I only send in the mail on sunday prizeword. The weekday ones i just do for
relaxation. I only ever use 2nd class, because I dont believe it gets ther any faster if you put on 1st class. It's a rip -off!
those two way spelling were always something i tripped over as well, and still do sometimes. nowadays, I look at he bit that appears to means 'sounds like' and the part of the clue it is attached to is usually the wrong spelling.
So in this clue, some say is the 'sounds like' and is by 'eagles nest' which would be eyrie, so the other spelling should be the one that is being looked for. Does that make sense?
