A curling tournament or competition, particularly one organized as a social event, common in Scotland and Canada.
From Scottish, likely combining 'bon' (good) with 'spiel' (a turn or match), though some sources debate whether 'spiel' comes from Dutch or German influence.
The Scots exported curling and bonspiels to Canada so thoroughly that Canada now dominates the sport—it's a beautiful example of how cultural traditions travel with immigrants.
