From Middle English blyndefolde, blyndfuld, blynfold, blindfeld, blindfelt, yblynfeld, variants of y-blyndfalled, blyndfelled, etc. ("stricken blind, blindfolded"), past participle of Middle English blindfellen (“to strike blind”), from blind (“to blind”) and fellen (“to fell”), equivalent to blind + felled. Later influenced by the unrelated verb fold.
