I've just completed the grid but not the end game, and I'm surprised that no-one has asked the questions I can't answer:
1. In 21 the third letter as required by the definition in the clue is an A, but the letter as required by the 3-word phrase would be U; the word if spelt with a U doesn't match the definition in the clue - which is correct?
2. In the same cell, 28 requires an L - surely LAU isn't one of the clashes, as it has nothing to do with the neat framework created by the other nine?
3. But having said that, the top row of that framework suggests the start of a helpful phrase, only to muddy things by throwing in a superfluous clash NG, where TH is required
4. And then, what does 'among others' mean? How are we supposed to know which of the un-clashing cells contain(s) additional letters needed for the phrase?
5. Finally, if a 'closed outline' is drawn through the omitted letters, it doesn't spell anything, just a sequence of 32 letters with a phrase hidden within them - is that what is needed?
The meaning of the title (sorry, me neither) is the least of my worries.
