AThanks Drxx but we're never going to agree on this.
I've just looked again in Chambers dictionary and nowhere is bull mentioned under calf or calf under bull - yes I know there are bull-calfs but that is what the text says.
The saddest thing of all, to my view, is that the M?? is in the top right in contiguous, the L??? in the bottom right, the E???? in the bottom left and the C??? is in the top right in contiguous cells - so what that one of them has already been highlighted - what is worse, using the same cell twice or completely and needlessly changing one of the words in the text for a supposed synonym that appears nowhere in Chambers dictionary?
Anyway, I've made my point, the crossword is in the bin and I'm going to take my friend's dog for a walk in Wapping woods but the sun is shining:-)
