Swarovski, pronounced Svar-Off-Ski (Svar-Off-Skee ?) has already been done here by Muskox and Fixfire.
Nonetheless, I figure some might smile at the way a friend of mine, (now deceased) used to pronounce Swarovski —>
“Sah-Vors-Kee” .
There is humor in that.
Anyway, my all time favorite mispronounced / misspelled firearm name is by far the distortion of the names of cartridges designed by and firearms built by the excellent and long standing WJ Jeffery Company.
I always chuckle when I see or hear, “Jefferies”, sometimes “Jeffries”, (as in caliber .404 “Jefferies”, .500 “Jeffries” etc.)
