Morphology

gluon = glue (semi-transparent) = glue + on

The coinage evokes 'glue' plus the particle-forming suffix '-on'; the metaphor is understandable but the precise scientific meaning requires domain knowledge.

Etymology

The word gluon comes from the English word glue, meaning 'to stick', and the common particle ending -on, as in electron and proton. So a gluon is a 'glue' particle that holds tiny building blocks called quarks together inside protons and neutrons.
