Sound of a hinge breaking? (5)
I believe the answer is:
neigh
'sound' is the definition.
(neigh is a kind of sound)
'a hinge breaking?' is the wordplay.
'breaking?' is an anagram indicator.
'hinge' is an anagram of 'NEIGH'.
'of' acts as a link.
(Other definitions for neigh that I've seen before include "heard on the farm" , "Whicker" , "Sound coming from Ben Nevis" , "Comment from stallion" , "Cry coming from mount" .)
