A Ten Dollar Word

It's one of those words that is so long and looks impossible to pronounce. If it wasn't for my hubby's occupation in the medical field I wouldn't have even known what a sphygmomanometer was, much less anything about sphygmomanometer price and availablility. We were talking about blood pressure and blood pressure machines and he mentioned the sphygomomanometer the doctor's office uses vs the personal bp cuff he has at home. It's one of those words that make you blink and look off into the distance for a moment while you try to place it, then realize you can't without an explaination.
