The term "give word" means to promise or make a commitment. The opposite or antonyms of this phrase could be to deny, break a promise, or withdraw a commitment. When we say we will do something, we are giving our word and therefore creating an expectation in others. If we fail to meet that expectation, we are essentially breaking our promise, which can lead to mistrust and damaged relationships. It is important to be mindful of our commitments and only give our word when we are certain that we can deliver on it. Otherwise, it is better to avoid making any promises or commitments altogether.
