Other forms: wieners
You might call your favorite backyard cookout food a hot dog, but it's also known as a frankfurter or a wiener.
You're probably not thinking of Strauss waltzes and cream-topped tortes as you spread the mustard and relish on your hot dog, but in German, wiener simply means Viennese. Thank the lowly wienerwurst — "Vienna sausage" — parent of the sausage that we designate by this word today. The spelling weiner is also widely found in English, somewhat obscuring the word's origins.
