What is the function of the 'warrant' in an argument?

The function of the 'warrant' in an argument is to establish the logical connection between the claim being made and the supporting evidence. Essentially, it explains why the evidence is relevant to the claim and how it supports the argument's validity. This is crucial because an argument is not just a statement of opinion; it requires a reasoning process that shows how the evidence backs up the claim.

By clarifying this connection, the warrant helps the audience understand the rationale for accepting the argument as credible. It serves as a bridge that allows the speaker to move from the evidence presented to the conclusion drawn, thus reinforcing the overall structure of the argument. The effectiveness of the argument often depends on the strength and clarity of the warrant, as a weak or unclear warrant can lead to confusion or a lack of persuasion from the audience.
