birincisini

Birincisini is a Turkish word that functions as a pronoun indicating “the first one” when it occurs as a direct object. It is formed from birinci, meaning “first,” plus the third-person possessive suffix -si and the accusative suffix -ni, yielding birincisini. The combination reflects Turkish morphology, where possessive and case markings attach to a base adjective or numeral to form a noun-like pronoun.

Morphology and form: birinci (first) + -si (3rd-person possessive) → birincisi, which adds the accusative suffix -ni to become birincisini. The resulting form is used when the speaker refers to “the first one” as the object of a verb, in contrast to birincisi (the first one) which can be used in other positions.

Usage: Birincisini is commonly used to select, identify, or reference a single item among a known set. It appears in imperatives and declarative sentences, often to emphasize choosing or identifying the first item.

Examples:

- Birincisini ver. (Give me the first one.)

- Birincisini seçelim. (Let’s choose the first one.)

- Birincisini kaybettik. (We lost the first one.)

Notes: Turkish allows multiple related forms for referring to order or specificity, such as ilk olan or birinci, but birincisini specifically marks the object form with possessive and accusative suffixes. It is widely understood in everyday Turkish and found in spoken and written contexts.
