Negative Commands: μη(ν) + Subjunctive | Greek Grammar

Here is one of the cleanest structural surprises in Greek: there is no negative imperative. You learn to say Γράψε! (Write!), Έλα! (Come!), Φύγε! (Leave!) — and then discover that you cannot simply stick "don't" in front of them. There is no ×μη γράψε, no ×μη έλα, no ×μη φύγε. To forbid, Greek switches to a completely different structure: μη(ν) + the subjunctive (the plain verb form, without θα or να spelled out). For English speakers this is a genuine break, because English does just add "don't" to the same command — so the positive and negative commands feel like they should be symmetrical. In Greek they are built on different machinery.

The rule: μη(ν) + subjunctive

Take the particle μη(ν) and follow it with the second-person subjunctive — which, in the affirmative, is identical to the present or aorist verb form you would use after να:

Μην το κάνεις αυτό, θα το μετανιώσεις.

min to kánis aftó, tha to metaniósis

Don't do that, you'll regret it.

Μη φεύγεις ακόμα, μόλις ήρθες!

mi févyis akóma, mólis írthes

Don't leave yet, you just got here!

Μην ανησυχείς, θα τα καταφέρεις μια χαρά.

min anisichís, tha ta kataféris mia chará

Don't worry, you'll do just fine.

Παιδιά, μη μιλάτε την ώρα του μαθήματος.

pedhiá, mi miláte tin óra tu mathímatos

Kids, don't talk during the lesson.

The plural (μη μιλάτε) is, as always, both the plural and the polite singular. Notice there is no special "negative command verb" — the verb is just the ordinary subjunctive, and μη(ν) does all the prohibiting.

💡

The reason Greek uses the subjunctive here is deep: a prohibition is not a statement about reality, it is an attempt to keep something from becoming real. The subjunctive is precisely the mood of the not-yet-real — wishes, purposes, possibilities. A command "don't do it" belongs there naturally. This is also why the negator is μη(ν), the subjunctive/command negator, and not δεν, which negates statements of fact. The full split is on δεν vs μη(ν).

μη or μην? The final -ν rule

You will see both μη and μην. Keep the final -ν when the next word begins with a vowel or with one of κ, π, τ, ξ, ψ, μπ, ντ, γκ, τσ, τζ; drop it before the other consonants (β, γ, δ, ζ, θ, λ, μ, ν, ρ, σ, φ, χ). This alternation is live for μη(ν); do not flatten it into the learner default for δεν, which normally keeps its ν in current writing.

Keep μην	Drop to μη
Μην ξεχάσεις (before ξ)	Μη φεύγεις (before φ)
Μην το πεις (before τ)	Μη μιλάς (before μ)
Μην αργείς (before vowel)	Μη βιάζεσαι (before β)

Μην ξεχάσεις να κλείσεις τον φούρνο πριν φύγεις.

min ksechásis na klísis ton fúrno prin fíyis

Don't forget to turn off the oven before you leave.

Μη με περιμένεις για φαγητό, θα αργήσω.

mi me periménis ya fayitó, tha aryíso

Don't wait for me for dinner, I'll be late.

The aspect contrast survives into the negative

The aspect contrast remains, but negative directives have an important asymmetry. The imperfective can forbid a standing practice, stop an action in progress, or present even one immediate situation from inside. The perfective packages a prospective prohibition as bounded, often as a firm warning about a particular act or delimited set. Event count is therefore a strong cue, not a mechanical test.

Μη γράφεις με κόκκινο στυλό, δεν επιτρέπεται.

mi ghráfis me kókino stiló, dhen epitrépete

Don't write in red pen, it's not allowed. (as a rule)

Μη φεύγεις ακόμα, περίμενε πέντε λεπτά.

mi févyis akóma, períme pénte leptá

Don't leave yet; wait five minutes. (one immediate situation viewed internally)

Μη γράψεις το όνομά σου στο τεστ, είναι ανώνυμο.

mi ghrápsis to ónomá su sto test, íne anónimo

Don't write your name on the test, it's anonymous. (this once)

Μην τηλεφωνήσεις σε κανέναν από τους τρεις μέχρι να σε πάρω.

min tilefonísis se kanénan apó tus tris méchri na se páro

Don't call any of the three until I call you. (delimited set → perfective)

Positive and negative directives share the bounded/internal contrast, but the common one-off Μη φεύγεις ακόμα shows why a prohibition cannot be reduced to "once versus always." See Aspect in the Imperative and the Imperfective Imperative.

The pronoun flips back to the front

This is the detail that catches everyone. After a positive imperative the object pronoun leans on the end of the verb (Δώσε μου το). But because the negative command is really a subjunctive clause introduced by μη(ν), the pronoun goes back to its normal place before the verb:

Δώσε μου το κλειδί της αποθήκης.

dhóse mu to klidhí tis apothíkis

Give me the key to the storeroom. (positive — pronoun after)

Μη μου δίνεις το κλειδί ακόμα, θα το χάσω.

mi mu dhínis to klidhí akóma, tha to cháso

Don't give me the key yet, I'll lose it. (negative — pronoun before)

So the positive and negative of the same command mirror each other in two ways at once: the verb form changes (imperative → subjunctive) and the pronoun jumps from behind the verb to in front of it. The enclitic side of this is on Clitics With the Imperative, and the broader prohibition patterns on Negative Commands and Prohibitions.

Common Mistakes

1. Negating the imperative form directly. This is the headline error: there is no ×μη + imperative. Swap in μη(ν) + subjunctive.

❌ Μη γράψε τίποτα ακόμα.

Incorrect — there is no negative imperative; use μη + subjunctive: Μη γράψεις.

✅ Μη γράψεις τίποτα ακόμα.

mi ghrápsis típota akóma

Don't write anything yet.

2. Dropping -ν before a vowel. Before a vowel the particle must keep its -ν.

❌ Μη ανησυχείς για το αποτέλεσμα.

Incorrect — before a vowel the -ν stays: Μην ανησυχείς.

✅ Μην ανησυχείς για το αποτέλεσμα.

min anisichís ya to apotélezma

Don't worry about the result.

3. Leaving the pronoun after the verb, as in the positive command. In the negative it moves in front.

❌ Μη λες μου ψέματα.

Incorrect — in a negative command the clitic precedes the verb: Μη μου λες.

✅ Μη μου λες ψέματα.

mi mu les psémata

Don't lie to me.

4. Assuming every directive-like δεν sentence is ungrammatical. Greek can use an emphatic indicative as a rebuke, much as English can say “You don't talk to me like that!” The productive prohibition construction itself uses μη(ν).

Δεν μιλάς έτσι στη μητέρα σου!

dhen milás étsi sti mitéra su

You don't talk to your mother like that! (emphatic indicative rebuke)

Μη μιλάς έτσι στη μητέρα σου!

mi milás étsi sti mitéra su

Don't talk to your mother like that! (direct prohibition)

Key Takeaways

Greek has no morphologically negative imperative; its ordinary productive prohibition is μη(ν) + subjunctive (Μην το κάνεις, Μη φεύγεις).
The productive prohibition uses μη(ν); δεν ordinarily negates indicatives, though an emphatic indicative can pragmatically function as a rebuke.
μην keeps its -ν before a vowel or κ, π, τ, ξ, ψ, μπ, ντ, γκ, τσ, τζ; elsewhere it is μη.
The aspect contrast persists, but not as a count switch: imperfective can cover a standing rule, an unfolding action, or one immediate situation; perfective packages a particular act or delimited set as bounded.
Object pronouns move before the verb in a negative command (Μη μου το λες), the mirror image of the positive Δώσε μου το.
