Feeler from worker girl rejected (7)
I believe the answer is:
antenna
'feeler' is the definition.
(I know that feeler can be written as antenna)
'worker girl rejected' is the wordplay.
'worker' becomes 'ant' (worker is a type of ant).
'girl' becomes 'anne' (girl's name).
'rejected' is a reversal indicator.
'anne' written backwards gives 'enna'.
'ant'+'enna'='ANTENNA'
'from' acts as a link.
(Other definitions for antenna that I've seen before include "Feeling part" , "Feature of dish" , "sensitive feeler" , "Aerial - insect feeler" , "receiver" .)
