early 15c., wadde, "small bunch of fibrous, soft material for padding or stuffing," of uncertain origin, perhaps from Medieval Latin wadda (14c., source also of French ouate, Italian ovate), or Dutch watten (source of German Watte), or Middle English wadmal (c. 1300) "coarse woolen cloth," which seems to be from Old Norse vaðmal "a woolen fabric of Scandinavia," probably from vað "cloth" + mal "measure."
The meaning "something bundled up tightly" (especially paper currency) is from 1778. To shoot (one's) wad "do all one can do" is recorded by 1860. The immediate source of the expression probably is the sense of "disk of cloth used to hold powder and shot in place in a gun." Wad in slang sense of "a load of semen" is attested from 1920s, and the expression now often is felt in this sense. As a suffix, -wad in 1980s joined -bag, -ball, -head in combinations meaning "disgusting or unpleasant person."
"to walk with short steps, swaying from side to side; to walk as a duck does," 1590s, frequentative of wade. Related: Waddled; waddling. The noun is recorded from 1690s.
Old English wadan "to go forward, proceed, move, stride, advance" (the modern sense perhaps represented in oferwaden "wade across"), from Proto-Germanic *wadanan (source also of Old Norse vaða, Danish vade, Old Frisian wada, Dutch waden, Old High German watan, German waten "to wade"), from PIE root *wadh- (2) "to go," found only in Germanic and Latin (source also of Latin vadere "to go," vadum "shoal, ford," vadare "to wade"). Italian guado, French gué "ford" are Germanic loan-words.
Specifically "walk into or through water" (or any substance which impedes the free motion of limbs) c. 1200. Originally a strong verb (past tense wod, past participle wad); weak since 16c. Figurative sense of "to go into" (action, battle, etc.) is recorded from late 14c. Related: Waded; wading.
Forbade to wade through slaughter to a throne,
And shut the gates of mercy on mankind,
[Gray, from "Elegy Written in a Country Churchyard"]
"waterproof high boots," 1841, plural agent noun from wade.
"watercourse," 1839, from Arabic wadi "seasonal watercourse," prop. participle of wada "it flowed." It forms the Guadal- in Spanish river names.
late 14c., "thin cake of paste, generally disk-shaped," from Anglo-French wafre, Old North French waufre "honeycomb, wafer" (Old French gaufre "wafer, waffle"), probably from Frankish *wafel or another Germanic source (compare Flemish wafer, altered from Middle Dutch wafel "honeycomb;" see waffle (n.)). Eucharistic bread first so called 1550s.
"kind of batter-cake, baked crisp in irons and served hot," 1744, from Dutch wafel "waffle," from Middle Dutch or Middle Low German wafel, from Proto-Germanic *wabila- "web, honeycomb" (source also of Old High German waba "honeycomb," German Wabe), related to Old High German weban, Old English wefan "to weave" (see weave (v.)). Sense of "honeycomb" is preserved in some combinations referring to a weave of cloth. Waffle iron is from 1794.
1690s, "to yelp, bark," frequentative of provincial waff "to yelp, to bark like a puppy" (1610); possibly of imitative origin. Figurative sense of "talk foolishly" (c. 1700) led to that of "vacillate, equivocate" (1803), originally a Scottish and northern English usage. Late 17c. Scottish also had waff "act of waving," variant of waft, which might have influenced the sense. Related: Waffled; waffler; waffling.
c. 1500, transitive, "to move gently" (through the air), probably from Middle Dutch or Middle Low German, ultimately from wachten "to guard" (perhaps via notion of a ship that guards another as it sails), related to waken "rouse from sleep," from Proto-Germanic *waht-, from PIE root *weg- "to be strong, be lively." Possibly influenced by northern dialect waff "cause to move to and fro" (1510s), a variant of wave. Intransitive sense from 1560s. Related: Wafted; wafting.
