Pronunciation

Forms

ūsūrpō (present infinitive ūsūrpāre, perfect active ūsūrpāvī, supine ūsūrpātum); first conjugation[1]

Etymology

It is from ⟨*ūsūripō⟩, from ūsus “use” and rapiō “to seize”, so “to seize for one's use”.[2][1][3][4] De Vaan traces ⟨ūtor⟩, the base of ⟨ūsus⟩, to Proto-Italic ⟨*oit-e/o-⟩ “to use”, perhaps Proto-Indo-European *h₃eyt- (“to take along”), and ⟨rapiō⟩ to Proto-Indo-European *h₁rp-i-.[5]

Earliest recorded meaning

The OLD's earliest citations are Ennius, of using a word, and Plautus, of practising and of perceiving.[2] Köbler dates Ennius 204–169 BC and Plautus c. 250–184 BC.[6]

Semantic evolution

It meant to put into practice, perform regularly, and to make habitual use of, employ, as in Plautus; to use a word or name, as in Ennius and Cicero; with oculīs or auribus to perceive; and in Cicero to take possession of property on one's own initiative without strict legal title, and to assert a right by exercising it.[2][4]

In Ecclesiastical Latin it means to usurp, make use of, assert a right, take possession of, seize wrongfully.[7] English usurp (early 14th century) is from it through Old French.[8]
