come-on

The term 'come-on' originates from the verbal imperative phrase 'come on', used since Middle English to urge someone to advance, hurry, or proceed. By the late 19th century, this phrase began to be nominalized, solidifying into the hyphenated form 'come-on'. The semantic evolution saw a shift from a general encouragement to a more specific sense of an enticement or lure, often with connotations of flirtation or deceptive persuasion. This reflects how a directive command transformed into a label for the act or object of solicitation itself, capturing the 'invitation to proceed' inherent in its original verbal meaning.

This is a phrasal noun derived from the verb phrase 'come on'. As a fixed compound, it is not productively segmented into smaller, independent morphemes in its nominal form. The components are the verb 'come' (from Old English cuman, meaning to move toward) and the particle 'on' (from Old English on, indicating continuation or progression).
