Analyse, test (7)
I believe the answer is:
examine
This clue is a double definition.
'analyse' is the first definition.
(I know that analyse can be written as examine)
'test' is the second definition.
(I know that test can be written as examine)
(Other definitions for examine that I've seen before include "Question (a witness)" , "Question closely" , "Appraise" , "research" , "Test or study carefully" .)
