Female wants listener to show concern (4)
I believe the answer is:
fear
'concern' is the definition.
(I know that concern can be written as fear)
'female wants listener' is the wordplay.
'female' becomes 'f' (abbreviation).
'wants' says to put letters next to each other.
'listener' becomes 'ear' (body part which hears or listens).
'f'+'ear'='FEAR'
'to show' is the link.
(Other definitions for fear that I've seen before include "Cutting edge" , "Anxiety caused by danger" , "Dread, alarm" , "Consternation" , "Feeling of dread" .)
