Morphology

flywheel = fly + wheel (semi-transparent) = fly + wheel

The components 'fly' and 'wheel' are recognisable, but the specialised mechanical meaning 'heavy wheel that stores rotational energy' is not directly deducible by all learners from the parts alone.

Etymology

Flywheel comes from the parts fly and wheel. It is a heavy wheel that 'spins' fast to store energy and help a machine keep a steady speed, so the name shows it keeps the machine running smoothly.
