sail: [OE] Sail has numerous relatives in the other Germanic languages, among them German and Swedish segel, Dutch zeil, and Danish sejl. These all come from a prehistoric Germanic *seglam, which some have traced back to an Indo-European *seklom. This was presumably formed from the same Indo-European base (*sek- ‘cut’) that produced English dissect, saw, segment, etc, and so sail may signify etymologically a piece of ‘cut’ cloth.

sail (n.)youdaoicibaDictYouDict
Old English segl "sail, veil, curtain," from Proto-Germanic *seglom (cognates: Old Saxon, Swedish segel, Old Norse segl, Old Frisian seil, Dutch zeil, Old High German segal, German Segel), of obscure origin with no known cognates outside Germanic (Irish seol, Welsh hwyl "sail" are Germanic loan-words). In some sources (Klein, OED) referred to PIE root *sek- "to cut," as if meaning "a cut piece of cloth." To take the wind out of (someone's) sails (1888) is to deprive (someone) of the means of progress, especially by sudden and unexpected action, "as by one vessel sailing between the wind and another vessel," ["The Encyclopaedic Dictionary," 1888].
