Morphology

quasiparticle = particle (semi-transparent) = quasi + particle

Formally 'quasi-' + 'particle' yields 'particle-like', but the term is a technical physics concept that may not be obvious to general learners.

Etymology

Quasiparticle comes from the parts quasi- meaning 'almost' and particle, so it means 'almost a particle'. In physics, a quasiparticle is something inside a material that behaves like a real particle, which is why scientists use that name.
