Etymology

Origin of tendinitis

1895–1900; < New Latin tendin- ( see tendinous) + -itis

Explanation

Tennis players who overexert themselves might experience pain and swelling in their elbows, a sign they could be dealing with tendinitis — inflammation of the connective fiber within their joints. Tendinitis is a condition where a tendon, the thick cord that connects muscle to bone, becomes inflamed due to overuse or injury. The word tendinitis comes from the Latin word tendo, meaning "stretch," and the suffix -itis, which indicates inflammation. This condition is common among athletes and people who perform repetitive motions, causing pain and swelling in the affected joint.
