gangster

The word 'gangster' is a modern American English formation from the late 19th century. It is built upon the older word 'gang', which traces back to Old English 'gang', meaning a journey or a set of things going together, from a Proto-Germanic root related to 'going'. The suffix '-ster', of Old English origin, originally denoted a female agent (as in 'spinster') but evolved into a general agent suffix, often with a derogatory or familiar tone. Thus, a 'gangster' is literally "one who belongs to a gang," with the term's specific association with organized violent crime solidifying during the Prohibition era in the United States.

In this word, it functions as the base meaning a group, especially one acting together. - ster: From Old English '-estre', a feminine agent suffix, later generalized. In this word, it functions as an agent suffix denoting a person associated with or characterized by the base word.
