The nude ran, wobbling below (10)
I believe the answer is:
underneath
'below' is the definition.
(thesaurus)
'the nude ran wobbling' is the wordplay.
'wobbling' is an anagram indicator.
'the'+'nude'+'ran'='thenuderan'
'thenuderan' with letters rearranged gives 'UNDERNEATH'.
(Other definitions for underneath that I've seen before include "Lower" , "on the hidden side" , "bottom" .)
