The Subjunctive With να

If there is one word that unlocks half of Greek syntax, it is να. Greek has no infinitive — there is no single "to go," "to eat," "to leave" form the way English has. Everywhere English reaches for to + verb ("I want to go") or a that-clause after a wish ("I want that you leave"), Greek reaches for να + a fully conjugated verb. Learn how να works and an enormous amount of the language suddenly clicks into place: modals, purpose, wishes, polite requests, and most subordinate clauses all run through it.

να replaces the missing infinitive

Because Greek lost the infinitive, it cannot say "×I want to go" with a single frozen verb form. Instead it links two verbs with να, and the second verb is fully conjugated — it carries a person and a number just like any other verb.

Notice the range already: θέλω να (a wish), ήρθα να (a purpose — "I came in order to…"), μπορεί να (a possibility). One particle covers all of them. The να itself never changes; it is a bare, unstressed function word (it never carries its own accent) that simply flags: what follows is not a plain statement of fact.

The verb after να keeps its own subject

This is the single biggest mental shift for an English speaker. English marks a change of subject by adding an object: "I want to leave" versus "I want you to leave." Greek doesn't add anything — it just conjugates the second verb to whichever person you mean, and the ending does all the work.

Same main verb, same να — only the ending of the second verb changed, from -ω (I) to -εις (you), and the whole meaning flipped. There is no separate word for "you" here; the -εις is the "you." This is why you must think of the να-verb as a real, live verb with its own subject, not a fixed "to"-form.

The aspect choice lives on the stem

Every να-verb comes in two shapes, because Greek verbs have two stems: an imperfective one and a perfective one. So there is no single "να γράφω/να γράψω" — you must pick. να γράφω views the action as ongoing or habitual; να γράψω views it as a single, complete act.

This choice is the hardest thing about να for English speakers, precisely because English "to watch" carries no such distinction. It is covered in full on the να-present (imperfective), the να-aorist (perfective), and the decision page, aspect after να.

The θα / να / ας family

να is one of three little particles that sit in front of a finite verb and reshape its meaning. They are worth seeing side by side, because learners mix them up.

All three take the same two-stem aspect choice, but they mean very different things: θα states what will happen (see the future with θα), να flags something wished-for or aimed-at, and ας urges an action (see the hortative ας).

Negating a να-clause: μη(ν), not δεν

Ordinary statements are negated with δεν (δεν φεύγω, "I'm not leaving"). But a να-clause is not an ordinary statement, and it takes a different negator: μη or μην. Reaching for δεν after να is one of the most persistent learner errors.

The distinction between δεν and μην is worked out on its own page, δεν vs μην.

Where να shows up — the map

να is not a single construction but a whole department of the grammar. Here is where the rest of it lives, so you can go deeper wherever you need to:

• After modal verbs — θέλω να, μπορώ να, πρέπει να, ξέρω να: see να after modal verbs.
• After verbs of emotion and evaluation — χαίρομαι να, φοβάμαι να: see να after emotion verbs.
• To express purpose ("in order to") with για να: see purpose clauses with για να.
• As a standalone wish or soft command — Να περάσεις καλά!: see standalone να.
• With the impersonal πρέπει / μπορεί: see impersonal πρέπει & μπορεί να.
• In deliberative questions — Να φύγουμε;: see να in questions.
• Chosen over ότι/πως for "that"-clauses: see να vs ότι.
• After the subordinators πριν, μέχρι, χωρίς, αντί — where English uses "before doing / without doing": see να after πριν, μέχρι, χωρίς, αντί.
• Nominalized with the article — Το να μαθαίνεις γλώσσες…: see το να-clauses.

Common Mistakes

1. Dropping να after a modal. English "I can help" has no "to," so learners omit the linker. Greek always needs να between the two verbs.

2. Negating with δεν instead of μην. After να, the negator is μη(ν).

3. Adding an object pronoun for a different subject. English says "I want you to come"; Greek puts that "you" into the verb ending, not into a separate pronoun.

4. Using ότι ('that') after a verb of wanting. Desire and volition always take να, never the fact-reporting ότι/πως.

Key Takeaways

• να + a fully conjugated verb replaces the missing infinitive and the English "to + verb" / "that + clause".
• The verb after να keeps its own subject: θέλω να φύγω (I leave) vs θέλω να φύγεις (you leave) — the ending, not a pronoun, marks who.
• The aspect choice sits on the stem: να γράφω (ongoing/habitual) vs να γράψω (single act).
• να belongs to the θα / να / ας family: θα = future, να = subjunctive, ας = let's.
• A να-clause is negated with μη(ν), never δεν.
