Final answer:
An ad hominem fallacy is a logical fallacy directed at a person rather than the argument they give.
Step-by-step explanation:
An ad hominem fallacy is the logical fallacy that is directed at a person rather than the argument the person gives. It is an attempt to discredit the person making the argument rather than addressing the argument itself. This fallacy occurs when someone verbally attacks the person making the argument by mocking their appearance, intelligence, or character, or by highlighting something about their circumstances or insinuating that they are a hypocrite.
