Hi Mary,
I was at the same place as you a while back.
Then I googled British "theme word" layout. Theme word is 8 letters.
When you see that, you will know what colours to use where
and what the 1, 2 or 3 letters in a cell represent.
It is not as "dicey" as it looks.
The words you take out of some clues before solving lead you to the 8-letter theme word. But there is no other use for them.
