Jack in Tara is excluded (5)
I believe the answer is:
raise
'jack' is the definition.
(I know this)
'in tara is excluded' is the wordplay.
'in' indicates the answer is hidden within the clue.
'RAISE' is hidden within 'tara is excluded'.
(Other definitions for raise that I've seen before include "Uplift" , "Collect - increase in pay" , "Advance" , "Put up" , "Wage increase" .)
