What does the suffix "-ar" indicate?

The suffix "-ar" is commonly used in medical terminology and throughout other areas of vocabulary to indicate a relationship or connection to something. When you see this suffix, it typically suggests that the term refers to being "pertaining to" a particular subject or part of the body. For example, in the term "muscular," the suffix "-ar" signifies that it relates to muscles.

In contrast, the other options represent different meanings that do not align with the function of "-ar." For instance, "sharp" could relate more to terms describing sensory characteristics, while "significant" encompasses importance rather than a descriptive relationship. "Similar to" is another concept that doesn't capture the relational aspect inherent in the usage of "-ar." Understanding this could aid in deciphering various medical terms, as many utilize this suffix to clarify the connection to specific anatomical features or functions.
