I finally got the answer to C, but don't see what plai has to do with it. It isn't a word in my Chambers. Can anyone explain?
I too got two words finishing with X, though the S word was a new one on me. Some of you may be too young for the T word. Think stationery.
I've finished all bar one. Can anyone help with the N word. I have NA?O?A. I can see an island, but nothing else. I did manage to fill them all in the grid OK.
I've had immense difficulty parsing many of the clues and have had to accept two-thirds parsing. I usually have the definition. And I wouldn't have got this far without all your help, especially Chrise. So thank you.
