Avoid girl (4)
I believe the answer is:
miss
I believe this clue is a double definition.
'avoid' is the first definition.
(missing is a kind of avoiding)
'girl' is the second definition.
('miss' can be a synonym of 'girl')
(Other definitions for miss that I've seen before include "Fail to hit (the target)" , "Girl - bad shot" , "Pine for - young lady" , "Strike noisily; criticise" , "Fail to hit (something)" .)
