And so the referee gets more, but not millions (9)
I believe the answer is:
therefore
'and so' is the definition.
(thesaurus)
'the referee gets more but not millions' is the wordplay.
'referee' becomes 'ref' ('ref' can be a synonym of 'referee').
'gets' is a charade indicator (letters next to each other).
'but not' suggests deleting specific letters.
'millions' becomes 'm' (abbreviation).
'more' with 'm' taken away is 'ore'.
'the'+'ref'+'ore'='THEREFORE'
(Other definitions for therefore that I've seen before include "as result" , "It follows" , "Consequently - for that reason" , "Thus" , "has a triangular formation in maths?" .)
