Why is the plural formation of "participle" simply formed by adding -s. The etymology of the word is Latin in origin. Would it possible end with an -I or -ae. . . or some other Latin plural ending??? Help!
Because participle is an English word but not a Latin one (unlike, say index which is both English and Latin). Participle is ultimately derived from a Latin word, (which was similar but not the same in shape), but so what?
