Three declension patterns: δρόμος, πόρτα, σπίτι

You already know the article — it shows gender and case. Now the word itself changes together with it, and there are only three patterns: masculine in -ος, feminine in -α/-η, neuter in -ι/-ο. For example: “Η πόρτα του δωματίου είναι κλειστή” — The door of the room is closed. A rule from the Greek course: worked out on examples, not memorized as a wording.

How it works

You already know the article — it shows gender and case. Now the word itself changes together with it, and there are only three patterns: masculine in -ος, feminine in -α (-a)/-η (-i), neuter in -ι/-ο (-o).

The neuter is the simplest: its nominative and accusative are always identical. Το παράθυρο είναι ανοιχτό (to paráthiro íne anikhtó) and Άνοιξε το παράθυρο (ánikse to paráthiro) — one form, two jobs. Half of everyday words are neuter, so half of declension comes free.

The masculine drops its final in the accusative: ο δρόμος (o drómos) → τον δρόμο (ton drómo). The same with masculines in -ας (-as) and -ης: ο άντρας (o ándras) → τον άντρα (ton ándra), ο πωλητής (o politís) → τον πωλητή (ton polití). This is the easiest thing to forget and instantly audible.

The feminine, in the genitive, on the contrary grows a -ς: η πόρτα (i pórta) → της πόρτας (tis pórtas), η τιμή (i timí) → της τιμής (tis timís).

The genitive in Greek is a workhorse: it is "whose", it is "of what", and it covers what English does with "of": Η πόρτα του δωματίου (i pórta tu domatíu) — the door of the room; ο λογαριασμός του ρεύματος (o logariazmós tu révmatos) — the electricity bill.

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
