Cried movingly at the perfect ending, we believe (6)
I believe the answer is:
credit
'believe' is the definition.
(I've seen this before)
'cried movingly at the perfect ending we' is the wordplay.
I cannot really see how this works, but
an anagram of 'cried' is 'credi' which is located in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for credit that I've seen before include "Side of an account for payments in" , "Believe - one side of an account" , "good grade" , "Distinction -- attribute" , "Time to pay, or due recognition" .)
