Origin of antecedent
late 14c. (n. and adj.), from Old French antecedent (14c.) or directly from Latin antecedentem (nominative antecedens), present participle of antecedere "go before, precede," from ante- "before" (see ante) + cedere "to yield" (see cede). Used as a noun in Latin philosophical writings.
