Conclude ultimately that women supply dowry? (9)
I believe the answer is:
endowment
'dowry?' is the definition.
(thesaurus)
'conclude ultimately that women supply' is the wordplay.
'conclude' becomes 'end' (I've seen this in another clue).
'ultimately' says to take the final letters.
'supply' indicates anagramming the letters (in a supple way).
The last letter of 'that' is 't'.
't'+'women'='twomen'
'twomen' with letters rearranged gives 'owment'.
'end'+'owment'='ENDOWMENT'
(Other definitions for endowment that I've seen before include "Grant" , "Bequeathed income" , "Income/property settled on person/institution" , "source of income" , "Personal quality - type of mortgage" .)
