Interceding refers to the act of mediating or intervening between two parties. The antonym of interceding is "ignoring" which means to disregard or overlook. When one ignores a matter, they choose not to get involved or intervene. Another antonym for interceding is "aggravating" which means to make a situation worse or more severe. When someone aggravates a situation, they are not helping to mediate or resolve it; instead, they are making matters worse. Lastly, "abetting" can also be an antonym for interceding, which refers to aiding or encouraging someone in a wrongdoing. In this case, they are not intervening to stop the wrongdoing but rather supporting it.
