Gave out (caught), left in, left out (8)
I believe the answer is:
excluded
'left out' is the definition.
('exclude' can be a synonym of 'leave out')
'gave out caught left in' is the wordplay.
'gave out' becomes 'exuded'.
'caught' becomes 'c' (cricket abbreviation).
'left' becomes 'L' (common abbreviation).
'in' means one lot of letters goes inside another.
'c'+'l'='cl'
'exuded' enclosing 'cl' is 'EXCLUDED'.
(Other definitions for excluded that I've seen before include "Kept out from place or group" , "Left out" , "Denied access" , "Ruled out" , "'Debarred, shut out (8)'" .)
