basque.

Inherited from Old French baste, probably borrowed from Provençal or Occitan basto, from Frankish *bastijan (“to weave, plait, sew”). But others suggest it was named after the fashion of the Basques, the same as basquine and Spanish basquiña.

This form is inherited from Middle French and took precedence in the mid 15th century. Derived from Latin Vascō, singular form of the plural noun Vascones (see there for more). The transition of the initial -v- to -b- indicates a likely loan from Spanish or Occitan. Old French forms included bascle, and Old Provençal (Occitan), bascon, basclon. Medieval Latin had the plurals bascli, basculi, and basclos, basculos, but also basclones, basculones, while Renaissance Latin used Basculus among other names. The latinate forms with a v have remained in use too. Doublet of gascon and Vascon, from the accusative form Vasconem. A connection to the family of Basque euskal, euskara is uncertain.
