Ranked by relevance and common usage.
Keep "plurisecular" 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 "plurisecular" 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 "plurisecular", 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 "plurisecular" or choose a simpler alternative from the closest-match group.

Rather than seeing in [the anonymous author of My Secret Life] a courageous fugitive from a "Victorianism" that would have compelled him to silence, I am inclined to think that, in an epoch dominated by (highly prolix) directives enjoining discretion and modesty, he was the most direct and in a way the most naïve representative of a plurisecular injunction to talk about sex.

...it is convenient to take into consideration, on one hand, registration in a program within a plurisecular story of academic mobilities and of the literary imagination linked to the juvenile journey and, on the other hand, the contribution of ERASMUS journeys to a socialisation centered on the meeting of individuals from different European countries.
