Piór

Piór is the genitive plural form of the Polish noun pióro, which means feather or quill. As a grammatical form, piór does not stand as an independent word with a meaning of its own; it functions to mark the genitive plural in phrases referring to feathers.

In typical usage, piór appears in contexts that express possession, quantity, or description of feathers. Examples include phrases like "kolor piór" (color of feathers) and "liczba piór" (number of feathers). The form is most common in written Polish and in grammatical or descriptive contexts where the genitive plural is required.

Etymology and related forms: pióro is a longstanding Polish noun with cognates in related Slavic languages. Its stem and inflected forms have remained relatively stable over time, with piór serving as the genitive plural counterpart to the nominative plural pióra.

Notes: Because piór is a grammatical form rather than a standalone lexical item, it is primarily encountered in dictionaries, grammar descriptions, and formal prose. In everyday speech, speakers typically rely on the base noun and rearrange sentence structure to avoid less common inflected forms when necessary.
