Other forms: ballrooms
A ballroom is the large hall used for dances and formal functions. The hotel ballroom, a grand ballroom, book the ballroom.
It is the biggest room in a grand hotel or country house, and in practice it now hosts conferences and wedding receptions far more often than dances. Ballroom dancing is the whole discipline of partnered dances — waltz, foxtrot, quickstep, tango — done in a fixed hold, and it is the reason most English speakers know the word at all. Note ballroom-ready and the distinction from Latin dances, which are a separate competitive category.

“The ballroom holds four hundred at round tables.”
ballroom is a large room.
The ball in ballroom has nothing to do with the round object: it comes from French bal, a dance, from a Latin verb meaning to dance. Ballad and ballet are the same root, and all three began as things done to music with your feet.
From ball + room.
