Beat making assistance (4)

I believe the answer is:

abet

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

'assistance' is the definition.
The definition and answer are not the same part of speech.

'beat making' is the wordplay.
'making' indicates an anagram.
'beat' is an anagram of 'ABET'.

Can you help me to learn more?

(Other definitions for abet that I've seen before include "Aid (in wrongdoing)" , "helpful" , "Encourage (wrongdoing)" , "Support, aid" , "Aid as in committing crime" .)

I've seen this clue in The Mirror.
