The word is well-known too in Yorkshire. It is in the latter - and quite possibly second greatest of all England's counties - where we hear the verb 'to mither' in everyday usage. This word has a Welsh root but, I am told, is rarely use in its birthplace.
'Mithering' is what people do who like to fuss nonstop over matters which do not matter all that much.Hmm. I wonder why these two words sprang into my mind when I hear David Beckham's inane ramblings and complaints about not having been granted a knighthood.
Ah well Dave, perhaps oodles of money cannot buy you every desire of your heart, huh?
