Fun with Words

My daughter-in-law and two little grandsons are in Folkestone  for half term so my granddaughter brought them to stay which was lovely.  How do you explain to a French 10 year old who speaks and reads excellent English the vagaries of "ough".  He was reading an English story and wanted to know how to pronounce "though".  We then went on to---bough, cough, rough, enough, bought, thought, sought, plough, sough, fought until I couldn't think of any more. What fun to find someone else who likes the sound of words!
