Quick

Quick (/kwɪk/) is a term often used in the medical field to refer to the sensitive part of the fingernails and toenails.

Etymology

The term "quick" originates from the Old English word "cwicu", meaning "alive" or "lively". This is likely due to the fact that the quick is a living part of the nail, as opposed to the dead keratin that makes up the majority of the nail.

Definition

The quick is the part of a nail that is rich in nerve endings and blood vessels. It is the pink area that can be seen through the nail, especially when the nail is short. The quick is sensitive and can cause pain if it is cut or damaged.
