To 'forswear' a belief means to formally reject or disavow it. The term is derived from the combination of "for-" and "swear," indicating a serious and deliberate decision to renounce a belief or commitment. When someone forswears a belief, they are actively choosing to distance themselves from it and are often making a public declaration of that decision. This change in stance signifies a strong intention not only to abandon the belief but also to distance oneself from its associated values or practices. The choice captures the essence of the term, emphasizing the act of formally turning away from something previously accepted or held.
