niepoprawne

Niepoprawne is a Polish adjective formed with the negation prefix nie- attached to poprawny, meaning not correct or not proper. The word functions as the standard negated form of opisujący to "correct" or "proper," and is commonly used to label things that deviate from accepted standards, correctness, or propriety. The prefix nie- is integrated into the lemma, so the basic form is spelled as a single word: niepoprawny.

In terms of grammar, niepoprawny inflects like a typical Polish adjective. Singular masculine: niepoprawny; singular feminine: niepoprawna; singular neuter: niepoprawne. Plural forms include niepoprawni for masculine personal nouns, and niepoprawne for feminine and neuter nouns or for mixed groups. The form niepoprawne can also be used as a plural modifier before plural nouns of various genders (e.g., niepoprawne dane, niepoprawne odpowiedzi).

Usage and nuance: niepoprawne is applied to statements, data, behavior, procedures, or materials that fail to meet expected standards of accuracy, legality, or propriety.
