Turn for information - up or down (5)
I believe the answer is:
This might be a double definition.
'turn for information' is the first definition.
'refer' can be an answer for 'turn' (thesaurus). I'm not certain of the 'for information' bit.
'up or down' is the second definition.
Can you help me to learn more?
(Other definitions for refer that I've seen before include "Make an allusion, or send on" , "Allude, assign" , "Turn to (for information, authorisation etc)" , "Send a patient to a specialist" , "Pass" .)
