Thanks for playing everybody, that was the last Weekend Warm Up(in this format anyway), I'm messing about with the trial version of Crossword Compiler to see if I can use it(I'm a bit technophobic)and produce an occasional crossword instead.
Thnks, Joan and Bullfrog. I had no idea it was there; I assumed it was Latin, but there are so many Latin terms in the regular part that it didn't occur to me to look elsewhere.
