Hi LeenaH - it's always nice to include any special instructions attached to the puzzle, such as the following for this one -

Clues are normal but a single letter must be added to each solution, making another word or phrase (as enumerated). These should be fitted into the grid, jigsaw-wise. The inserted letters include the whole alphabet at least once, but with three A’s and two E’s, F’s, N’s and T’s. The clues are listed in alphabetical order of the inserted letters.

Realised too late that this one has a preamble,ta.
