The term "inter mutual" describes a relationship or situation where two or more parties mutually benefit from each other's actions. Some antonyms for this term include "unilateral," which indicates a situation where only one party benefits, and "nonreciprocal," which means that the actions or benefits are not mutual. Other antonyms for "inter mutual" include "one-sided," "unequal," and "asymmetrical," which all imply a lack of balance or equality in the relationship. In some cases, the opposite of "inter mutual" could also be described as "competitive" or "adversarial," where the parties involved are in opposition to each other rather than working together to achieve mutual benefits.
