✅ Subject is the best word to refer broadly to something under discussion or exploration (the subject of the conference; the subject of the essay).

✅ Subject and topic can be used interchangeably to refer to the main thing being discussed or explored.

✅ Topic can also be more narrow than subject, referring to a specific area of the subject that can be treated in its own section (In the book on immigration, the topic of the chapter was economic influences).

✅ Succeed means to achieve one's goals in life (He was determined to succeed).

✅ Succeed can also be used to refer to achieving goals or doing well, even if those goals don’t match society’s idea of what you should achieve (He succeeded in his ambition to be a good puzzle solver).

✅ Prosper is the best word to refer to achieving material success (She’ll prosper with a job that she loves).

✅ Prosper can also be used to refer to doing well emotionally, and feeling good in your life (They really prospered once they left their stressful job).

We’re sure you’ll prosper with these synonyms.

✅ Belief is the best word to refer to an acceptance that something is right or true, without immediate proof (They had complete belief in his story).

✅ Certainty is the best word to refer to a strong internal conviction that something is right or true, also without necessarily needing proof (In his mind, it was a certainty that the earth is flat).

✅ Belief is a more general word, whereas certainty implies a stronger conviction (a belief in the goodness of people; It’s a certainty that I annoy her).

✅ That doesn’t mean that a certainty is necessarily more likely to be true than belief. The difference between the two words comes down to a lack of doubt: certainty suggests that there’s no doubt in your mind at all, whereas belief is slightly more neutral.
