[Sans-Culotte]

I grew up hearing it as "rurnt." So, one syllable. I do enunciate it with two syllables for the unlearned from elsewhere.

My dad says it that way. He also pronounces the car make "Buick" as "Byurk" (one syllable).

Haven’t heard “Buick” pronounced in that way. What geographic region does your dad call home?
