refraining

I'm a little stuck... Click here to teach me more about this clue!

'heavily maybe or holding back' is the definition.
I can't tell whether this definition defines the answer.

'judge coming down' is the wordplay.
'judge' becomes 'ref' (referee).
'coming down' becomes 'raining' (raining is a kind of coming down).
'ref'+'raining'='REFRAINING'

Can you help me to learn more?
