Word origin
From earlier hubbe, which has the same immediate origin as hob. Hub was originally a dialectal word; its ultimate origin is unknown. Compare German Hubbel (“bump on a surface”), from Proto-West Germanic *hubil (“bump, hill”) (which contains a diminutive suffix *-il); compare English hive, or perhaps ultimately from the same root as hip or hop.
