[Ultimately (partly via Persian lavaš and Turkish lavaş) from Armenian lavaš, variant of loš, from medieval Armenian lawš; perhaps from Armenian *law-, flat (compare modern Armenian dialectal lavaz, very thin) + -aš, noun suffix, or perhaps of Semitic origin and akin to Syriac layšā, lump of dough (from lāš, to knead; akin to Akkadian lâšu, Ge'ez losa, and Hebrew lāš, to knead).]
