Thank you Scorpojo, Rossim and Chrise
I did have eight still to get, but I have now finished, though I did get some further help from my friend in Sheffield (I'm in Exeter). At least 3 more answers I had nearly got but couldn't see why. It seems to me that Paul's clues are often doubly difficult as you have to get the synonym and then do something with it. These days I'm finding the synonyms difficult. I'd never have got 12d without the hint from Scorpiojo. So thank you all. I can get on with my chores now.
