Pained noise from horse briefly stopping Grand National (5)
I believe the answer is:
groan
'pained noise' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'horse briefly stopping grand national' is the wordplay.
I cannot quite understand how this works, but
'horse' could be 'roan' (roan is a kind of horse) and 'roan' is found within the answer.
'grand' could be 'g' (G is short for grand as in a thousand) and 'g' is located in the answer.
No letters remain.
This explanation may well be incorrect...
'from' is the link.
Can you help me to learn more?
(Other definitions for groan that I've seen before include "Cry of pain or despair" , "Sound of pain or disapproval" , "express disapproval" , "Sound of one in pain" , "Expression of pain or disapproval" .)
