The action of bending or being turned aside; in British English, an alternative spelling of deflection.
From Latin 'deflexio' or derived from 'deflex'. Both 'deflexion' and 'deflection' derive from the same Latin root, with 'deflexion' being the British variant that's less commonly used today.
In old medical texts, you'll find 'deflexion' describing the bending of body parts—it's the technical term for what happens when your knee bends or your spine curves. The word has largely been replaced by 'deflection' in modern English, but it's still found in some British and Australian texts.
