Social worker upset Anne, I sense (7)
I believe the answer is:
antenna
'i sense' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'social worker upset anne' is the wordplay.
'social worker' becomes 'ant' (ants are social insects).
'upset' is a reversal indicator.
'anne' backwards is 'enna'.
'ant'+'enna'='ANTENNA'
Can you help me to learn more?
(Other definitions for antenna that I've seen before include "Radio aerial" , "Insect's feeler" , "Feeling part" , "Transmitting aerial" , "sensitive feeler" .)
