What does the term "subungual" refer to?

The term "subungual" is derived from Latin, where "sub" means "under" and "ungual" relates to nails (from "unguis," meaning nail). Therefore, "subungual" specifically refers to anything that is located beneath the nail. This anatomical term is commonly used in medical contexts, particularly in dermatology and podiatry, when discussing conditions or treatments that involve the area under the nail plate. Understanding this terminology is crucial for accurate documentation and communication in medical settings, particularly concerning nail disorders or injuries.
