What is the meaning of the word incompatible?

The term "incompatible" describes a situation where two or more elements cannot coexist or function together harmoniously due to fundamental differences. Therefore, the meaning of "incompatible" is closely aligned with the idea of "conflicting," as both terms imply that there's an opposition or lack of agreement between the elements in question.

For instance, when two ideas or objects are described as incompatible, it means that they have characteristics or qualities that prevent them from working together effectively. This can apply in a variety of contexts, such as incompatible technologies, perspectives, or even relationships.

The other words do not convey this same sense of opposition or inability to coexist. "Subsequent" refers to something that follows after a previous event, "relevant" indicates a relationship to the subject at hand, and "suitable" means appropriate or fitting. These meanings do not capture the essence of conflict inherent in "incompatible."
