Say what something isn't
じゃありません is the polite negative of です — "is not" instead of "is".
JLPTN5
Noun/Adjective + じゃありません
Swap です for じゃありません at the end of an X は Y sentence to say "X is not Y." Nothing else in the sentence changes — same topic marker は, same word order, just the ending flips from affirmative to negative.
