Morphology

megacycle = cycle (semi-transparent) = mega + cycle

The meaning is compositionally derived from 'mega-' meaning 'million' plus 'cycle', but the technical unit sense may not be immediately familiar to learners.

Etymology

Megacycle comes from the parts mega- and cycle. The mega- part means 'large' and in measurement it means 'a million', and cycle means 'a single turn or wave', like in bicycle where it means 'wheel'. So, a megacycle is 'a million cycles per second', which is why radios and electronics used this unit.
