enshroud (v.)

Old English scrud "a garment, article of clothing, dress, something which envelops and conceals," from West Germanic *skruthan, from Proto-Germanic *skrud- "cut" (source also of 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.)).

The specific meaning "winding-sheet for a dead body, cloth or sheet for burial," to which the word now is restricted, is attested from 1560s. The 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.

word-forming element meaning "in; into," from French and Old French en-, from Latin in- "in, into" (from PIE root *en "in"). Typically assimilated before -p-, -b-, -m-, -l-, and -r-. Latin in- became en- in French, Spanish, Portuguese, but remained in- in Italian.

Also used with native and imported elements to form verbs from nouns and adjectives, with a sense "put in or on" (encircle), also "cause to be, make into" (endear), and used as an intensive (enclose). Spelling variants in French that were brought over into Middle English account for parallels such as ensure/insure, and most en- words in English had at one time or another a variant in in-, and vice versa.
