Morphology

quicklime = quick + lime (semi-transparent) = quick + lime

The components 'quick' and 'lime' are clear, but the specific meaning of 'quicklime' as calcium oxide is specialized and not directly derivable from the components.

Etymology

Quicklime combines quick and lime. Here quick does not mean 'fast' but an old word for 'alive', because when you add water the lime seems to 'come alive', hissing and giving off heat, which is why people called it quicklime.
