Pronunciation

  • Classical: [deː.riːˈwaː.ti.oː][1]
  • Ecclesiastical: [de.riˈvat.t͡si.o][1]

Forms

dērīvātiō f (genitive dērīvātiōnis); third declension[1]

Etymology

It is formed from Latin dērīvō + -tiō, from the verb meaning “to divert”.[2][1][3] dērīvō is made from rīvus (“stream”),[4] which de Vaan traces back to Proto-Italic *rīwo- (“stream”) and Proto-Indo-European *h₃riH-uo- (“whirling”).[4]

Earliest recorded meaning

It is found from Cicero (81–43 BC) on,[3][5] who speaks of the leading off of rivers (derivationes fluminum) in De officiis.[2][6]

Semantic evolution

Livy uses it for the customary drawing off of the water of the Alban lake,[3][6] and it could also name a branch pipe.[2] Quintilian applied it to a shift of sense, when one calls the rash man brave or the prodigal generous.[2] The derivation of words, its grammatical sense, is reported from Pliny by Servius.[2]

In medieval Latin it meant a drawing off of fluids in medicine, an origin or descent, an interpretation, and the etymological derivation of a word;[7] British sources also use it for an overflow of waters.[8] English borrowed it as derivation in the early 15th century, first in the medical sense “a drawing off”, from French and directly from Latin.[9]
