Cunning female pockets credit card when standing up (7)
I believe the answer is:
evasive
'cunning' is the definition.
(thesaurus)
'female pockets credit card when standing up' is the wordplay.
I cannot really understand how this works, but
'female' could be 'eva' (I've seen this before) and 'eva' is found in the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for evasive that I've seen before include "Ambiguous" , "Prevaricating" , "Avoiding commitment" , "Shifty, dodging question" , "Devious" .)
