Elevate some of those given no blessing (7)
I believe the answer is:
ennoble
'elevate' is the definition.
(I know that ennoble is a more specific form of the action elevate)
'some of those given no blessing' is the wordplay.
'some of' says the answer is hidden in the clue.
'ENNOBLE' can be found hidden inside 'those given no blessing'.
(Other definitions for ennoble that I've seen before include "Elevate in rank" , "Elevate to peerage" , "Exalt" , "Lend dignity or honour to" , "Noel Ben (anag)" .)
