Thanks sudokulover.
That was fast.
I think C(aught) and almost every time (meaning three out of 4) leave.
I can only parse it after the answer.
Struggling with this one.
Is 1A an anagram of the third and fourth words. I am not sure Obscure describes the meaning of the anagram.
I have do not yet have any down answers to verify that 1a is correct.
