Intermediating means acting as a mediator or an intermediary between two parties. Antonyms, on the other hand, are words that have opposite meanings to the original word. Some antonyms for intermediating could be antagonizing, opposing, conflicting or hindering. These words signify a direct conflict or lack of cooperation between two parties, rather than someone reconciling the differences. While intermediating often refers to bridging gaps and overcoming differences, antonyms suggest a lack of willingness or ability to do so. It's important to understand the nuance between these words and use them appropriately, as they can have a significant impact on the tone of communication.
