Enough in snug for whip-round? (4,2,5,1,3)

'enough' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'in snug for whip-round?' is the wordplay.
I cannot really see how this works, but
'in' is found in the answer.
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is present in the answer.
'whip' could be 'cat' (cat o' nine tails, cat for short is a type of whip) and 'cat' is found within the answer.
'round?' could be 'o' (round can mean a round object) and 'o' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?
