antibaryon singular

Morphology

antibaryon = baryon (semi-transparent) = anti + baryon

The word is transparently built from anti- + baryon, but the technical sense 'antiparticle counterpart' is specialized and not fully predictable for a learner without scientific context.

Etymology

Antibaryon combines the prefix anti- meaning 'opposite' and baryon from a Greek word for 'heavy'. So an antibaryon is the particle that is the 'opposite' of a baryon, which matches its role as the antiparticle with the opposite baryon number.
