Adjectives agree: μαύρος, μαύρη, μαύρο

A Greek adjective changes together with its noun — by gender, number and case. There are three patterns, and the first covers most words: -ος, -η, -ο (μαύρος, μαύρη, μαύρο). For example: “Θέλω ένα μαύρο παντελόνι” — I want black trousers. A rule from the Greek course: worked out on examples, not memorized as a wording.

How it works

A Greek adjective changes together with its noun — by gender, number and case. There are three patterns, and the first covers most words: -ος, -η (-i), -ο (μαύρος (mávros), μαύρη (mávri), μαύρο (mávro)).

The second is the same, but with (-a) instead of -η in the feminine, and it is switched on by a purely spelling signal: a vowel or an ρ right before the ending. ωραίος — ωραία (oréa), νέος (néos) — νέα (néa), κρύος (kríos) — κρύα (kría). Nothing to hear here — just look at the second letter from the end.

The third is a short set in -ύς, -ιά, -ύ: μακρύς (makrís), μακριά (makriá), μακρύ (makrí); φαρδύς (fardís), φαρδιά, φαρδύ (fardí); βαρύς (varís), βαριά (variá), βαρύ (varí). There are a couple of dozen such words, and nearly all are about size and weight — that is, they will meet you in this very unit.

And apart stand those that never change: the borrowed colors μπλε (ble), γκρι (gri), καφέ (kafé), ροζ, μοβ. το μπλε φόρεμα (to ble fórema), τα μπλε παπούτσια (ta ble papútsia) — one form for everything. This is not the language being lazy: a word that fits no Greek pattern simply stays put.

The adjective stands before the noun, and the article repeats with it in the definite construction: το κόκκινο φόρεμα (to kókino fórema). As a predicate there is no article: Το φόρεμα είναι κόκκινο (to fórema íne kókino).

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.
