Morphology

half-hour = half + hour (transparent) = half + hour

The meaning is directly compositional: 'half' + 'hour' = a period of thirty minutes, which learners can derive.

Etymology

Half-hour is simply two parts: half, meaning 'one of two equal parts', and hour, meaning 'sixty minutes'. So a half-hour is 'half' of an hour, which is 30 minutes.
