Finish - a sentence? (3,1,4,2)
I believe the answer is:
put a stop to
'sentence?' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'finish a' is the wordplay.
I cannot really understand how this works, but
'finish' could be 'stop' (synonyms) and 'stop' is found in the answer.
'a' is found in the answer.
The remaining letters 'putto' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for put a stop to that I've seen is " Cause to end".)
