Feature different parts of restraint (4,5)
I believe the answer is:
chin strap
'restraint' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'feature different parts' is the wordplay.
'feature' becomes 'chin' (chin is a kind of feature).
'different' indicates anagramming the letters.
'parts' is an anagram of 'strap'.
'chin'+'strap'='CHIN STRAP'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for chin strap that I've seen before include "Securer for helmet" , "Thong to hold on helmet" .)
