The word 火腿肠 is formed by sequentially combining the characters 火 (fire), 腿 (leg), and 肠 (intestine or sausage). 火腿 literally means "fire leg", referring to ham as a cured leg meat often prepared with heat or smoking. The addition of 肠 denotes a sausage form, resulting in a compound term that specifically indicates a ham sausage or frankfurter.
