'banqueter' originates from French, specifically the word 'banquet' plus the agentive suffix '-er' meaning 'one who takes part in or provides a banquet'.

'banqueter' developed via Middle English (from Old French 'banquet' meaning a feast) with an agent-forming element (Middle English forms such as 'banquetour' or similar) and eventually became the modern English 'banqueter'.

Initially related to the notion of a 'bench' or 'table' at which food was served (through 'banquet'), it came to mean 'one who attends or takes part in a feast' and now denotes people participating in a banquet.
