fright: [OE] Prehistoric Germanic *furkhtaz, an adjective of unknown origin (not related to English fear), meant ‘afraid’. From it was derived a noun *furkhtīn, which was the basis of one of the main words for ‘fear’ among the ancient Germanic languages (not superseded as the chief English term by fear until the 13th century). Its modern descendants include German furcht and English fright (in which the original sequence ‘vowel plus r’ was reversed by the process known as metathesis – something which also happened to Middle Low German vruchte, from which Swedish fruktan and Danish frygt ‘fear’ were borrowed).
