As usual, whatsoever wavelength I operate on it is not Picaroon's!
I had never heard of 14d although the parsing pointed me in the right direction & Google solved it for me.
It's a DNF as I have A_V_S for 23d my LOI so am pretty sure one of my crossers is wrong, or its a word that I don't know.
My familiarity with the subject made 5,1,15 leap out at me once I had a few crossers but I where the addictive additive comes into it I have no idea!
I know how revered Picaroon is in this community but once again a pretty joyless experience for me which I guess makes me the outlier.
Any help with 23d much appreciated.
