The Passive Participle -μένος

Every Greek verb that can be made passive hands you a participle in -μένος / -μένη / -μένο: γράφω gives γραμμένος (written), κλείνω gives κλεισμένος (shut), κουράζω gives κουρασμένος (tired). Once it exists it behaves exactly like an ordinary adjective — that adjectival life (how it agrees, where the accent sits, how it differs from the -τος adjective) is the subject of passive participles as adjectives. This page takes the verb's side: where the participle comes from, why its middle consonant looks the way it does, and the work it does inside the passive verb system. Get the formation right and the adjective takes care of itself.

One passive-perfect stem, two frozen products

Greek's passive perfect is built on a single special stem — call it the passive-perfect stem — and that stem throws off two frozen forms you will meet again and again:

• the invariable απαρέμφατο in -εί (γραφτεί, κουραστεί), which pairs with έχω for the event perfect — έχει γραφτεί, "it has been written";
• the declinable participle in -μένος (γραμμένος, κουρασμένος), which pairs with είμαι for the state — είναι γραμμένο, "it is (in a) written (state)."

They are siblings: the same underlying stem, dressed once as a rigid verbal ending and once as a full adjective. The -εί half — how to build it and when it is used — is laid out on the perfect in the passive. Here we build the -μένος half.

How the participle is built

The recipe is: take the verb's passive-perfect stem and add -μένος (masculine), -μένη (feminine), -μένο (neuter). The ending is dead regular; all the action is in the consonant right before -μένος, and that consonant is where the verb's own history shows through. Greek verbs sort into a handful of tidy patterns by that consonant:

Three broad groups cover almost everything. Verbs whose root ends in a dental or -ζ sound go to -σμένος (κλεισμένος, κουρασμένος, χαλασμένος, σπασμένος). Verbs whose root ends in a labial (φ, β, π) collapse it to a double -μμένος (γραμμένος, βαμμένος, κρυμμένος, αναμμένος). Verbs whose root ends in a velar (γ, κ, χ) go to -γμένος (ανοιγμένος, τυλιγμένος, πνιγμένος). A smaller set drops the consonant altogether and adds -μένος straight onto a vowel (πλυμένος, δεμένος, ντυμένος, χαμένος).

Its stem is (usually) the passive aorist's stem

Here is the shortcut that makes -μένος learnable instead of memorisable: for most verbs the -μένος participle shares its stem with the passive aorist in -θηκα. If you already know κουράστηκε, you already know κουρασμένος; if you know κλείστηκε, you know κλεισμένος. Same stem, different jobs.

But be honest with yourself about one group that refuses to line up. A cluster of very common verbs keeps an older, different consonant in the participle than in the aorist — the participle preserves an ancient perfect stem while the aorist went its own way:

There is no rule that rescues you here — γράφτηκε but γραμμένος, βάφτηκε but βαμμένος simply have to be learned as pairs. The good news is that the list is short and the verbs are so frequent that a week of reading fixes them.

The accent never moves off the -μέ-

One spelling fact locks in the whole class: every -μένος participle is stressed on the -μέ- syllable, and it stays there through the entire paradigm. So κουρασμένος gives κουρασμένου, κουρασμένοι, κουρασμένες, κουρασμένα — the accent glued to -μέ- the whole way down. Unlike the nouns and other adjectives that shift their stress in the genitive, this one never does. Put the accent anywhere else (×κούρασμενος) and it is simply wrong.

Its main job: the είμαι-perfect passive

The reason this participle earns a place in the verb system, not just the adjective section, is that it is the participle half of the passive perfect built with είμαι. Put είμαι / ήταν in front of an agreeing -μένος form and you have said that something now stands in a completed condition:

Because the participle is an adjective, it agrees with its subject — σβησμένα with φώτα (neuter plural), πληρωμένος with λογαριασμός (masculine singular). The full agreement and declension story, and how this state form contrasts with the invariable έχω γραφτεί event perfect, are on the perfect in the passive. Keep one thing straight from the start: είμαι pairs with -μένος, never with the -εί form.

State vs event: -μένος against the -θηκα aorist

Now the distinction this page most needs to make, and the one English hides. Take a single verb and look at its two passive faces:

• the -μένος participle names the state that results — το γράμμα είναι γραμμένο, "the letter is (in a) written (state)";
• the passive aorist in -θηκα names the event that produced it — το γράμμα γράφτηκε χθες, "the letter was written yesterday (it happened)."

English lets "the door was closed / the letter was written" cover both a state and an event; Greek forces you to choose. If you can point at the thing now and describe its condition, use -μένος. If you are reporting the moment it got done — often with a time or an agent — use the aorist verb.

Read the pair together: ήταν μαγειρεμένο photographs the standing result; μαγειρεύτηκε narrates the cooking. The same split runs through every transitive verb — σβησμένα φώτα (they stand off) versus τα φώτα σβήστηκαν (someone switched them off), δεμένη βάρκα (it stands tied) versus η βάρκα δέθηκε (it got tied).

Common Mistakes

1. Moving the accent off the -μέ-. The stress is fixed on that syllable in every form.

2. Copying the aorist stem into the participle for the irregular verbs. γράφτηκε does not give ×γραφμένος; the participle is γραμμένος.

3. Using the -μένος state form to report a past event. A one-off action in the past is the aorist verb, not είμαι/ήταν + participle.

4. Pairing the participle with έχω on its own. A bare nominative -μένος cannot follow έχω; use είμαι + -μένος for the state or έχω + -εί for the event.

Key Takeaways

• The passive participle -μένος / -μένη / -μένο is the declinable product of the passive-perfect stem; its invariable sibling is the -εί απαρέμφατο that goes with έχω.
• Build it by adding -μένος to the passive-perfect stem; the stem-final consonant sorts into -σμένος (κλεισμένος, κουρασμένος), -μμένος (γραμμένος, βαμμένος), -γμένος (ανοιγμένος), and bare-vowel -μένος (πλυμένος, δεμένος).
• For most verbs the participle shares the stem of the passive aorist (κουράστηκε → κουρασμένος); a frequent irregular group does not (γράφτηκε → γραμμένος, βάφτηκε → βαμμένος) and must be learned as pairs.
• The accent is fixed on the -μέ- throughout the paradigm — never ×κούρασμενος.
• Its core verbal job is the είμαι-perfect passive (είναι σβησμένα, είναι πληρωμένος); it agrees like any adjective, detailed on participles as adjectives.
• -μένος names the state, the -θηκα aorist names the event: ήταν μαγειρεμένο (it stood cooked) vs μαγειρεύτηκε (it got cooked).
