Yes, thanks, I'm OK with that, in fact. It's the "(each) somehow related to each other" that's troubling me. Sure, I've got 5 pairs of anagrams, but no two pairs seem to have anything much in common.
Also, I'm stuck on the "Aussie fish". ?e?carp. "wex" = "swell", but not a type of carp, it would seem. Do I just need a better fish dictionary or have I gone wildly wrong somewhere?
