Relating to joints or the points where bones connect and move together in the body.
From Latin 'articulus' meaning 'joint' or 'small member,' derived from 'artus' meaning 'fitted together.' The word evolved through Old French and entered English in the 14th century to describe anything pertaining to joints.
Your knees, elbows, and fingers are all artic joints—and the word 'article' (a separate piece of writing) comes from the same root because medieval scholars thought of text as being divided into separate 'joints' or sections!
