The suffix -oid is used to describe something that is what?

The suffix -oid is utilized in medical terminology to indicate resemblance or likeness to something. This is commonly seen in terms such as "humanoid," which describes something that resembles a human. The use of this suffix helps convey the idea that one thing shares characteristics or features similar to another, making it an important component in medical language for describing conditions, anatomical structures, or pathologies that bear similarities to other entities.

While the other options describe different concepts—condition of (often related to medical states), study of (as in the field of research), and record (as seen in medical documentation)—they do not align with the meaning conveyed by the suffix -oid. Thus, "like, resembling" is the most accurate choice for the definition of this suffix.
