Morphology

tankless = tank (transparent) = tank + less

The adjective is a straightforward negative/privative formation from 'tank' + '-less' meaning 'without a tank', which learners can readily infer.

Etymology

Tankless comes from the simple parts tank meaning 'large container' and -less meaning 'without'. So a tankless water heater has no tank and makes hot water only when you need it.
