Be wary of female attention (4)
I believe the answer is:
fear
'be wary of' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'female attention' is the wordplay.
'female' becomes 'f' (common abbreviation).
'attention' becomes 'ear' (having someone's ear is having their attention).
'f'+'ear'='FEAR'
Can you help me to learn more?
(Other definitions for fear that I've seen before include "Dread, great anxiety" , "Dread, alarm" , "Terror" , "Qualms" , "Alarm, reverence" .)
