waft (v.) Look up waft at Dictionary.com
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- (see wake (n.1)). Possibly influenced by northern dialect waff "cause to move to and fro" (1510s), a variant of wave. Intransitive sense from 1560s. Related: Wafted; wafting.
