Man's back: time for little drink (5)
I believe the answer is:
snort
'little drink' is the definition.
'snort' can be an answer for 'drink' (I've seen this before). I am not sure about the 'little' bit.
'man's back time for' is the wordplay.
'man's' becomes 'ron's' (short for Ronald).
'back' is a reversal indicator.
'time for' becomes 't' (I've seen this in other clues).
'rons' in reverse letter order is 'snor'.
'snor'+'t'='SNORT'
Can you help me to learn more?
(Other definitions for snort that I've seen before include "Take illegal drug" , "Derisive noise made through nose" , "quick drink" , "Make derisive noise" , "Rough nasal sound of disgust or anger" .)
