Pronunciation

  • IPA (Classical): [deːˈfiː.ni.oː][1]

Forms

dēfīniō (present infinitive dēfīnīre, perfect active dēfīnīvī, supine dēfīnītum); fourth conjugation[1]

Etymology

It is from dē- and fīniō “to bound, limit”, from fīnis “boundary”.[2][1][3]

Earliest recorded meaning

The OLD's first citation is Plautus, of settling something.[2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant to fix the limits of, bound, as Cicero's olive trees marking the end of an estate, to limit, restrict, and to put an end to, as in Cicero.[2][5] It meant to determine, settle, as in Plautus, to ordain for someone, to define, describe exactly, as in Cicero, and to specify.[2] In law it meant to assert, as in Ulpian, and to lay down a rule.[2] Lewis and Short call it frequent in Cicero.[6]

In Ecclesiastical Latin it meant to solve, define, determine, limit.[7] Italian definire and Spanish definir are borrowings.[1] English define came through Old French in the late 14th century, and English definition from dēfīnītiō.[3]
