Forms

prōsecūtor m (genitive prōsecūtōris); third declension[1][2]

Etymology

It is from Latin prōsequor (“to accompany, escort”) + -tor, an agent noun.[1][3][4]

Earliest recorded meaning

The OLD defines it as one who escorts, in its quotations in an official legal capacity.[1] The TLL's earliest example is an imperial edict on papyrus, which it dates to the age of the Severi: accusers or defendants are to appear with their escorts.[3] The jurist Macer writes that provincial governors ask their colleagues to send offenders back to them with escorts.[3]

Semantic evolution

In Late Latin the prosecutores escorted gold, grain, taxes and horses for the state, as the Theodosian Code, Symmachus and Cassiodorus show,[3][4] and Sidonius uses it for companions in general.[2][5] Manuscripts often confuse it with persecūtor.[3]

In early medieval formulae it is the person who asks that a deed be entered in the municipal records; it later meant an attorney and a plaintiff.[6][7] British sources use it for an escort or supporter, for a herald's pursuivant, and for one who pursues a course of action.[8] English took it in the 1590s for one who pursues a purpose; its sense in court dates from the 1620s.[9]
