'help' is the definition.
(synonyms)

'getting an excellent figure' is the wordplay.
'getting' is an insertion indicator.
'an' becomes 'i' (Roman numeral for one).
'excellent figure' becomes 'ad' (I can't explain this - if you can you should give a lot more credence to this answer).
'i' placed within 'ad' is 'AID'.

'in' acts as a link.
