By surface analysis, co- + adjutor. The French derivation gave the accentuation co⁠ˈadjutor (used by Samuel Taylor Coleridge), but the poets generally, since 1600, appear to have coa⁠ˈdjutor, after Latin. No Latin *coadiuvō or *coadiūtō is recorded, but in the modern languages words have been formed on these types, suggested by coadjutor.
