Hi Ros, don't give up. It's probably because you don't regularly do "thematic" puzzles this concept seems strange. If you consider all the clues where the letter count is different from the allocated grid space and highlight these clues it should help. Each will have a square that has 1 standard letter in 1 direction and the thematic symbol in the crossing direction. If you split these squares diagonally with 1 of each in each half this should hopefully help.
