What does birthmark mean?
A birthmark is a mark, spot, or area of discolouration on the skin that is present at birth or appears shortly afterwards. Birthmarks arise from an overgrowth of pigment-producing cells (as in moles, café-au-lait spots, and Mongolian blue spots) or of blood vessels (as in port-wine stains and strawberry marks). Most are harmless and many fade over time, though some types warrant medical monitoring. The word carries a broadly neutral connotation: it may be mentioned matter-of-factly in describing someone's appearance, invoked poetically as a sign of identity or destiny, or discussed clinically by dermatologists. Because it functions as a convenient umbrella term, English speakers use it freely without needing to know the underlying medical cause. Related figurative senses are rare; the word remains overwhelmingly literal in modern usage.

Etymology of birthmark
Birthmark is a straightforward English compound of 'birth' (from Old English 'gebyrd') and 'mark' (from Old English 'mearc'). The compound arose natively in English, attested from around the early seventeenth century. It shares its elements with other native compounds such as birthright, birthday, and birthplace, rather than deriving from a classical root.
How birthmark is actually used
