verb/xusˈtaɾ/
to joust
From Vulgar Latin *iuxtāre, from Latin iuxtā (“near, beside”). Probably arrived through the intermediate of Old Occitan jostar (and later influenced by justo) or Catalan justar. As it was a term relating to chivalry and knighthood, it may have been treated or seen as foreign, or it may have been influenced by Gallo-Romance languages. Compare Catalan justar, French jouter, Italian giostrare. Cf. also ayustar.
