dinosaur: [19] Dinosaur means literally ‘terrible lizard’ (something of a misnomer, since dinosaurs are not particularly closely related to modern lizards). The word was coined around 1840 from Greek deinós ‘terrible’ (which goes back to the same Indo-European base, *dwei-, as produced English dire [16]) and sauros ‘lizard’ (which occurs in its Latin form saurus in the names of specific dinosaurs, such as brontosaurus and tyrannosaurus).
