oczu

Oczu is the genitive plural form of the Polish noun oko, meaning "eye." It is used when the noun is in the genitive case and refers to eyes in a plural sense, as in phrases describing what belongs to or relates to the eyes.

In everyday language, occurrances of oczu appear in expressions such as ból oczu, meaning "pain of the eyes," or kolor oczu, meaning "eye color." When the eyes themselves are the subject of the sentence, Polish typically uses the nominative plural oczy rather than oczu. The noun oko has other case forms as well, with the genitive singular being oka and the genitive plural oczu.

Etymology-wise, oko originates from Proto-Slavic *oko and has cognates in other Slavic languages, such as Russian oko and Czech oko. The form oczu reflects regular Polish plural genitive morphology for neuter nouns like oko.

Usage notes include that oczu is not a standalone noun in isolation but a case form used within phrases that require the genitive. It commonly appears in medical, descriptive, or existential contexts where eye-related attributes or conditions are discussed.
