Thank you alwayspuzzled. No, I've got no excuses, I have the 13th edition of Chambers which I probably bought after emigrating here from the UK in 1953 (before you were born!?)
I've never been a fan of Pabulum and this last effort of his confirms that opinion.
Anyway my grid is complete and I'll submit it (Send you the prize if I win!)
All the best
