Prvom

Prvom is a grammatical form found in several South Slavic languages, including Croatian, Serbian, Bosnian, and Montenegrin. It is the locative singular form of the adjective prvi, meaning "first." In everyday usage it accompanies a noun to indicate location or ranking and typically follows prepositions such as na, u, or o. For example, na prvom mestu means "in the first place," and u prvom redu means "in the first row."

Morphology and usage: Prvom marks masculine or neuter nouns in the locative case. The feminine locative singular form is prvoj. Other cases and genders have their own forms (for example, prvi for masculine nominative, prvo for neuter nominative/accusative). The word prva or prvа may appear in different inflected forms depending on gender, number, and case, but prvo’s usage as the locative of prvi is a common pattern in phrases describing position or order.

Etymology and regional usage: The form derives from the adjective prvi, which in turn traces back to the Proto-Slavic root *prv- meaning "first." The spelling and exact usage of the locative form vary slightly across dialects, but the basic function remains consistent: to express location, rank, or emphasis in phrases linked to position, such as place or order.

Notes: Prvom is a grammatical form rather than an independent lexical item. It does not typically function as a standalone noun or a widely recognized proper noun, but rather appears within fixed expressions that denote order or spatial relationships.
