grisly: [OE] Middle English had a verb grise ‘be terrified’, which points back via an unrecorded Old English *grīsan to a West Germanic *grīdenoting ‘fear, terror’, from which grisly would have been formed. Dutch has the parallel formation grijzelijk. In 1900, the Oxford English Dictionary described grisly as ‘now only arch and lit’, but since then its fortunes have recovered strongly, and it is now firmly part of the general language.
