Is it so tip-top to be a boozer? (3)
I believe the answer is:
sot
'a boozer?' is the definition.
(both can mean someone who drinks a lot)
'is it so tip-top' is the wordplay.
I cannot really understand how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is located in the answer.
'so' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'to be' is the link.
Can you help me to learn more?
(Other definitions for sot that I've seen before include "drunk" , "One's often intoxicated" , "A chronic drinker" , "Habitual drinker" , "Lush" .)
