Early 17th century: from Latin fatuus 'foolish' + -ous.

  • fade from Middle English:

    The early sense of fade was ‘grow weak, waste away’. The word comes from Old French fade ‘dull, insipid’, probably a blend of Latin fatuus ‘silly, insipid’ (source of E17th fatuous), and vapidus ‘vapid’ ( see vapour). The sense ‘lose freshness’ (faded colours) developed in English alongside the meaning ‘lose strength’.
