nizinach

Nizinach is a Polish linguistic term that denotes the locative plural form of the noun nizina, which means "plain" or "flat land." It does not function as a stand-alone common noun in everyday speech, but appears in grammatical descriptions and in phrases describing location within flat landscapes.

The form nizinach is derived from nizina with the locative plural ending -ach, following standard Polish noun-grammar rules for feminine nouns ending in -ina.
