Etymology: "Knapweeds" is simply the plural of "knapweed," a noun for thistle-like flowering plants in the daisy family, mostly of the genus Centaurea. The singular is an alteration of an older form, "knopweed," in which the "k" and "p" have been reshaped over time, most likely by speakers who found the earlier spelling and sound unfamiliar. The "knop" part of the older form referred to a knob or bud, a reference to the plants' rounded flower heads, while "weed" was the ordinary English word for a plant, so the name simply described a knobbed or budded plant.
