shroud: [OE] Shroud originally meant simply ‘garment’ – a sense which survived into the early modern English period (‘My princely robes are laid aside, whose glittering pomp Diana’s shrouds supplies’, Christopher Marlowe and Thomas Nashe, Dido Queen of Carthage 1594). Not until the late 16th century did the modern meaning ‘winding-sheet’ begin to emerge. The word derives ultimately from the prehistoric West Germanic base *skraud-, *skreud-, *skrud- ‘cut’ (source also of English shred).

shroud (n.)youdaoicibaDictYouDict
Old English scrud "a garment, clothing, dress," from West Germanic *skruthan, from Proto-Germanic *skrud- "cut" (cognates: Old Norse skruð "shrouds of a ship, tackle, gear; furniture of a church," Danish, Swedish skrud "dress, attire"), from PIE *skreu- "to cut" (see shred (n.)).

Specific meaning "winding-sheet, cloth or sheet for burial," to which the word now is restricted, first attested 1560s. Sense of "strong rope supporting the mast of a ship" (mid-15c.) is from the notion of "clothing" a spar or mast; one without rigging was said to be naked.
