(third-person singular simple present mithers, present participle mithering, simple past and past participle mithered)
Late 17th century, unknown origin, possibly Welsh moedrodd to worry or bother. Possible alternative from the Welsh meidda (“to beg for whey") or perhaps meiddio (“to dare or venture"). Bear in mind that the "dd" in Welsh corresponds in sound to the "th" in mither, and English also has moider and moither.
- (Scotland and Northern England) mother
Late variant of Old English mÅdor.
