Whip sends Albert back, telling him to keep quiet (4)
I believe the answer is:
lash
'whip' is the definition.
(I know that whip can be written as lash)
'back telling him to keep quiet' is the wordplay.
'back' says the letters should be written in reverse.
'telling him' becomes 'al' (I am not sure about the 'telling' bit.).
'to keep quiet' becomes 'sh' (as in shushing someone).
'al' in reverse letter order is 'la'.
'la'+'sh'='LASH'
'sends albert' 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 lash that I've seen before include "Bind tightly with a rope or cord" , "Birch" , "Stroke of the whip" , "Secure with rope" , "Whip; securely fasten" .)
