Wants one to enter nice house (7)
I believe the answer is:
desires
'wants' is the definition.
('desire' can be a synonym of 'want')
'one to enter nice house' is the wordplay.
I cannot really see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found in the answer.
The remaining letters 'desres' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for desires that I've seen before include "Covets and yearns for" , "Wishes" , "Wants (7)." , "needs" , "Hopes" .)
