waft (v.)Related entries & more
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.
waffle (v.)Related entries & more
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.
