'air' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'corps inspired by courage mostly getting rasher?' is the wordplay.
'corps' becomes 'c' (abbreviation).
'inspired by' is an insertion indicator (some letters breathed in or 'inspired' by others).
'courage mostly' becomes 'bak' (I can't explain this - if you can you should believe this answer much more).
'getting' means one lot of letters go next to another.
'rasher?' becomes 'bacon' (I've seen this before).
'c' placed within 'bak' is 'back'.
'back'+'bacon'='BACK BACON'
