A world championship(s) is the top achievement for any sport or contest. The title is usually awarded by contests, ranking systems, stature, ability, etc. This determines the best nation, team, individual (or other entity) in the world in a particular field. Certain sports do not have a world championship, instead they may organise a World cup competition, or they may organize both. Often, the use of the term cup or championship in this sense is just a choice of words. Some sports have multiple champions because of multiple organizations such as mixed martial arts, boxing and wrestling.
Certain sports do not have a world championships or a world cup as such, but may have one or several world champions. Professional boxing, for example, has several world champions at different weights, but each one of them is decided by a "title fight", not a tournament.
Famous quotes containing the word world:
“When I develop my recipes I always look for ways to create what I call the Big Taste. While I enjoy eating simple grilled foods, what interests me when I cook are dishes with a taste that is fully dimensional.”
—Paula Wolfert, U.S. cookbook writer. Paula Wolferts World of Food, Introduction, Harper and Row (1988)
