What does the suffix "-oid" imply in medical terms?

The suffix "-oid" in medical terminology implies "resembling" or "like." This suffix is commonly used in a variety of terms to indicate that one thing has a likeness or similarity to another. For instance, in the term "hypochondriac," the "-oid" part suggests a resemblance to the condition of being overly concerned about health.

In contrast, the other choices represent different meanings that do not align with the function of "-oid." "Pertaining to" typically corresponds to the suffix "-al" or "-ic," indicating a relationship to an associated term. "Reproducing" would be more closely tied to terms that include other specific suffixes such as "-gen" or "-gonic." Lastly, "controlling" is indicated by suffixes like "-stasis" or "-regulatory." Understanding these distinctions helps clarify the specific meaning conveyed by various medical suffixes.
