Confirm what might be Arabs uncovered after death (7)
I believe the answer is:
endorse
'confirm' is the definition.
(thesaurus)
'might be arabs uncovered after death' is the wordplay.
I cannot really see how this works, but
'be' could be 'end' (ending is a kind of being) and 'end' is found within the answer.
This explanation may well be incorrect...
'what' acts as a link.
Can you help me to learn more?
(Other definitions for endorse that I've seen before include "Corroborate" , "Red ones (anag.)" , "Give support or approval to" , "Say you approve" , "Rubber-stamp" .)
