So ready and willing to support English (9)

I believe the answer is:
therefore
'so' is the definition.
(I've seen this before)
'ready and willing to support english' is the wordplay.
'ready and willing' becomes 'there' (I can't explain this - if you can you should believe this answer much more).
'to' becomes 'for'.
'support' says to put letters next to each other (in a down clue, some letters hold others up).
'english' becomes 'E' (abbreviation).
'there'+'for'+'e'='THEREFORE'
Can you help me to learn more?
(Other definitions for therefore that I've seen before include "Ergo" , "Consequently - for that reason" , "In consequence" , "has a triangular formation in maths?" , "as result" .)
