Pronunciation
Forms
iuvō (present infinitive iuvāre, perfect active iūvī, supine iūtum); first conjugation[1] An inscription has iouent, and Accius has a present iuvere.[2][3]
Etymology
It is inherited from Proto-Italic *ijow-, inherited from Proto-Indo-European *h₁i-h₁euH- (“to help”), a reduplicated present.[2][1] The perfect and participle point to an earlier stem *iuwa-, and the present may be an iterative or a back-formation from adiuvō.[2] Cognate with Sanskrit अवति (ávati, “helps, protects”) and Old Irish con·oí (“protects”).[2][4]
Earliest recorded meaning
It is found in the Carmen Arvale and in Plautus, as a prayer to Jupiter to help.[2][3] Köbler dates Plautus c. 250–184 BC.[5]
Semantic evolution
In Classical Latin it was to help or assist a person, to promote a cause or back an opinion, and of things to benefit or be of use, as in quid iuvat? “what use is it?”.[3][6] It was to improve things, as harrowing improves a field, and to delight or please.[3]
Its compound adiuvāre gave Late Latin adiūta, Old French aide and English aid.[7] It survives as Italian giovare.[1]
