What does whitlow mean?
Whitlow is a noun for a painful abscess in the tissue at the end of a finger or toe, usually beside or beneath a nail. Such infections commonly develop when bacteria enter through a cut, hangnail, or splinter and can produce swelling, throbbing, tenderness, and sometimes visible pus. The term is understood in British and American English, but it is less common in modern clinical writing than paronychia, the general term for infection around a nail, or felon, often used for a deep abscess of the fingertip. Whitlow therefore remains especially familiar in descriptions of everyday minor injuries and in older medical language. It is worth knowing because the word identifies a very specific, often intensely painful problem rather than any general sore or swelling of the hand. In a patient, however, the distinction can be clinically important: a superficial nail-fold infection and a deep fingertip abscess may require different forms of assessment and treatment.

Etymology of whitlow
The word is recorded in Middle English as whitlawe and is conventionally analyzed as whit-, an older form of white, combined with lawe, an old spelling of law. The second element's role in the original compound is not fully transparent, even though the modern word clearly denotes a swelling or abscess. Whitlow developed within English and does not have a widely recognized close cognate in another language.

How whitlow is actually used
Most often used for an abscess of the fingertip itself. The clinical term paronychia more broadly denotes infection of the skin or tissue around a nail; the terms are sometimes used loosely, but they are not perfectly interchangeable.
