Measure, old-style (4)
I believe the answer is:
'measure old-style' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mete that I've seen before include "Dish (out)" , "Give as due - say punishment" , "boundary" , "To - out is to dispense (eg, justice)" , "Administer or bestow, as in small portions" .)
