@timur,
Once thank you timur for your help. l looked into several sites but could not come up with an answeOncer starting with a K, l am sure that the compilers of this crossword will accept either spelling. l thought l knew the dupes one but could not think of name, l do have it in my word book but that is under a lot of stuff that is being moved around in my dining room, living in a builders yard at the moment,hubby DIYing. Once again THANK YOU.
