Dobbin's reaction to a hinge breaking? (5)
I believe the answer is:
neigh
'dobbin's reaction' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'a hinge breaking?' is the wordplay.
'breaking?' is an anagram indicator.
'hinge' anagrammed gives 'NEIGH'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for neigh that I've seen before include "Mare's cry, e.g." , "Whinnying sound" , "Whinnying noise" , "Horse's cry" , "beastly noise" .)
