Morphology

neutron = neutral (semi-transparent) = neutr + on

The meaning 'neutral particle' is predictable from 'neutral', but the suffix '-on' is a technical particle-forming element and the specific scientific sense requires domain knowledge.

Etymology

The word neutron comes from the Latin word neuter, meaning 'neither', because the particle has 'no' electric charge and is neither 'positive' nor 'negative'. The ending -on is the same as in electron and proton, so the name helps you remember it is one of the basic particles in an atom.
