The suffix -ion denotes which meaning?

• A. Process
• B. Pertaining to
• C. Abnormal condition
• D. Condition of

Answer: (A)

The suffix -ion signals an action, process, or the result of an action. It turns a verb into a noun that names what is being done or what comes from the action. For example, analyze becomes analysis—the act and result of analyzing; inform becomes information—the data or content produced by informing. In medical terms, -ion helps name processes or states, like infection (the process of infecting) or circulation (the act of circulating). Among the options, the meaning that fits best is “Process.” The others describe adjectives or specific types of conditions, which are not what -ion typically conveys: indicating “pertaining to” is usually shown by different suffixes, while “abnormal condition” or “condition of” involve other endings that denote disease states or relationships rather than the action or result of an action.
