blindfold: [16] The original term for covering someone’s eyes with a bandage was blindfell [OE], which survived until the 16th century. This meant literally ‘strike someone blind’, the second element being the fell of ‘felling trees’. It appears that its past form, blindfelled, came to be mistaken for a present form, and this, together with some perceived connection with fold (presumably the ‘folding’ of the bandage round somebody’s head), conspired to produce the new verb blindfold.
