Undy, or ondy(old fr. undé and oundé, mod. fr. ondé), frequently termed wavy: one of the lines of division(as its name implies) drawn like the waves of the sea. It is found in the earliest rolls of arms, being more frequently applied to the fesse or bar. though also to the bend, and occasionally even to the cross, chevron, &c. ‘Oundé de long’ probably means paly wavy. (See Bar and Paly.)
