Question

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

Explanation:

To determine the meaning of the suffix -ist in "optimist", we analyze the context. An optimist is someone who believes in a positive outlook. The suffix -ist often denotes a person who does or believes something (e.g., "scientist" - one who studies science, "pessimist" - one who believes in the worst). The other options don't fit: "shows a trait" is not accurate, "imagination/vision" doesn't relate, and "fights conviction" is incorrect.

Answer:

one who does or believes something
