Forms

dēlēgātus m (genitive dēlēgātūs); fourth declension[1]

Etymology

It is a verbal noun of the fourth declension, from Latin dēlēgō (“to assign, delegate”) + -tus.[2][3][4]

Earliest recorded meaning

It is found in inscriptions and in the jurist Ulpian (before 223 AD),[2][4] who writes of a debtor paying a ward's creditor ex delegatu pupilli, on the ward's assignment.[2][3]

Semantic evolution

The OLD treats it as an equivalent of dēlēgātiō,[2] and the TLL glosses it as a commission or mandate: an inscription speaks of something done on the commission of the emperors (ex delegatu principum).[3] Wiktionary gives it as the financial delegation of a payment to a third party.[1]

Timeline

  • before 223 AD – Ulpian uses it of the assignment of a debt.[2][3][4]

Meanings

Noun

  1. A commission or mandate.[3]
  2. (law) Delegation of a debt: the assignment of a payment to a third party.[2][1]

Usage notes

Medieval Latin also used the participle as a noun of the second declension, dēlēgātus, -ī, “a delegate”, someone commissioned to act by a person with the power to do so;[5][4] Köbler dates it to about 1200,[4] and Du Cange has it for a delegated judge.[6]
