Mood is the verb's way of saying what kind of statement it's making: is this a fact, a wish, a command? Greek has three moods — indicative, subjunctive and imperative — but it builds them very differently from English or the other Romance languages. The headline for an English speaker: the Greek subjunctive is not a special set of endings to memorise. It is a particle, να, placed in front of an ordinary conjugated verb. Master να and you have unlocked a huge slice of the language.
The indicative: stating facts
The indicative is the default. It states things as real: what is, was, or will be. Every plain present, past and future you meet is indicative.
Μένω στη Θεσσαλονίκη εδώ και πέντε χρόνια.
méno sti Thesaloníki edhó ke pénde chrónia
I've been living in Thessaloniki for five years.
Χθες πήγαμε σινεμά με την παρέα.
chthes píghame sinemá me tin paréa
Yesterday we went to the cinema with the gang.
Το τρένο φεύγει στις οκτώ ακριβώς.
to tréno févyi stis októ akrivós
The train leaves at eight o'clock sharp.
The ordinary future with θα (θα φύγω, “I'll leave”) counts as indicative: it presents a future assertion rather than creating a fourth mood. θα also has modal uses, introduced on the modal-particles overview.
The subjunctive: να + a verb
Here is the structural surprise. Where Spanish and French have a separate subjunctive conjugation (hable, parle), Greek has no special subjunctive endings. Instead it puts να before a conjugated verb for wishes, purpose, obligation, possibility — and where English uses productive to + verb. A restricted invariant form such as γράψει survives inside perfect constructions (έχω γράψει) but cannot function as a free infinitive; see the loss of the infinitive.
Θέλω να μάθω ελληνικά μέχρι το καλοκαίρι.
thélo na mátho eliniká méchri to kalokéri
I want to learn Greek by the summer.
Πρέπει να πληρώσουμε τον λογαριασμό.
prépi na plirósume ton loghariazmó
We have to pay the bill.
Ήρθα να σε βοηθήσω με τις βαλίτσες.
írtha na se voithíso me tis valítses
I came to help you with the suitcases.
The verb after να still conjugates for its own subject and still carries an aspect choice (να γράφω views the writing internally or as ongoing; να γράψω packages it as bounded). Both points have their own homes: subject agreement is on the loss of the infinitive, and the full range of uses is on the subjunctive overview.
The imperative: giving commands
The imperative is a genuine third mood with its own endings, used for direct commands. Where both stems exist, γράψε (perfective) packages the requested writing as bounded, while γράφε (imperfective) presents it internally, habitually, or as something to continue.
Κλείσε την πόρτα, σε παρακαλώ, κρυώνω.
klíse tin pórta, se parakaló, krióno
Close the door, please, I'm cold.
Πρόσεχε στον δρόμο, έχει πάγο.
próseche ston dhrómo, échi págho
Be careful on the road, it's icy.
To tell someone not to do something, Greek can't use the imperative form — it switches to μη(ν) + a να-style verb: μην τρέχεις (don't run), μην ανοίξεις (don't open it). The full command system, positive and negative, is on the imperative overview.
Μην ανησυχείς, όλα θα πάνε καλά.
min anisichís, óla tha páne kalá
Don't worry, everything will be fine.
ας: the "let's / let him" particle
Greek has a small extra particle, ας, for suggestions and concessions — roughly English "let's" (first person plural) or "let him/her/them" (third person). It fills the gap where the imperative can't reach, since you can't literally command yourself or a third party.
Ας πάμε μια βόλτα, έχει ωραίο καιρό.
as páme mia vólta, échi oréo keró
Let's go for a walk — the weather's nice.
Ας το κάνει όποιος θέλει, εγώ κουράστηκα.
as to káni ópios théli, eghó kurástika
Let whoever wants to do it — I'm worn out.
The particle family: θα, να, ας, μη(ν)
Notice that three of the moods lean on little preverbal particles that all sit in the same slot, right before the verb (and before any weak pronoun): θα for the future/conditional, να for the subjunctive, ας for suggestions, and μη(ν) for the negative of commands and the subjunctive. English does this work with separate modal verbs (will, may, let, don't); Greek does it with these one-syllable particles. They are gathered on the modal-particles overview.
Θα έρθω το βράδυ, να μου κρατήσεις θέση.
tha értho to vrádhi, na mu kratísis thési
I'll come tonight — save me a seat.
Common Mistakes
1. Looking for special subjunctive endings. There are none — the subjunctive is just να + the ordinary verb form.
❌ Θέλω γράφω ένα γράμμα.
Incorrect — the subordinate verb needs να: θέλω να γράψω.
✅ Θέλω να γράψω ένα γράμμα.
thélo na ghrápso éna ghráma
I want to write a letter.
2. Choosing the neutral prohibition pattern. μη(ν) + verb is neutral; δεν + indicative can instead sound like a categorical rule or emphatic refusal.
✅ Δεν τρέχεις στον διάδρομο!
dhen tréchis ston dhiádhromo!
You do not run in the corridor! (grammatical as a categorical rule or stern directive)
✅ Μην τρέχεις στον διάδρομο!
min tréchis ston dhiádhromo!
Don't run in the corridor!
3. Marking a suggestion explicitly. An indicative can announce a plan or make a context-driven proposal; ας + verb (or να + verb) marks the suggestion overtly.
✅ Πηγαίνουμε για καφέ!
piyénume ya kafé!
We're going for coffee! / Let's go for coffee! (indicative; announcement or context-driven proposal)
✅ Ας πάμε για καφέ!
as páme ya kafé!
Let's go for a coffee!
Both forms are grammatical; ας πάμε makes the invitational force explicit without relying on context.
Key Takeaways
- Three moods: indicative (facts), subjunctive (να
- verb), imperative (commands).
- The subjunctive is να + a conjugated verb and fills the productive complement slot where English commonly uses to + verb; an invariant infinitival remnant survives only inside perfect constructions.
- The neutral negative-command construction is μη(ν) + verb; δεν remains indicative but can pragmatically deliver a categorical rule or stern directive.
- ας covers "let's / let him"; together with θα, να, μη(ν) it forms the particle family that drives Greek's non-indicative forms.
