Forms

Etymology

It is from Latin alacer (“brisk, eager”) + -ter, an adverb.[2][1] De Vaan considers deriving ⟨alacer⟩ from the root Proto-Indo-European *h₂elh₂- (“to wander”) of ambulō, though the semantics do not compel it and the suffix would be rare.[3]

Earliest recorded meaning

Gaffiot cites Frontinus, Apuleius and Justin, who has alacrius, and Köbler's earliest source is Ammianus.[4][5] Köbler dates Apuleius c. 125–175 AD.[5]

Semantic evolution

It meant eagerly, briskly, with ardour.[2][4]

British Medieval Latin used it for briskly, eagerly, as in Bede.[6]
