horrible: [14] The Latin verb horrēre was used for hair standing on end or bristling. A common cause of this phenomenon is of course fear, and so in due course horrēre came to mean ‘tremble, shake, be filled with fear and revulsion’. The latter sense has been carried through into English in the derivatives horrible, horrid [16], and horror [14]. (Horrid, incidentally, from Latin horridus, was originally used in English in the etymological sense ‘shaggy, hairy, bristling’ – ‘a rugged attire, hirsute head, horrid beard’, Robert Burton, Anatomy of Melancholy 1621 – but this did not survive beyond the early 19th century.) The Old French descendant of horridus was ord ‘filthy’, from a derivative of which English gets ordure [14].
