Sample; example (8)
I believe the answer is:
specimen
I believe this clue is a double definition.
'sample' is the first definition.
(I know that specimen is a type of sample)
'example' is the second definition.
(I know that specimen is a type of example)
(Other definitions for specimen that I've seen before include "blood sample" , "Copy" , "Example of type" , "Test sample" , "Derogatory description of person" .)
