vagus
Etymology and origin of the Latin word vagus
Pronunciation
Forms
vagus (feminine vaga, neuter vagum, adverb vagē); first/second-declension adjective[1]
Etymology
The origin is uncertain.[1] De Vaan derives it from Proto-Italic *wago-, possibly inherited from Proto-Indo-European *Hwog-o-, comparing Germanic verbs for tottering or wavering, such as Old Norse vakka, Old High German wankōn (“to totter, stagger”) and Old English wincian (“to nod”), which could continue a nasal present *Hu-en-g-.[2][1] The OLD likewise compares Old Norse vakka (“to totter”) and Lithuanian vínguoti (“to make a detour”), and takes it to be related to vacillāre.[3] Lewis and Short connected it with vehere “to carry”, an older view.[4]
Earliest recorded meaning
It is attested from Naevius onwards.[2][5] Lucilius uses it of an exile who must “wander and live outside the law”.[3]
Semantic evolution
Its core sense was moving freely from place to place, said of exiles, nomads, flocks and birds,[3][4] and the planets were stellae vagae “wandering stars”.[3][6] From this it meant shifting or inconstant, of winds and the sea, and scattered, of troops spread over a wide area.[3] In Cicero and Seneca it described rambling speech and roundabout inquiry,[3] and it was used of rumours without a clear source and of fickle people and lovers.[3]
In Ecclesiastical Latin and canon law a vagus was a person without any fixed domicile,[7] and in medieval Latin the noun meant a wandering minstrel or scholar.[5] The figurative sense “indefinite” passed to French vague and English vague.[8]
