Desire without passion, nominally (3)
I believe the answer is:
des
'nominally' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'desire without passion' is the wordplay.
'without' is a deletion indicator.
'passion' becomes 'ire' (ire is passionate anger).
'desire' with 'ire' removed is 'DES'.
Can you help me to learn more?
(Other definitions for des that I've seen before include "- O'Connor, Br. singer" , "and 9 Across: Former 'Countdown' host" .)
