pastrami (n.) Look up pastrami at
1940, from Yiddish pastrame, from Rumanian pastrama, probably from Turkish pastrima, variant of basdirma "dried meat," from root *bas- "to press." Another possible origin of the Rumanian word [Barnhart] is Modern Greek pastono "I salt," from classical Greek pastos "sprinkled with salt, salted." Spelling in English with -mi probably from influence of salami.
