Question

what does the suffix -ist mean in the word optimist? among the three sisters, the optimist had the brightest outlook. one who fights conviction or principle one who does or believes something one who shows a trait or ability one who has imagination or inner vision

Explanation:

To determine the meaning of the suffix “-ist” in “optimist”, we analyze the context and the meaning of “optimist”. An optimist is a person who believes in a positive outlook. The suffix “-ist” generally denotes a person who does or believes something (e.g., “scientist” is one who studies science, “pessimist” is one who believes in a negative outlook). The other options don't fit: “one who fights conviction or principle” is incorrect (no fighting implied), “one who shows a trait or ability” is not the main meaning of “-ist” here, and “one who has imagination or inner vision” doesn't relate to “optimist”.

Answer:

one who does or believes something
