Word Origin & Etymology

Formed in English from the verb 'joke' (derived from Latin 'jocus', meaning a jest or pastime) and the agentive suffix '-er'. The playing card sense emerged in the United States during the 1860s for the game of euchre, likely evolving from 'Juker', a regional phonetic spelling of the game's name used for its highest-ranking trump card.
