to nothing at all (Βρέχει, Κάνει κρύο, Είναι κρίμα που…), while 'there is' is the real verb υπάρχει, which agrees, or the everyday έχει, which does not. Plus the neuter-singular adjective in Είναι δύσκολο να… and when αυτό genuinely is allowed.
