Test; detailed inspection (11)
I believe the answer is:
examination
This clue is a double definition.
'test' is the first definition.
(I know that test can be written as examination)
'detailed inspection' is the second definition.
(I've seen this before)
(Other definitions for examination that I've seen before include "Test of knowledge" , "Questions" , "trial" , "Formal test" , "Test of proficiency" .)
