Vet vs. Whet — What's the Difference?

Vet originally referred to the process of examining animals by a veterinarian but has expanded to mean any thorough examination or evaluation, such as vetting a candidate for a job. It implies a careful and detailed check to ensure suitability or credibility. Whet, on the other hand, derives from sharpening tools or blades and extends metaphorically to increasing one's desire, interest, or appetite for something. E.g., whetting your appetite with a starter.

While vetting often involves checking credentials, histories, or qualities to confirm authenticity or suitability, whetting is about honing or enhancing. For example, you vet a person's background before hiring, whereas you might whet your skills by practicing or taking new courses.

Vet can be used in both professional and casual contexts, signifying the act of making sure something or someone meets certain standards or criteria. Whet, however, is more specific in its use, typically relating to sharpening or stimulating an interest, appetite, or ability.

The outcomes of vetting are usually decisions based on suitability, such as approving a project or hiring a person. The outcome of whetting is an enhancement or intensification, such as a sharpened knife or increased anticipation.

Vetting requires access to information, resources for investigation, and a criterion for evaluation. Whetting, however, needs an object or subject to be honed and a method or action that leads to its intensification or improvement.
