Give good review to former group making comeback (5)
I believe the answer is:
extol
'give good review to' is the definition.
I can't tell whether this definition defines the answer.
'former group making comeback' is the wordplay.
'former' becomes 'ex' (prefix meaning former or onetime).
'group' becomes 'lot'.
'making comeback' says the letters should be written in reverse.
'lot' reversed gives 'tol'.
'ex'+'tol'='EXTOL'
Can you help me to learn more?
(Other definitions for extol that I've seen before include "Acclaim" , "Praise highly, laud" , "Exalt" , "Praise with enthusiasm" , "Highly rate" .)
