The banqueter enjoyed the delicious dishes served at the gala dinner.
Banqueter is derived from the Old French word 'banquet' (meaning a feast or banquet) and the suffix '-er' (meaning a person who). Thus, a banqueter is a person who participates in a feast or banquet.
Think of a 'banquet' as a grand feast, and remember that a 'banqueter' is simply someone who enjoys or takes part in that feast.
