Well done BBM2, and also to Jono as the runner-up. I appreciated your vote, Tyke, and the mentions from Aristo, Jono, Chrise, Paul, Spike, FJ and Ginge.
Cheers to the Prof for the challenge. I found the clip fascinating. 🌕
Ginge, thanks for your input re #7. I've seen the device used in Azed, but find it hard to execute. The sub. anag. is easier. I was originally going to put 'This', then that seemed redundant with a synonym as well. That's why I thought the resulting synonym was ghostish. 👻
Paul. I forgot to say that I had a smile at your dog clue in Clueless.
