The verb "be speak" does not exist in English; however, if we take the word "bespeak", which means to indicate or suggest something, we can identify its antonyms. The opposite of bespeak is to conceal, hide or suppress. In other words, if one is not actively indicating or suggesting something, they may be doing the opposite by concealing or hiding their intentions. Other antonyms of bespeak include denying, rejecting and disavowing, all of which denote a lack of indication or suggestion. It's important to understand antonyms as they can help to clarify the meaning of a word and improve one's vocabulary.
