(woops)............at last! I was trying to apply the 4-letter word to your definition! How foolish of me! Not an easy puzzle though, I think you'll agree. Thanks for the help --- I was getting desperate over the last one as usual!
I have a full grid and the 2 word epithet but am short of one of the T's required to make up the epithet (One T comes from 6a - where does the other one come from anyone please?)
