Remark refers to a spoken or written comment made to express an opinion, observation or reaction. Some antonyms for this word include keeping quiet, silence or non-response. Holding back from making any comments may be appropriate in certain situations, such as when one is unsure of the facts. Alternatively, silence may be the best response to avoid conflict or negative consequences. Other antonyms for remark may include censure, criticize or condemn, which indicate a negative evaluation of someone's words or actions. Conversely, praise, applaud or commend may represent a positive comment or endorsement.
