Consider a beak (5)
I believe the answer is:
judge
This clue is a double definition.
'consider' is the first definition.
(thesaurus)
'a beak' is the second definition.
(thesaurus)
(Other definitions for judge that I've seen before include "Arbitrator" , "Decide a legal case" , "Assess" , "Adjudicator" , "Magistrate" .)
