Consult the match official with hesitation (5)
I believe the answer is:
refer
'consult the match' is the definition.
'refer' can be an answer for 'consult' (thesaurus). I am unsure of the 'the match' bit.
'official with hesitation' is the wordplay.
'official' becomes 'ref' (match official in football, say).
'with hesitation' becomes 'er' (I've seen this in other clues).
'ref'+'er'='REFER'
Can you help me to learn more?
(Other definitions for refer that I've seen before include "Pertain; assign" , "Pertain or cite" , "Pass" , "Send or direct to a specialist" , "Bring up" .)
