Believe in giving commendation (6)
I believe the answer is:
credit
This could be a double definition.
'believe in' is the first definition.
'credit' can be an answer for 'believe' (I've seen this in another clue). I am not sure about the 'in' bit.
'commendation' is the second definition.
(I know that credit is a type of commendation)
'giving' is the link.
Can you help me to learn more?
(Other definitions for credit that I've seen before include "Source of pride; account entry" , "acknowledgement of liability" , "Belief; tick" , "Believe the time allowed for payment" , "Title" .)
