A feeler from an insect Anne brought back (7)
I believe the answer is:
antenna
'a feeler' is the definition.
(I know that feeler can be written as antenna)
'an insect anne brought back' is the wordplay.
'an insect' becomes 'ant' (ant is a kind of insect).
'brought back' shows that the letters should be reversed in order.
'anne' in reverse letter order is 'enna'.
'ant'+'enna'='ANTENNA'
'from' is the link.
(Other definitions for antenna that I've seen before include "Transmitting aerial" , "sensitive feeler" , "Feeling part" , "Aerial - insect feeler" , "one feels" .)
