Morphology

particle = part (semi-transparent) = part + icle

The computing/graphics sense extends the basic 'small piece' meaning into a technical domain, so learners may relate it to 'part' but the domain-specific usage requires experience.

Etymology

Particle comes from the Latin particula, which means 'small part' and is the same root as part. In computer graphics a particle is a tiny 'piece' used in large numbers to make effects like smoke, fire, or sparks.
