Ranked by relevance and common usage.
Keep "assertor" when the sentence already sounds natural, when a synonym would add unintended emphasis, or when readers need the most familiar wording. A synonym should clarify or sharpen the message, not simply make the sentence look more varied.
If two options seem close, choose the one that best matches the audience and purpose of the sentence.
Choose a synonym only if it keeps the core idea of "assertor" intact in the sentence you are editing.
Check whether the replacement sounds more formal, casual, emotional, technical, or forceful than the original word.
Read the full sentence after the swap. Keep the synonym only when the sentence becomes clearer or more precise.
Review note: Synonym lists are ranked with lexical data and reviewed for practical writing value. Use the comparison notes, sentence evidence, and source labels together; a high-ranking synonym can still be wrong when the audience, register, or grammar changes.
After choosing a replacement for "assertor", read the sentence once for meaning and once for rhythm. The best synonym should feel natural in the full sentence, not only accurate in a word list.
If the synonym makes the sentence slower, vaguer, or more dramatic than intended, keep "assertor" or choose a simpler alternative from the closest-match group.

2017 Mario von der Ruhr, et al: Religion and Wittgenstein's Legacy; →ISBN When Wittgenstein says that he cannot contradict the assertor of a Last Judgement, he uses (repeatedly) the first person singular. There is no argument that the impossibility of his contradicting the man is a result of his not himself being a religious man, or not being a participant in any religious life, the result, that is, of some condition such that, if anyone were in that condition, he also would not be able to contradict the assertor. He mentions the case of an atheist who does contradict the assertor, and asks whether the atheist means the same by a Last Judgement as does the assertor, but replies that the criterion for meaning the same isn't clear.
