Vrstama

Vrstama is the instrumental plural form of the feminine Slavic noun vrsta, meaning "kind," "type," or "category." In Croatian, Serbian, and Bosnian, vrstama is used primarily in constructions that express grouping by kinds or distributing items across categories. A common usage is with the preposition po, as in razvrstati po vrstama, meaning "to sort by kinds," or rasporediti po vrstama, meaning "to allocate by categories."

Etymology and morphology: vrsta derives from Proto-Slavic vrsta, with cognates across related languages. The instrumental plural ending -ama marks the grammatical case and number, producing vrstama for feminine nouns in the instrumental plural. This form appears when the action concerns organizing or classifying things according to type.

Function and usage: Vrstama appears mainly in technical, statistical, or cataloging language where a criterion is defined by type. It is not typically used as a standalone noun in ordinary conversation; rather, it occurs in phrases describing methodology, classification, or analysis, such as organizing data "by kinds" or items "by categories."
