The word "no-no's" refers to things that are forbidden or considered unacceptable. The antonyms for this term can be etiquette, allowance, or approval. Etiquette refers to the customary code of polite behavior in society, whereas allowance means that something is allowed or permitted. Approval, on the other hand, means the endorsement or agreement with something. All these antonyms contrast with "no-no's" as they signify acceptance, permissibility or praise towards something, rather than censure. It is important to recognize these antonyms to understand the full spectrum of acceptability in different contexts, and when to adhere to social norms.
