trzecia

Trzecia is a term used in Polish to denote the feminine singular form of the ordinal number “third.” It functions as an adjective that agrees with a feminine noun and is used to designate the third item in a sequence. For example, in expressions like “trzecia strona” (the third page or side) or “trzecia osoba” (the third person), trzecia modifies the noun to indicate order. Like other Polish ordinals, trzecia inflects for case and number; in nominative singular feminine it is “trzecia,” while the genitive is “trzeciej,” the dative “trzeciej,” and the accusative “trzecią.” The masculine and neuter forms are “trzeci” and “trzecie,” respectively. The word shares its etymology with other numerals derived from “trzy” (three).

In toponymy and other proper names, the element “trzecia” may appear in compound place names or descriptors indicating historical order or segmentation, but it is not a common standalone name outside specific contexts. The term is primarily used in Polish-language texts and is unlikely to appear in isolation in other languages, though similar ordinal constructions exist in other Slavic languages.
