"one of the external openings of the nose, a nasal orifice," late 14c., nostrille, from Old English nosþyrl, nosðirl, literally "the hole of the nose," from nosu "nose" (from PIE root *nas- "nose") + þyrel "hole" (from PIE root *tere- (2) "cross over, pass through, overcome"). For metathesis of -r- and vowel, see wright. After the second element became obsolete as an independent, its form was corrupted in the compound.
"beak or bill of a bird," Old English nebb "beak, nose; human face, countenance; beak-shaped thing," from Proto-Germanic nabja "beak, nose" (source also of Old Norse nef "beak, nose," Middle Dutch nebbe "beak," Old High German snabul, German Schnabel "beak," Old Frisian snavel "mouth"), which is of uncertain origin.
name given to various plants of the mustard family, including watercress, late Old English nasturtium, nasturcium, from Latin nasturtium "cress;" the popular etymology explanation of the name (Pliny) is that it is from Latin *nasitortium, literally "nose-twist," from nasus "nose" (from PIE root *nas- "nose") + past participle of torquere "to twist" (from PIE root *terkw- "to twist"); the plant so called for its somewhat acrid odor. Modern application to a South American trailing plant with orange flowers is recorded from 1704.
"viscid fluid secreted by the mucous membranes of animals," 1660s (replacing Middle English mucilage), from Latin mucus "slime, mold, mucus of the nose, snot," from PIE root *meug- "slippery, slimy," with derivatives referring to wet or slimy substances or conditions (source also of Latin emungere "to sneeze out, blow one's nose," mucere "be moldy or musty," Greek myssesthai "to blow the nose," myxa "mucus;" Sanskrit muncati "he releases"). Old English had horh, which may be imitative.
in anatomy, "nostrils," 1690s, from Latin nares, plural of naris "nostril," from PIE root *nas- "nose."
