'banqueteer' originates from English formation combining 'banquet' and the agentive suffix '-eer' (from French '-ier'), where 'banquet' meant 'feast' and '-eer' meant 'person associated with or engaged in'.

'banqueteer' developed from Middle English and Old French sources: Old French 'banquet' (a small bench or a feast) led to Middle English forms such as 'banquet' and agentive forms like 'banquetier', which eventually became the modern English 'banqueteer'.

Initially it referred mainly to a person attending or involved in a banquet ('one associated with a feast'), but over time it also came to be used as a verb meaning 'to give or host a banquet' and as a noun meaning 'the act of hosting a banquet'.
