When we hear the words "setting free", we may think of freedom, letting go or liberating someone or something from constraints. However, there are several antonyms that convey the opposite meaning. Words like confine, imprison, captivate, restrict or detain can all serve as antonyms for the phrase. These words imply that an individual or thing is being restrained, held back or kept in a controlled state. Setting free can be seen as an act of kindness or mercy, while the opposite can be viewed as an act of oppression or injustice. It is important to understand the various meanings and implications of words to communicate effectively and accurately.
