Refuse to give credit? (10)
I believe the answer is:
disbelieve
'refuse' is the definition.
Although both the answer and definition are verbs in their base form, I cannot understand how one could define the other.
'give credit?' is the wordplay.
'give' becomes 'dis' (I am not sure about this - if you are sure you should believe this answer much more).
'credit?' becomes 'believe' (I've seen this before).
'dis'+'believe'='DISBELIEVE'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for disbelieve that I've seen before include "Mistrust" , "Have no faith (in)" .)
