well it seems to me that 12 reads: words 1 and 2 reversed (giving definition), words 3,4 and 5 as written (giving the first 5 letters), opposite of word 6 + conventional letter for word 7 (giving letter 6). Have I got this completely wrong then?
ah, thank you muraria (and the rest of you) - I see I'd been cherry-picking the reversals rather than going all through them - just as well I'm not blogging this month!
If it hasn't been explained already ... 15 ACROSS one of themed words. Assume it is British not US spelling. Could someone please explain the construction / word play. I have the revolutionary on the end and O for Oscar
