Edward, our sovereign, showed passions (7)

I believe the answer is:

ardours

'passions' is the definition.
(ardour is a kind of passion)

'edward our sovereign showed' is the wordplay.
'showed' indicates a hidden word (I've seen 'show' mean this).
'ARDOURS' can be found hidden inside 'edward our sovereign'.

I've seen this clue in The Guardian.
