Loge - in reply to your #109 -
I fully understand that one particular verbal thematic sequence associated with (c) is closely related to the three 'normal' answers; what I was afraid of was that in some devilishly twisty way the denial of the moor involvement might somehow imply that the symbolic sequence to be entered (sustituted) might not be that of (c), but actually that of the much more familiar symbolic sequence normally associated with that verbal sequence.
But i think that's unduly paranoid, and I now think that it is the commencement of the symbolic sequence of ('c') itself that is to be entered.
But where? Substituted for what?
My point about the six non-symbolic clashing letters in 18,12 (I mistakenly said four earlier - so no anagram) is that they spoil the three 'normal' thematic sequences - Williamseal's clever pups will make a sadly incomplete rendering of these three thematic answers if they follow what is in my grid; and the symbolic sequences are incomplete anyway - in my grid they just peter out in mid flow...
So how are these six clashes to be resolved? - Loge's reply implies that nothing needs to be done.
Maybe the substitution of ????????? by (c) sorts it all out - but the statement in Lionheart's preamble that this substitution results in even more non-word entries is dispiriting - in sad contrast to the quite brilliant avoidance of any such thing in last week's Listener 4690.
Feeling very stupid - hoping for Pennies from Heaven...
