Definition

Adjective: * Having an abnormally inward-curving or sagging spine, particularly in the lower back. This term is most commonly used to describe this condition in horses and other four-legged animals, but it can also apply to humans. The condition is formally known as lordosis or, specifically in horses, equine lordosis.

Usage and Examples

The adjective "swaybacked" is used to describe the physical condition of a subject. It typically precedes the noun it modifies or follows a linking verb like "is" or "was."

• Describing an animal:

  • The old, swaybacked mare still enjoyed gentle walks in the pasture.
  • Veterinarians examined the swaybacked donkey to ensure it was not in pain.
  • The rancher avoided breeding from the swaybacked cow.

• Describing a person or object (less common):

Advanced Usage and Nuances

• Technical/Medical Context: In formal contexts, "lordosis" is the preferred term, especially for humans. "Swaybacked" is considered more descriptive and colloquial.
• Connotation: The word often implies a permanent or long-term structural condition due to age, genetics, or strain, rather than a temporary posture. It can carry a neutral descriptive tone or, when describing animals, a slightly pitiful or worn-out connotation.
