Forms
auxilior (present infinitive auxiliārī or auxiliārier, perfect active auxiliātus sum); first conjugation, deponent[1] An active auxiliō is also found;[2] the grammarians Diomedes and Priscian say it was used by the oldest writers, and Diomedes quotes auxiliem from a speech of Gaius Gracchus.[3] Plautus and Terence use the old infinitive auxiliārier.[3][1]
Etymology
It is from Latin auxilium (“help, aid”) + -ō, a denominative verb.[2][1][3] De Vaan lists auxilium (from Plautus on) among the derivatives of augeō (“to increase”), which goes back to Proto-Italic *augeje/o- and Proto-Indo-European *h₂eug- (“to grow”).[4]
Earliest recorded meaning
Its first known use is in Plautus' Trinummus, where one character tells another that there is no better way to help a third.[3][2][5]
Semantic evolution
The TLL calls it a word of everyday speech, rarely used by poets and prose writers, though common in the medical writers.[3] Terence uses it twice,[3] and Cicero perhaps only once, in his letters.[6] Caesar uses it of bringing military help, as when Caesar's men had no opportunity to help,[2] and the participle auxiliātus has a passive sense, “helped”, in Lucilius and Vitruvius.[3]
Of things it means to be helpful,[2] and especially in medicine to be a remedy: Ovid speaks of a medicine that helps,[2] and Pliny the Elder uses it often of remedies.[3][2] Statius has peoples clashing bronze to bring help,[2] and Pliny the Elder mentions the din raised to help the moon in eclipse.[3] In the Vulgate it unusually takes a genitive.[3] Church Latin kept it in the sense “help, aid, support”.[7]
