  • In the sentence 'He picked up the book and put it back on the shelf', the word 'back' is an example of an adverbial particle that modifies the verb.

  • The idea was to have users freely explore the topics of particle physics.

    Academic text (2006)
  • Back is an adverbial particle, so that gets more stressed.

  • Colleagues gather to discuss high-energy nuclear and particle physics at a 1955 conference in Rochester, New York.

    Academic text (2005)
  • When studying English phrasal verbs, it is important to understand how particles like 'out' and 'in' affect the verbs they accompany.

Morphology

particle = part (opaque) = part + icle

The grammatical sense 'a small function word' is a specialized linguistic meaning and cannot be straightforwardly derived by learners from 'part' + '-icle'.

Etymology

Particle comes from the Latin particula, meaning 'small part', and it shares the same root as the word part. In grammar a particle is a very small 'part' of a sentence (like 'up' in 'give up') that helps change the verb's meaning.
