ragweedn.

Brit.

/ˈraɡwiːd/, U.S.

/ˈræɡˌwid/

Forms: late Middle English ragwed, 1600s– ragweed.

Origin: Formed within English, by compounding. Etymons: rag n.², weed n.¹

Etymology: < rag n.² + weed n.¹ In sense 2 so called on account of the ragged form of the leaves. The reason for use in sense 1 is unclear, as ‘ragged’ does not well describe the plant butcher's broom. T. Hunt ( Plant Names Medieval Eng. (1989) 56) has suggested that the gloss is erroneous. Compare earlier ragwort n.¹

†1. Apparently: butcher's broom, Ruscus aculeatus. Obsolete. rare.
