2d: OK - I understand that 'preposterous' is here - "rarely" - a reversal indicator, not an anagrind; but no
reversal of my entry for 2d - with three confident letters and the fourth unch cycled through the alphabet, reveals to me any word of 4 letters clued by any rational combination of 'Prince', 'Hamlet', and 'somewhat'; and I can only find two real examples of the defined proper-name item that you specify with any different letter in the unch position other than the one I've used - and those work no better - the options give 'clearing the throat', 'Hindu festival' and blank, respectively...
In the first two cases, all the 4 letters are there - 'somewhat'- in one 6-letter word of the clue, so it's ambiguous to say the least.
And where does the Prince come in - is he part of the definition?
As I said, I'm pretty dense.
It doesn't affect the theme, but could get me disqualified for an incorrect entry - so if you can give me just a little more of a nudge it would be much appreciated.
