Revenue from company in mine reconstruction (6)
I believe the answer is:
income
'revenue' is the definition.
(both can mean money made)
'company in mine reconstruction' is the wordplay.
'company' becomes 'co' (abbreviation).
'in' means one lot of letters goes inside another.
'reconstruction' indicates anagramming the letters (I've seen 'reconstructions' mean this).
'mine' is an anagram of 'inme'.
'co' placed into 'inme' is 'INCOME'.
'from' acts as a link.
(Other definitions for income that I've seen before include "Money gained over time" , "Remuneration or earnings" , "Money gained from work or investment" , "Money received for work or from investment" , "Remunerations, takings" .)
