Woman priest, one giving orders? (8)
I believe the answer is:
director
'one giving orders?' is the definition.
'woman priest' is the wordplay.
'woman' becomes 'di' (short for Diana).
'priest' becomes 'rector' (I've seen this before).
'di'+'rector'='DIRECTOR'
(Other definitions for director that I've seen before include "He makes films or runs companies" , "One who controls resources and expenditures" , "Company board member" , "Creditor made to create film or play" , "Controller of production or member of a board" .)
