- A curious specimen of Gloucestershire dialect came out in an assault case heard by the Gloucester court magistrates on Saturday. One of the witnesses, speaking of what a girl was doing at the time the assault took place, said she was ‘badding’ walnuts in a pigstye. The word is peculiarly provincial: to ‘bad’ walnuts is to strip away the husk. The walnut, too, is often called a ‘bannut,’ and hence the old Gloucestershire phrase, ‘Come an’ bad the bannuts.’
