The concept of disowning implies denying or rejecting ownership or association with someone or something. The opposite of disowning is to claim or take ownership of something or someone, which can be described by antonyms such as acknowledge, accept, embrace, or adopt. To acknowledge means to recognize or admit the existence, importance, or value of something or someone. Accepting implies taking responsibility, approving, or agreeing to something or someone. Embracing means to welcome or accept something wholeheartedly, while adoption denotes the act of legally or emotionally accepting a child or idea as one's own. All of these antonyms present favorable and affirmative actions that contrast with disowning's negative and dismissive connotations.
