Derivations
Forms
vassus m (genitive vassī); second declension[1] Variant spellings include bassus, guassus, vassis and vasus.[2][3]
Etymology
It is borrowed from Gaulish *wassos (“young man, squire”),[1][4][3] from Proto-Celtic *uɸostos (“servant”).[1] Cognate with Old Irish foss (“servant”), Welsh gwas (“youth, servant”) and Breton goaz (“servant, vassal, man”).[1][4][3] Etymonline explains the Celtic word as “one who stands under”, from Proto-Indo-European *upo (“under”), and Köbler also compares that root.[4][3]
Earliest recorded meaning
It is first recorded in the Salic law (Pactus legis Salicae), which Köbler dates to about 507–511, in the sense “servant, serf”.[3][1]
Semantic evolution
Its senses rose with the status of the men it named: from an unfree serf to a servant of low rank who was not necessarily unfree, a servant provided with a beneficium, a free servant of higher rank, and finally a vassal in the technical sense, a lord's man who had received a fief from him.[2] The vassals of the king or emperor (vassus dominicus, regis) and those of counts, bishops and abbots often acted as public officials, and the word could even describe a person of high rank in political dependence.[2] The sense “feudal vassal” is attested by the 9th century.[1]
Köbler lists it in the capitularies, church councils, formularies, charters and the laws of the Alamans and Bavarians, and a gloss renders it in Old High German as kneht (“servant”).[3] From it was formed vassallus, the source of French and English vassal.[1][4]
