Etymology

It is inherited from Proto-Italic *augeje/o-, inherited from Proto-Indo-European *h₂eug-eie- (“to make grow”), from the root *h₂ewg- (“to grow”).[2][1] An s-stem noun of the same root, kept in Indo-Iranian, survives in augur, from *augos “reinforcement”, and augustus is derived from the same noun.[2]

Cognate with Venetic augar (“offering”),[2] Sanskrit उक्षति (ukṣáti, “grows”), Ancient Greek αὐξάνω (auxánō, “to increase”), Gothic 𐌰𐌿𐌺𐌰𐌽 (aukan, “to increase”) and Lithuanian áugti (“to grow”).[2][3][1]

Earliest recorded meaning

De Vaan dates it from Plautus onwards.[2] Pacuvius says the sky “quickens, shapes, feeds, makes grow and creates” all things.[3][4]

Semantic evolution

It meant to increase in size or number, to make living things grow, and to strengthen a state or a person's power.[3] It was used for promoting someone in rank and for glorifying, as Cicero says a man “increased the name of the Roman people”.[3]

It also meant to heighten feelings, as Terence's “increase my suspicion”, to make an illness worse, and to develop a talent.[3] In rhetoric it meant to make much of something, and Quintilian uses it for heightening the style.[3] Medieval music theory used it for widening an interval and lengthening a note.[5] English augment comes from Late Latin augmentare, and author from its derivative auctor.[6]
