objection (n.)

late 14c., objeccioun, "argument against the validity of a proposition or line of reasoning," from Old French objeccion "reply, retort" (12c.) and directly from Late Latin obiectionem (nominative obiectio), "a throwing or putting before" (in Medieval Latin "an objection"), noun of action from past-participle stem of Latin obicere "to oppose" (see object (n.)).
