  • Neutrinos are ghostly subatomic particles that interact weakly with matter and travel at virtually the speed of light.

Both events are equally likely, and it's through probabilities that we explain this behaviour of subatomic particles.

Morphology

subatomic + particle

The meaning 'a particle smaller than an atom' is directly derivable from combining 'subatomic' (below/within the atom) with 'particle' (a tiny piece). This is a regular noun phrase formed by transparent morphological and semantic composition, so a B1 learner who knows the constituents can readily infer the MWE's meaning.

Etymology

Subatomic particle comes from the parts sub-, meaning 'under', and atomic, so it creates the image of a tiny particle below an atom. That's why it means 'a particle smaller than an atom'.
