To abdicate means to give up a position of power or responsibility, especially a throne. When a king or queen abdicates, they formally step down from ruling their country, usually passing the crown to the next person in line.

A famous example happened in 1936, when Britain's King Edward VIII abdicated so he could marry an American woman named Wallis Simpson. The rules at the time said he couldn't be king and marry her, so he chose to give up the throne. His younger brother became King George VI (the father of Queen Elizabeth II).

Leaders don't have to be royalty to abdicate. A president of a club might abdicate their position if they feel unable to fulfill their duties. A team captain might abdicate leadership when they realize someone else could do a better job.

People sometimes use “abdicate” critically, like saying someone abdicated their responsibility when they should have stayed and finished an important job. This suggests they gave up when others were counting on them. When a king abdicates thoughtfully after years of service, that's one thing. When someone abdicates responsibility by simply walking away from a mess they created, that's quite another.
