The Clueless 80 word is: SCHOOLTEACHER
Clues to be submitted by 16.30 BST tomorrow (3rd October) with the winner being announced soon after.
I was going to choose mathematics, but I think I chose that in Clueless 16 and I'm not going to scroll down that many pages to find out! (or is there a quicker way to find old pages?)
Good luck everyone!
