Praise brief review journalist penned (6)
I believe the answer is:
credit
'praise' is the definition.
(I've seen this before)
'brief review journalist penned' is the wordplay.
'brief review' becomes 'crit' (abbreviation for 'criticism').
'journalist' becomes 'ed' (short for editor).
'penned' means one lot of letters goes inside another (inserted letters are enclosed or penned in).
'crit' going around 'ed' is 'CREDIT'.
(Other definitions for credit that I've seen before include "Believe; account entry" , "Add (money) to account" , "gives you a good result in examination" , "Positive bank balance" , "Acknowledgement given for deed or quality" .)
