eaves: eaves: [OE] The etymological meaning of eaves appears to be ‘going over the edge, projecting’. It comes from a prehistoric Germanic *obaswa, which was probably formed on *ob-, the base from which English over ultimately derives. The eavesdrip or eavesdrop is, or was, the area of ground on which rainwater thrown off by the eaves falls, so that somebody who stood within this area, with his or her ear to the door or window trying to listen in on private conversations, became known as an eavesdropper [15].

hazy (adj.): 1620s, hawsey, nautical, of unknown origin. Some connect it with German hase "hare," an animal which plays an important part in Germanic folklore, with many supernatural and unlucky aspects in medieval times (among the superstitions: a dead hare should not be brought aboard a fishing ship, and the word hare should not be spoken at sea). Another suggestion is Old English hasu, haswe "gray." Related: Hazily; haziness.
sough (v.): "to make a moaning or murmuring sound," Old English swogan "to sound, roar, howl, rustle, whistle," from Proto-Germanic *swoganan (cognates: Old Saxon swogan "to rustle," Gothic gaswogjan "to sigh"), from PIE imitative root *(s)wagh- (cognates: Greek echo, Latin vagire "to cry, roar, sound").

swoon (v.): c. 1200, "to become unconscious," probably from a lost Old English verb *swogan (as in Old English aswogan "to choke"), of uncertain origin. Compare Low German swogen "to sigh." Related: Swooned; swooning.
