What is the etymology of antecedent?

The etymology of etymology is from the greek etumologia which means "true sense of a word"

An antecedent is the noun (or nouns) to which a pronoun refers, to avoid repetition of the same noun or noun phrase.

The antecedent for the pronoun you is the name of the person or people that is or are being spoken to; the pronoun you is the second person, singular or plural. Example sentence: John and Linda, you...

it depends who he is, if you capitalized he for a reason then it is probably god because tipically when refering to god in a pronoun form it is capitalized

Etymology is the study of words and their origins and development.
