Which suffix indicates something that is pertaining to?

The suffix that indicates something that is pertaining to is -ory. This suffix is commonly used in medical terminology to describe a relationship or relevance to a particular process, condition, or substance. For example, in words like "auditory," which relates to hearing, and "respiratory," which pertains to breathing, the suffix -ory helps to form adjectives that describe their connection to specific functionalities or characteristics.

The other suffixes serve different purposes in the context of medical terminology. The suffix -oid means "like" or "resembling," often used to suggest similarity rather than a direct relationship. The suffix -oma typically refers to tumors or conditions characterized by swelling, and -ole is a diminutive suffix indicating something small, often used in anatomical terms. Understanding these distinctions helps in deciphering medical terms and their meanings effectively.
