Geceyi

Geceyi is the accusative form of the Turkish noun gece, meaning "the night." In Turkish, the accusative marks a definite direct object of a verb, and when a noun ends in a vowel, a linking consonant y is added before the suffix. The result for gece is geceyi, indicating “the night” as a specific object in a sentence.

This form is commonly used with verbs that describe spending or experiencing the night. For example, geceyi evde geçirdik means "we spent the night at home," and geceyi uyumadan geçirdim can be rendered as "I stayed up all night." The accusative suffix -yi (subject to vowel harmony) conveys definiteness and is often used in contexts where the object is known or clearly identified.

Geceyi appears in everyday Turkish as well as in literature and media where the night is treated as a concrete, referable entity. It is part of a broader system of Turkish noun cases, which include different suffixes to indicate objects, possession, and other grammatical relations, without the use of definite or indefinite articles found in some other languages.

In summary, geceyi is not a separate lexical item beyond its grammatical role; it is the defined direct object form of gece used to specify "the night" as the object of a verb.
