The word "interceded" refers to the act of intervening or mediating on behalf of someone else. Antonyms for this word might include "ignored," "neglected," or "abandoned," which would describe situations where no intervention or mediation took place. Other antonyms might include "escalated," "aggravated," or "worsened," which would describe situations where someone made the situation worse instead of intervening to improve it. Alternatively, "agreed," "concurred," or "approved" might be seen as antonyms if the opposite of interceding is not taking action on behalf of someone but instead simply agreeing with their choices or decisions.
