English reason for showing a lot of feeling (7)
I believe the answer is:
emotive
'showing a lot of feeling' is the definition.
(I've seen this in another clue)
'english reason' is the wordplay.
'english' becomes 'E' (abbreviation).
'reason' becomes 'motive' (I've seen this before).
'e'+'motive'='EMOTIVE'
'for' is the link.
(Other definitions for emotive that I've seen before include "Contentious" , "Generating feelings" , "Showing feelings" , "Highly-charged" , "Arousing great feeling" .)
