Etymology: Bitterweed is about as transparent as English compounds get: it simply joins "bitter" and "weed," the second of which in Old English meant a plant in general, not specifically an unwanted one. The "weed" sense of an unwelcome plant only narrowed over time, which is why a word built from two plain Anglo-Saxon-rooted parts still reads as a description of a particular bitter-tasting plant rather than any bitter growth. The "bitter" half carries the older story. It descends from Old English "biter," tied to the verb "bite," so the underlying idea is something that bites the tongue with its taste. That physical sensation of sharpness is what gives the plant its name, and it explains why the word fits so naturally on the many wild species that gardeners and farmers have called by this name.
