The toponymy of the name "Legnano" is uncertain, as the early settlement was known by several names, but it is obvious that Legnano's name is older than that of the surrounding municipalities. "Legnano" could have originated as a predial adjective, formed from the name of the most prominent landowner in the area. In Legnano's case, this landowner's name could have been "Lemennius" or "Limenius", to which was adjoined the suffix -"anum". This land ownership was more extensive than the modern "comune" of Legnano having a surface corresponding to his modern urban area, the "Legnanese".
