Veil some lovers had owned (10)
I believe the answer is:
overshadow
'veil' is the definition.
(thesaurus)
'some lovers had owned' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'OVERSHADOW' is hidden within 'lovers had owned'.
(Other definitions for overshadow that I've seen before include "Cast gloom on" , "Dominate" , "Eclipse" , "Dwarf" .)
