Look dissatisfied with a milk supplier in outer Southall (5)
I believe the answer is:
scowl
'look' is the definition.
(I know that scowl is a type of facial expression)
'milk supplier in outer southall' is the wordplay.
'milk supplier' becomes 'cow' (I've seen this in another clue).
'in' means one lot of letters goes inside another.
'outer' means to remove the middle letters.
'southall' with its centre removed is 'sl'.
'cow' placed inside 'sl' is 'SCOWL'.
'dissatisfied with a' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for scowl that I've seen before include "Lower" , "Angry frown" , "dirty look" , "Frown with displeasure" , "Look angry" .)
