supercilious: [16] The etymological notion underlying supercilious is of raising the ‘eyebrows’ as a sign of haughty disdain. It comes from Latin superciliōsus, a derivative of supercilium ‘eyebrow’, hence ‘haughtiness’. This was a compound noun formed from the prefix super- ‘above’ and cilium ‘eyelid’ (source of the English biological term cilium ‘hair-like process’ [18], whose meaning evolved via an intermediate ‘eyelash’).
