Morphology

butyl = butane (semi-transparent) = but + yl

Formed by the chemical suffix '-yl' from butane; the relation is regular in chemistry but requires technical knowledge.

Etymology

Butyl comes from the root butyr-, which means 'butter' and is the same root in butter and butane. Early chemists found related substances in butter, so the name stayed, and today butyl means a part of a molecule made of four carbon atoms, used in many plastics and fuels.
