Words that decline differently: η πόλη, το μέρος

Three patterns cover most nouns, but not all of them. What is left is a small and very frequent set, worth knowing by sight. For example: “Η γενέτειρά μου είναι μια μικρή πόλη” — My hometown is a small town. A rule from the Greek course: worked out on examples, not memorized as a wording.

How it works

Three patterns cover most nouns, but not all of them. What is left is a small and very frequent set, worth knowing by sight.

Feminine in -η (-i), plural in -εις: η πόλη (i póli) → οι πόλεις (i pólis). Nearly everything in -ση and -ξη joins them: η θέση (i thési), η τάξη (i táksi). The "of" shape is της πόλης (tis pólis); in the plural the stress moves back, των πόλεων.

Neuter in -ος: το μέρος (to méros) → του μέρους, τα μέρη (ta méri). The trap is plain: -ος looks masculine, but the article gives the word away — το λάθος (to láthos), not ο λάθος (o láthos). Neuter words in -μα add a -τ- (-taf): το γράμμα (to gráma) → του γράμματος.

Masculine in -ας (-as) and -ης: ο πατέρας (o patéras) → του πατέρα (tu patéra); ο μαθητής (o mathitís) → του μαθητή, οι μαθητές. The rule throughout: look at the article, not at the ending.

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.
