Making one feel there's point to the cause (7)
I believe the answer is:
emotive
'making one feel' is the definition.
I can't judge whether this defines the answer.
'there's point to the cause' is the wordplay.
'there's' means one lot of letters go next to another.
'point' becomes 'e' (compass point).
'to the cause' becomes 'motive' (I can't explain this - if you can you should believe this answer much more).
'e' next to 'motive' is 'EMOTIVE'.
Can you help me to learn more?
(Other definitions for emotive that I've seen before include "Generating feelings" , "Deeply felt" , "Affecting, moving" , "Contentious" , "arousing passion" .)
