Somehow entrap guardian (6)
I believe the answer is:
'guardian' is the definition.
'somehow entrap' is the wordplay.
'somehow' is an anagram indicator.
'entrap' with letters rearranged gives 'PARENT'.
(Other definitions for parent that I've seen before include "Author" , "The company of which others are subsidiaries" , "Raise" , "person responsible for children" , "One with children" .)
