- particle (n.) late 14c., "small part or division of a whole, minute portion of matter," from Latin particula "little bit or part, grain, jot," diminutive of pars (genitive partis) "a part, piece, division" (from PIE root *pere-(2) "to grant, allot"). Particle physics attested from 1969. In construction, particle board (1957) is so called because it is made from chips and shavings of wood.
