Pronunciation

  • IPA: /ˌpɹɒs.ɪˈkjuː.ʃən/ (UK); /ˌpɹɑ.sɪˈkju.ʃən/, /ˌpɹɒs.ɪˈkju.ʃən/ (US)[1]

Etymology

It is borrowed from French prosecution (late 13th century) and directly from Late Latin prōsecūtiō, prōsecūtiōnem, a following, continuation, retinue,[2][3] from prōsecūtus, past participle of prōsequī, to follow after, pursue, attack (see prosecute).[2][4]

Earliest recorded meaning

The carrying out or following up of anything: 1567 in the OED, the 1560s in Etymonline;[5][2] the effort to obtain a property or benefice from 1564.[5]

Semantic evolution

A literal pursuit or chase (1567) is obsolete.[5][2] The carrying on of an occupation is from 1631.[5] The legal sense, the institution and carrying out of a suit at law, is from the 1630s,[2] and hence the party who brings the proceedings from 1891.[2]
