‘也不’ (yě bù) is a conjunction meaning 'neither' or 'nor', used to express the negative counterpart of a previously stated or implied negative condition. It combines the adverb 也 (yě, 'also, too') with the negator 不 (bù, 'not'), forming a correlative structure that reinforces shared negation across two or more items, clauses, or people. Unlike standalone 不, 也不 always appears in context — typically after another negative statement — and signals that the same negative situation applies to an additional subject or action.

This expression is common in spoken and written Chinese for listing parallel negatives, especially in daily conversations about preferences, abilities, or habits. It often follows phrases like ‘我不会...’ (I can’t...) or ‘他没去...’ (He didn’t go...), then introduces a second negative clause: ‘他也不会...’ → ‘他也不会，我也不...’. While it looks like a noun phrase, 也不 functions strictly as a conjunction linking negative ideas, not as a standalone noun or pronoun.
