Morphology

heavy-duty = heavy + duty (transparent) = heavy + duty

The adjective is a straightforward compound of 'heavy' + 'duty' meaning 'suitable for heavy/arduous work', which learners who know the components can infer.

Etymology

Heavy-duty comes from putting together heavy meaning 'large or strong' and duty meaning 'a task or job', so it was used for things for 'serious work'. That's why heavy-duty now describes tools, machines, or clothing made to stand up to hard use.
