Word History

Etymology

earlier, "dockyard for the construction and repair of naval vessels," borrowed from Middle French archenal, arsenail, arsenal (in reference to the naval dockyard of Venice), borrowed (with conformation of the final to -al -al entry 2) from Upper Italian (Venice) arzanà, presumably alteration (by metanalysis, with the initial taken as the preposition d', di "from") of darsenà (attested in Genoese, earlier in Medieval Latin as darsena, darsana), borrowed from Arabic dār al-ṣināʽa "place of manufacture," from dār "house" + al "the" (assimilated to aṣ) + ṣināʽa "manufacture" (derivative of ṣanaʽa "to make")

Note: Forms with final -ale (as arsenale, arzanale, arzenale) are attested in Italian in the sixteenth century and may be the immediate source of the English word. The French forms with -al may reflect these, though attested about a century earlier. As arzanà the Venetian word is attested in the text of Dante's Inferno ("nell'arzanà de' Viniziani," XXI, 7).
