What does arthritic mean?
Arthritic functions primarily as an adjective describing anything affected by or characteristic of arthritis, the condition marked by inflamed, stiff, and painful joints. It most commonly appears before nouns such as hands, knees, or joints, as in 'her arthritic knuckles swelled in winter.' Less often it serves as a noun meaning a person who suffers from arthritis, though modern medical style tends to prefer person-first phrasing like 'a patient with arthritis.' The word derives from Greek arthron, meaning joint, the same root seen in arthritis, arthropod, and arthroscopy. Beyond literal medical use, arthritic can describe things figuratively — an old machine, a stiff hinge, or a slow bureaucracy — lending writing a vivid image of creaky immobility. Its tone is neutral to clinical in formal contexts and gently descriptive in everyday speech, making it a useful, precise term for discussing aging, injury, and bodily wear.
Suffering from or relating to arthritis; characterized by the joint inflammation and stiffness associated with arthritis.
"The old pianist's arthritic hands could no longer reach the octaves."
Frequently used attributively before body-part nouns.

Some consider this usage dated; person-first language ('people with arthritis') is often preferred in contemporary medical contexts.
Used only when arthritic functions as a noun referring to multiple people with arthritis.
"The clinic offers specialized therapy programs for arthritics."
The word 'arthritic' literally means 'of the joints' — the Greek 'arthron' behind it is the same root hiding in 'arthropod', the jointed-legged phylum that includes insects and crabs.

Etymology of arthritic
Arthritic traces back through Latin to the Greek word arthron, meaning 'joint,' combined with the adjectival suffix -itis-derived forms used for inflammatory conditions. English borrowed the term in the early modern period alongside its parent noun arthritis, which itself entered English via New Latin from Greek roots. Cognates sharing the same Greek root include arthropod (jointed-foot creatures), arthroscopy (joint examination surgery), and arthralgia (joint pain), all reflecting medicine's enduring reliance on Greek anatomical vocabulary.
