Disengage refers to the act of withdrawing or detaching oneself from a situation or interaction. Its opposite or antonym, therefore, would be words or phrases that convey the opposite meaning, such as engage, involve, connect, commit, or participate. These words imply a willingness to take part in something or to become more involved in a situation. For instance, if someone disengages from a conversation, an antonym for that would be to engage in the conversation. Similarly, if someone disengages from a project, the antonyms can be to involve, commit, or participate in it. The opposite of disengage is all about a person's active participation and involvement in a situation.
