Morphology

luminaire = lumen (semi-transparent) = lumin + aire

The 'lumin-' element meaning 'light' can be recognized by learners familiar with words like 'lumen' or 'luminous', but the French-derived suffix '-aire' and the technical usage make the formation only partly inferable.

Etymology

Luminaire comes from French for a light fitting and from Latin lumen, meaning 'light'. A helpful way to remember it is to think of illuminate or luminous—a luminaire is simply a complete unit that gives or directs 'light'.
