Woman showing passion — the fellow runs! (7)
I believe the answer is:
heather
'woman' is the definition.
'passion the fellow runs' is the wordplay.
'passion' becomes 'heat' (synonyms).
'the fellow' becomes 'he' (pronoun for a man).
'runs' becomes 'r' (cricket abbreviation).
'heat'+'he'+'r'='HEATHER'
'showing' is the link.
(Other definitions for heather that I've seen before include "Plant also called ling" , "Low shrub; mixed-colour (yarn)" , "Moorland shrub" , "Erica!" , "thing seen on the moors" .)
