Some man, a cleanskin, bore restraint (7)
I believe the answer is:
manacle
'restraint' is the definition.
(I know that manacle is a type of restraint)
'some man a cleanskin bore' is the wordplay.
I cannot really understand how this works, but
'some' could be 'a' and 'a' is present in the answer.
an anagram of 'man' is 'mna' which is within the left over letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for manacle that I've seen before include "item restricting movement" , "restricting at the cuff?" , "Curb" , "Handcuff" , "Metal shackle" .)
