Measure out during a time test (4)
I believe the answer is:
mete
'measure out' is the definition.
(thesaurus)
'during a time test' is the wordplay.
'during' indicates a hidden word.
'METE' is hidden within 'time test'.
(Other definitions for mete that I've seen before include "boundary" , "Measure" , "Dole (out)" , "Dish (out)" , "Administer or hand out" .)
