What is the closest synonym for "incompatible" used to describe partners?

The term "incompatible" refers to a lack of harmony or ability to coexist effectively, particularly in relationships such as partnerships. "Conflicting" is the closest synonym in this context, as it indicates a situation where partners have opposing views, interests, or behaviors that can lead to discord and an inability to work cohesively.

The other options do not align with the meaning of "incompatible." "Agreeable" suggests a sense of harmony and compatibility, indicating that the partners are suited to each other. "Friendly" implies a positive and amicable relationship, which is contrary to the idea of being incompatible. "Compliant" refers to a willingness to conform or agree, which also does not capture the essence of two partners being incompatible. Therefore, "conflicting" is the most accurate synonym, reflecting the inherent disagreement or lack of suitability between partners.
