Mary is asking for very heavy hints.
1a is Colonel and 1d is Colonies.
The first 5 letters can be represented by a symbol. There are 14 symbols which can be called by the 11 letters in the circled cells.
Think question mark.
I think for 3d perfectly is the definition. A followed by 5 letter symbol (same as in 9A) may give the answer.
10a I believe is POI truncated and then a computer chip brand name.
I do not have 16d, though is seems like Charas like word.
I can do with hints on 30a, 8d, 17a and 22a.
Thanks.
