Save some income missing a million somehow (9)
I believe the answer is:
economise
'save' is the definition.
(I've seen this before)
'some income missing a million somehow' is the wordplay.
'missing' is a deletion indicator.
'a million' becomes 'm' (abbreviation).
'somehow' indicates anagramming the letters.
'some'+'income'='someincome'
'someincome' with 'm' taken out is 'soeincome'.
'soeincome' is an anagram of 'ECONOMISE'.
(Other definitions for economise that I've seen before include "make cuts" , "budget" , "Cut back on expenses, be thrifty" , "save?" , "Scrimp" .)
