means A long, thin smoked sausage of beef or pork and beef, traditionally served in a sliced bun — the proper name for what most people just call a hot dog.

from Named for Frankfurt, Germany, where this style of sausage was being made and sold by at least the 1400s-1600s, long before it crossed the Atlantic. German immigrants brought the frankfurter to the US in the 1800s, where it got stuffed into a bun, renamed 'hot dog' (possibly from jokes about mystery-meat content, possibly from vendors' carts shaped like dachshunds — the dachshund-sausage link is well attested, though the exact coining of 'hot dog' is murkier than the legends claim), and marketed as thoroughly American. The 'frankfurter' name survived alongside it, a quieter reminder of the sausage's actual passport.
