adj.“vexed, irritated,” c.1400, figurative adjectival use of past participle of nettle (v.). v.c.1400, “to beat with nettles,” from nettle (n.). Figurative sense of “irritate, provoke” is from 1560s. Related: Nettled; nettling. n.stinging plant, Old English netele, from Proto-Germanic *natilon (cf. Old Saxon netila, Middle Dutch netele, Dutch netel, German Nessel, M.Da. nædlæ “nettle”), diminutive of *naton, perhaps from PIE root *ned- “to twist, knot” (see net (n.)). “[N]ettles or plants of closely related genera such as hemp were used as a source of fiber” [Watkins].
