Passion and fight oddly saved match (6)
I believe the answer is:
warmth
'passion' is the definition.
(I know that passion can be written as warmth)
'fight oddly saved match' is the wordplay.
'fight' becomes 'war' (warring is a kind of fighting).
'oddly saved' indicates alternate letters (letters in odd-numbered positions removed).
The alternate letters of 'match' are 'mth'.
'war'+'mth'='WARMTH'
'and' acts as a link.
(Other definitions for warmth that I've seen before include "Ardour" , "Mild heat" , "Compassion" , "Cosiness or enthusiasm" , "Cordiality" .)
