Definition

1. Noun:
   • A corn (on the foot): A clavus is a small, localized area of thickened, hardened skin that develops on the toes or feet, typically as a response to repeated friction or pressure from footwear.

Examples of Usage

• Noun:
  • Wearing tight shoes for years caused a painful clavus on her little toe.
  • The podiatrist treated the clavus by carefully paring it down and applying a protective pad.
  • A clavus is often confused with a wart, but it is caused by pressure, not a virus.

Advanced Usage

• Medical Terminology: In formal medical contexts, "clavus" is the precise Latin-derived term used by healthcare professionals (e.g., podiatrists, dermatologists) to describe a corn. The term distinguishes it from other skin conditions like calluses (which are broader) or verrucae (warts).
  • The diagnosis in the patient's chart was "clavus digiti quinti."

Variants and Related Words

• Corn (n): The common, everyday term for a clavus.

• Heloma (n): Another technical medical synonym for clavus.
• Callus (n): A broader, more diffuse area of thickened skin, often on the hands or soles of the feet, also caused by friction or pressure.

Synonyms

• Corn
• Heloma (medical)

Notes on Different Meanings

• The word "clavus" has a distinct, unrelated meaning in historical contexts, where it referred to a purple stripe on a Roman tunic denoting rank. However, in modern English, especially in medical and general use, it is almost exclusively used to mean a corn on the foot.
