A more thorough explanation:

Definition: To cancel or relax a limit on how long people can talk about a topic during a parliamentary meeting.

Example: During a meeting, there may be a rule that each person can only speak for five minutes. However, if someone wants to talk more about the topic, they can ask to extend the debate. This means that the time limit is cancelled or relaxed, and people can keep talking for as long as they need to.

Explanation: The example shows how extending the debate works in a parliamentary meeting. It allows people to talk for longer than the usual time limit, which can be helpful if they need more time to explain their ideas or if there are many different opinions on the topic.
