From Scots weid. The longer form weidinonfa (Old Scots wedonynpha) is attested since the 1500s. Jamieson's Etymological Dictionary of the Scottish Language analyses the longer form as a compound meaning "onfa(ll) of a weed", whereas the Scottish National Dictionary/DSL considers the short form a derivative of the longer form, and derives its first element from Old English wēdan, from wōd.
