nequam

According to De Vaan, from nē- (“not”) +‎ quam (“what, whom”, f. acc. sing. quī). It may derive more directly from the adverb quam (“how”), from the same source. Traditionally derived from, and perhaps historically influenced by nē- (“not”) +‎ aequam (“equal”, f. acc. sing. aequus). Cognate with Russian ничто́жный (ničtóžnyj, “trifling, insignificant, contemptible, worthless, paltry, despicable, mean”), Russian никчёмный (nikčómnyj, “worthless, useless, good for nothing”), Russian никуды́шный (nikudýšnyj, “bad, useless, in no respect good”), all ultimately from Proto-Indo-European *ne (“not”) + Proto-Indo-European *kʷ-, with close meanings.
