Hi Malone,
If memory serves, you use an actual Chambers dictionary rather than the app - if I'm wrong please let me know.
This is relevant because, once you've identified what type of clue it is in regards to solving, the app allows you to go through all the options by removing and then replacing the potential extra letter. In these type of clues I always start by removing the final letter first, and then if that doesn't work, try the penultimate letter etc. until I see the answer. In this instance the falconry term appeared before the actual answer. Obviously, this solving techniques is not available if one is using the hardback edition rather than the app
