The concept of transacting is one that involves exchanging goods, services or ideas between two parties. In order to understand an antonym for "trans acting," it's important to think about words that represent the opposite of this process. One possible antonym could be "unilateral," which refers to decisions or actions made by only one party without the consultation or involvement of the other. Another antonym could be "passive," which suggests that one party is not actively engaging or participating in the exchange, but rather simply receiving or observing. Finally, a third antonym could be "reclusive," which implies that one party is intentionally avoiding or withdrawing from any sort of exchange or interaction with others.
