Look it up, either way (5)
I believe the answer is:
refer
'either way' is the definition.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for refer that I've seen before include "Send or direct to a specialist" , "Freer (anag.)" , "Send a patient to a specialist" , "Make allusion, or turn to for information" , "Pertain or cite" .)
