What does the suffix -OID mean?

• A. Resembling
• B. Disease
• C. Tumor
• D. Break

Answer: (A)

The suffix -oid means resembling or like. In medical terms, it’s used to show that something has a form or character similar to what the base word describes. For example, humanoid means human-like, asteroid means star-like, and spheroid means sphere-shaped. So this ending is all about likeness, not about being a disease, a tumor, or something that involves breaking. Those ideas would come from other word parts: disease or inflammation would use endings like -itis or -osis, tumor is often -oma, and a breaking action would use different roots or suffixes such as -clasia or -lysis.
