Etymology
Etymology Information

'Mob' originates from the Latin phrase 'mobile vulgus' (Neo-Latin), where 'mobile' meant 'movable, fickle' and 'vulgus' meant 'common people'.

Historical Evolution

'Mob' was shortened in English from the Neo-Latin phrase 'mobile (vulgus)' used in the 17th century; by the early 18th century the clipped form 'mob' was established in modern English.

Meaning Changes

Initially it referred to the 'movable' or 'fickle common people' and over time shifted to mean a disorderly crowd and, in certain contexts, an organized criminal group ('the Mob').
