Origin: 1935–40; < Yiddish pastrame < Romanian pastramă pressed, cured meat; a Balkanism of uncertain origin (compare Modern Greek pastramâs,Serbo-Croatian pȁstrma), perhaps ultimately < Turkish pastιrma, taken as variant of bastιrma, equivalent to bastιr-, causative stem of bas- press, squeeze + -ma verbal noun suffix
1940, from Yiddish pastrame, from Rumanian pastrama, probably from Turk. pastrima, variant of basdirma "dried meat," from root *bas- "to press." The other possible origin of the Rumanian word is Mod.Gk. pastono "I salt," from classical Gk. pastos "sprinkled with salt, salted." Spelling in Eng. with -mi
