- wrath, wrathful, wrothWrath is an archaic or literary noun meaning ‘anger’, and is pronounced rawth or roth, or in AmE rath. Wrathful is the corresponding adjective meaning ‘angry’. Wroth is also an adjective, and is always used predicatively, i.e. after a verb, especially in the expression wax wroth meaning ‘to become angry’. As these words move further back into the remoteness of archaism, their distinctions are becoming blurred, with wroth in particular being used where wrath is needed.
