The way the word sounds when spoken reminds me of the word "enunciating" "elucidate" but the definition of it is something like "to use vocabulary, syntax, and grammar in order to be powerful and persuasive in language; The act of using language persuasively". I'm looking for the word with this definition. I think the archaic definition of it MIGHT have been "a literary text that is persuasive in nature". I think it starts with an "i" or an "e" and it might have a "v" in it, but I'm not entirely sure. Please, I love this word and I want to memorize it.
