Morphology

glowworm = glow + worm (transparent) = glow + worm

The sense is directly the combination of 'glow' + 'worm' and an average learner will infer 'a (small) creature that glows'.

Etymology

The word glowworm joins glow ('light') and worm ('small crawling creature'), so it simply names a little creature that shines in the dark. Today it usually means the glowing young insect or wingless adult female of some beetles, not a true worm.
