dokuzuncu

Dokuzuncu is a Turkish ordinal adjective meaning nineteenth. It is formed from the cardinal number dokuz (nine) plus the ordinal suffix -uncu, following Turkish vowel harmony. As with other Turkish ordinals, dokuzuncu serves to indicate position in a sequence and remains grammatically an adjective.

In usage, dokuzuncu functions before the noun it modifies, and the noun bears any required case endings. For example, dokuzuncu gün means the nineteenth day, and dokuzuncu bölüm means the nineteenth chapter. Turkish ordinals do not change for gender; they decline only through the noun they accompany.

Dokuzuncu can appear in a range of contexts where order or ranking is described, such as lists, chapters, events, or positions. It may be combined with other numeric expressions to form larger dates or sequence references, for instance in compound forms like on dokuzuncu yüzyıl to denote the nineteenth century, where dokuzuncu is part of a larger ordinal construction.

Etymologically, dokuzuncu illustrates the standard Turkish pattern of forming ordinals from cardinal numbers with the appropriate ordinal suffix, adjusted to vowel harmony. It is one of several ordinal forms used in Turkish to enumerate items, steps, or periods in a sequence.
