nie
Nie is primarily known as the negation particle in Polish. It precedes the word or phrase it negates and is used with verbs, adjectives, adverbs, and nouns in a wide range of constructions. Examples include Nie wiem (I don’t know), To nieprawda (That is not true), and Nie mam czasu (I don’t have time). In questions, nie can appear for emphasis or in idiomatic forms such as Czy to nieprawda? (Isn’t that true?).
Etymology and function: The Polish nie is a basic negative marker descended from Proto-Slavic negation elements.
Other uses: Beyond Polish, the sequence Nie occurs in other languages as part of names or transliteration.
