Which suffix denotes an act, manner, or doctrine?

1. -ion

2. -ist

3. -ism

4. -ity

The correct answer is: -ism

The suffix that denotes an act, manner, or doctrine is indeed -ism. This suffix is commonly used to form nouns that describe a specific system, practice, or philosophy. For example, in terms like "capitalism," "realism," or "optimism," the suffix signifies an overarching belief system or doctrine associated with certain behaviors or practices. Other suffixes such as -ion typically indicate a process or result of an action, as in "creation," while -ist generally refers to a person who adheres to a particular doctrine or belief, as seen in "artist" or "feminist." The suffix -ity often denotes a state or quality, evident in words like "clarity" or "ability." Thus, -ism distinctly highlights a set of beliefs or practices, making it the appropriate choice for this question.
