The phrase ‘I second that’ is commonly used in meetings or discussions to show agreement with a proposal or suggestion made by someone else. When someone says ‘I second that,’ they are formally supporting the idea or motion that has been put forward.
This expression originates from parliamentary procedure, where a motion needs to be seconded by another member before it can be discussed or voted on. By saying ‘I second that,’ the person is indicating that they agree with the proposal and want it to be considered further.
In everyday conversations, ‘I second that’ is often used more casually to express strong agreement with a statement or idea. For example, if someone suggests going out for pizza and another person says ‘I second that,’ it means they also think it’s a good idea and are in favor of it.
