Word Root of particle
The Latin word pars, meaning “part,” and its form partis give us the root part. Words from the Latin pars have something to do with a part, section, or portion. To participate is to take part in some activity. Anything partial involves only part of something. A particle is a tiny bit or portion of something. It is easy to see that part itself also comes directly from pars in both form and meaning.
