Originally shot and wounded outside southern military college (9)
I believe the answer is:
sandhurst
'military college' is the definition.
(British military academy)
'originally shot and wounded outside southern' is the wordplay.
'originally shot' becomes 'sand' (I can't justify this - if you can you should give a lot more credence to this answer).
'and' means one lot of letters go next to another.
'wounded' becomes 'hurt' (synonyms).
'outside' means one lot of letters goes inside another.
'southern' becomes 's' (abbreviation).
'hurt' placed around 's' is 'hurst'.
'sand'+'hurst'='SANDHURST'
Can you help me to learn more?
(Other definitions for sandhurst that I've seen before include "Seat of the Royal Military Academy" , "Military college at Camberley, Surrey" , "Training college" , "Village in Berkshire - military academy" .)
