Origin & History of “treacle”

Treacle is etymologically an ‘antidote to the bite of wild animals’. The word comes via Old French triacle and Latin thēriaca from Greek thēriakḗ. this was short for antídotos thēriakḗ ‘antidote to poisonous animals’, thēriakḗ being a derivative of thēríon ‘wild animal, poisonous animal’, which in turn came from thḗr ‘wild savage’. It retained its original meaning into English, but it then gradually broadened out into ‘medicine’, and the practice of disguising the unpleasant taste of medicine with sugar syrup led in the 17th century to its application to ‘syrup’.
