English builds nouns out of other material with suffixes and with the -ing form: good → goodness, to lie → lying. Greek barely needs either. It puts an article in front of the thing and the thing is now a noun. An adjective, an adverb, a prepositional phrase, a whole clause, a quoted word, a date — anything you can say can be made into a noun phrase by prefixing το.
This is not a curiosity at the edge of the grammar. It is how Greek does abstraction, and once you can use it, a whole register of the language opens up: it is the difference between talking about things and talking about the fact that, the way that, the pros and the cons.
Why the article is usually το
The nominalizing article is overwhelmingly the neuter το/τα, and there is a reason. Neuter is Greek's unmarked gender — the gender the language falls back on when a thing has no grammatical hook of its own, which is also why it is the gender assigned to most loanwords (see gender of loanwords). A να-clause has no gender. A quoted word has no gender. An adverb has no gender. So they all get the default, and the default is neuter.
The other genders appear too, but only when the nominalized phrase refers to a person whose gender is known.
1. Article + adjective
The simplest case, and the one that flows straight out of the article-adjective bracket: drop the noun and the article carries the phrase. What changes with the gender and number is the kind of meaning you get.
| Form | Reading | Example |
|---|---|---|
| masculine / feminine sg. | a person | ο μεγάλος (the eldest), η μικρή (the little girl) |
| masculine pl. | a class of people | οι πλούσιοι (the rich), οι νέοι (the young) |
| neuter sg. | an abstract quality | το καλό (the good), το ωραίο (beauty) |
| neuter pl. | concrete instances, "the … bits" | τα καλά (the upsides), τα παλιά (the old days) |
Ο μεγάλος σπουδάζει στη Θεσσαλονίκη, η μικρή πάει ακόμα σχολείο.
o meghálos spudházi sti Thesaloníki, i mikrí pái akóma scholío
The eldest is studying in Thessaloniki, the little one is still at school.
Οι πλούσιοι δεν περιμένουν ποτέ στην ουρά.
i plúsii dhen periménun poté stin urá
Rich people never wait in line.
Τα καλά της δουλειάς είναι το ωράριο και οι συνάδελφοι.
ta kalá tis dhuliás íne to orário ke i sinádhelfi
The good things about the job are the hours and the colleagues.
The singular/plural split here is worth internalising: το καλό is goodness, an abstraction; τα καλά is the good points, a list you could count. The same pair works for almost any adjective — το δύσκολο (the difficult part) vs τα δύσκολα (the hard times).
Μη μου κάνεις τον έξυπνο, ξέρω τι έγινε.
mi mu kánis ton éksipno, kséro ti éyine
Don't play the smart guy with me — I know what happened. (informal)
2. Article + adverb
Adverbs of time and place take an article and become nouns just as easily. Το αύριο, το χθες, το τώρα, το μετά are ordinary Greek, not poetry.
Το αύριο δεν το ξέρει κανείς, γι' αυτό μη σχεδιάζεις τόσο.
to ávrio dhen to kséri kanís, yaftó mi schedhiázis tóso
Nobody knows what tomorrow holds, so don't plan so much.
Ακόμα ζει στο χθες, μιλάει συνέχεια για τη δεκαετία του ογδόντα.
akóma zi sto chthes, milái sinéchia ya ti dhekaetía tu oghdhónda
He still lives in the past — he talks non-stop about the eighties.
3. Article + prepositional phrase
A prepositional phrase with an article in front of it becomes either a noun ("the pros") or a modifier sitting inside another noun phrase ("the downstairs neighbour").
Ζυγίσαμε τα υπέρ και τα κατά και τελικά μείναμε.
ziyísame ta ipér ke ta katá ke teliká míname
We weighed up the pros and cons and in the end we stayed.
Ο από κάτω γείτονας παραπονιέται για τον θόρυβο κάθε βράδυ.
o apó káto yítonas paraponiéte ya ton thórivo káthe vrádhi
The neighbour downstairs complains about the noise every night.
The learned-flavoured τα του... pattern belongs here too: τα του σπιτιού (household matters), τα περί απεργίας (the whole strike business) (journalistic). It is a genitive phrase nominalized by τα.
Τα του σπιτιού τα κανονίζει εκείνη, εγώ απλώς πληρώνω.
ta tu spitiú ta kanonízi ekíni, eghó aplós pliróno
She handles the household side of things; I just pay. (slightly formal)
An article can also nominalize a bare genitive, which is where the very common "at someone's place" construction comes from — and yes, στου / στης are perfectly real forms, σε fused with the genitive article:
Πάμε στου Νίκου, έχει μεγάλη βεράντα.
páme stu Níku, échi megháli veránda
Let's go to Nikos's place, he's got a big balcony.
4. Article + να-clause — Greek's productive infinitival substitute
Modern Greek has no productive infinitive that can fill the English to + verb slot (see no infinitive: the να-clause). A restricted invariant form survives inside perfect constructions, but it cannot serve here. Where English says lying is wrong or to lie is wrong, Greek says το να λες ψέματα: the article makes a finite clause behave as a noun, so it can be a subject, an object, or the complement of a preposition.
Το να λες ψέματα σε φίλους δεν βγάζει πουθενά.
to na les psémata se fílus dhen vgházi puthená
Lying to friends gets you nowhere.
Το να ξυπνάω νωρίς είναι μαρτύριο για μένα.
to na ksipnáo norís íne martírio ya ména
Getting up early is torture for me.
Two things to notice. First, the verb stays fully conjugated — να λες is second person, να ξυπνάω is first person — so unlike an English gerund, the Greek nominalization carries a subject inside it. Second, when a true preposition selects the nominalized activity, the article marks that nominal status: με το να, από το να. Do not confuse this with fixed linkers such as purpose για να or ordinary αντί να, which introduce a clause without το.
Με το να φωνάζεις δεν λύνεται τίποτα.
me to na fonázis dhen línete típota
Shouting doesn't solve anything.
5. Article + ότι / πώς clause
The same trick applies to that-clauses and to indirect questions, giving Greek a compact equivalent of English the fact that and the way that.
Το ότι δεν τηλεφώνησε με πείραξε περισσότερο από όλα.
to óti dhen tilefónise me pírakse perisótero apó óla
The fact that he didn't call bothered me more than anything.
Με ενοχλεί το πώς μου μιλάει μπροστά σε κόσμο.
me enochlí to pos mu milái brostá se kózmo
What gets to me is the way he talks to me in front of people.
6. Article + literally anything
Once you see the mechanism, the rest follows. A quoted word, a letter, a year, a fixed phrase — the article makes it a noun.
Το «όχι» της ήταν κατηγορηματικό και δεν ξαναρώτησα.
to «óchi» tis ítan katighorimatikó ke dhen ksanarótisa
Her 'no' was categorical, and I didn't ask again.
Το πάρε δώσε με την εφορία θέλει υπομονή.
to páre dhóse me tin eforía théli ipomoní
Dealing with the tax office takes patience. (informal)
Μόλις ακούστηκε η είδηση, έγινε το έλα να δεις.
mólis akústike i ídhisi, éyine to éla na dhis
The moment the news broke, all hell broke loose. (informal)
Note what has happened in the last two: το πάρε δώσε and το έλα να δεις are strings of imperatives, frozen and then nominalized. Greek also keeps a few learned survivals of the ancient infinitive in exactly this frame — το ευ ζην ("the good life") (learned) — which are worth recognising but not imitating; see katharevousa survivals.
Common Mistakes
1. Using the gerund as a subject. The Greek -οντας form is an adverb, not a noun; it can never be the subject of a sentence.
❌ Διαβάζοντας είναι ο καλύτερος τρόπος να μάθεις.
Incorrect — the -οντας gerund can't be a subject; use Το να διαβάζεις.
✅ Το να διαβάζεις είναι ο καλύτερος τρόπος να μάθεις μια γλώσσα.
to na dhiavázis íne o kalíteros trópos na máthis mia ghlósa
Reading is the best way to learn a language.
2. Dropping το after με when it governs a nominalized activity. This use of με selects the whole το να noun phrase; the rule does not extend to linkers such as για να or αντί να.
❌ Κουράστηκα με να περιμένω.
Incorrect — a preposition needs the nominalizing article: με το να περιμένω.
✅ Κουράστηκα με το να περιμένω απαντήσεις που δεν έρχονται.
kurástika me to na periméno apandísis pu dhen érchonde
I got tired of waiting for answers that never come.
3. Using neuter singular for a class of people. The poor, the young, the unemployed are masculine plural in Greek; neuter singular gives you an abstraction or an object.
❌ Το άνεργο χρειάζεται στήριξη, όχι συμβουλές.
Incorrect — a group of people takes the masculine plural: οι άνεργοι.
✅ Οι άνεργοι χρειάζονται στήριξη, όχι συμβουλές.
i áneryi chriázonde stíriksi, óchi simvulés
Unemployed people need support, not advice.
4. Leaving a that-clause bare in subject position. A fronted ότι-clause needs the article to be a noun phrase.
❌ Ότι δεν με εμπιστεύεται με πονάει.
Incorrect — a fronted that-clause needs the article: Το ότι δεν με εμπιστεύεται.
✅ Το ότι δεν με εμπιστεύεται με πονάει περισσότερο απ' όσο φαντάζεσαι.
to óti dhen me embistévete me ponái perisótero ap óso fandázese
The fact that he doesn't trust me hurts more than you imagine.
5. Writing σε and the genitive article separately. The fusion into στου / στης / στων is obligatory, exactly as it is for στον / στη / στο.
❌ Έμεινα σε της αδερφής μου το Σαββατοκύριακο.
Incorrect — σε + της fuse: στης αδερφής μου.
✅ Έμεινα στης αδερφής μου το Σαββατοκύριακο.

I stayed at my sister's over the weekend.
Key Takeaways
- An article turns anything into a noun. This is the single most productive piece of Greek syntax.
- The default article is neuter το/τα, because neuter is the unmarked gender; masculine and feminine appear when a person is meant.
- With adjectives, gender and number choose the reading: οι πλούσιοι (people), το καλό (abstraction), τα καλά (concrete instances).
- Το να + verb is Greek's productive substitute for an English infinitival or gerund noun phrase; a restricted invariant form survives separately inside perfect constructions.
- Το ότι / το πώς give you English's the fact that and the way that.
- Adverbs (το αύριο), prepositional phrases (τα υπέρ και τα κατά, ο από κάτω γείτονας), genitives (στου Νίκου), quoted words (το «όχι») and frozen imperative strings (το έλα να δεις) all nominalize the same way.
