Man's chin also wobbled (8)
I believe the answer is:
nicholas
'man's' is the definition.
'chin also wobbled' is the wordplay.
'wobbled' indicates anagramming the letters (I've seen 'wobbling' mean this).
'chin'+'also'='chinalso'
'chinalso' is an anagram of 'NICHOLAS'.
(Other definitions for nicholas that I've seen before include "Boy" , "Saint identified as Santa Claus" , "Patron saint of Greece (and Liverpool)" , "Former Russian leader" , "Man's name; last tsar" .)
