With respect, could it be that the "W" simply stands for "with," and the question could be stated as -' "the" with "r" goat,' the correct answer being an anagram of "ther," giving us "tehr."
ps, whilst doing the crossword myself, I came up with "tahr." Embarrasingly.
Thanks, celticminded. I had Tahr too, but more embarrassingly, I had spelled Yeats as Yates! Therefore, I couldn't get Hielans and I couldn't send in the crossword.
However, I have completed this week's so if I can help you in any way, let me know.
filibuster, there's only one thing worse than your incorrect spelling of "Yeats," and that's my incorrect spelling of "embarrassing" in my previous post!!
