Günü

Günü is a Turkish word that represents a form of the noun gün, meaning "day." In Turkish, gün can refer to a calendar day as well as daylight, and it serves as a base for a range of inflected forms used to express grammatical relations in a sentence.

In Turkish grammar, günü specifically appears as the accusative form of gün, used when the day is the direct object of a verb. Other inflected forms include günün (genitive: "of the day"), güne (dative: "to/for the day"), and günde (locative: "in/at/on the day"). The phrase günün sonunda is a common collocation meaning "at the end of the day," illustrating how the word functions in time-related expressions. The idiom günü kurtarmak, literally "to save the day," is another widely used construction.

Etymologically, gün derives from a common Turkic root for day, with cognates in other Turkic languages such as Azerbaijani gün. These forms reflect a shared lexical core across Turkic languages, adapted through suffixal inflection in Turkish to indicate case and grammatical role.

As a proper noun, Günü can occur as a Turkish surname, though it is primarily a common noun in everyday language. In general use, the term appears across timekeeping, calendars, literature, and daily speech, where it helps specify time and sequence.
