Morphology

avgas = aviation + gas (semi-transparent) = av + gas

Formed by clipping/blending of 'aviation' (av) + 'gas'; the technical abbreviation 'av' is not fully obvious to average learners.

Etymology

The word avgas is a short form of aviation and gasoline, so you can think of 'av' + 'gas' as 'plane fuel'. So avgas means the special gasoline used in aircraft with piston engines.
