Passion about right here? (5)
I believe the answer is:
heart
'here?' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'passion about right' is the wordplay.
'passion' becomes 'heat' (synonyms).
'about' is an insertion indicator.
'right' becomes 'r' (common abbreviation).
'heat' placed around 'r' is 'HEART'.
Can you help me to learn more?
(Other definitions for heart that I've seen before include "Cardiac courage" , "Middle" , "Decorated (cake)" , "Centre; valour" , "the name of a prison in Midlothian!" .)
