Like this clue? Annoyed with answer given first (6)
I believe the answer is:
across
'like this clue?' is the definition.
The definition and answer are not the same part of speech.
'annoyed with answer given first' is the wordplay.
'annoyed' becomes 'cross' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'answer given first' becomes 'a' (I can't justify this - if you can you should give a lot more credence to this answer).
'cross' put after 'a' is 'ACROSS'.
Can you help me to learn more?
(Other definitions for across that I've seen before include "From one side to another" , "ax" , "what follows one here" , "As this is entered" , "sort of clue?" .)
