Have recourse to the match official? (5)
I believe the answer is:
refer
'have recourse to' is the definition.
(thesaurus)
'match official?' is the wordplay.
I cannot really see how this works, but
'official?' could be 'ref' (match official in football, say) and 'ref' is present in the answer.
The remaining letters 'er' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'the' is the link.
Can you help me to learn more?
(Other definitions for refer that I've seen before include "Pertain; assign" , "Freer (anag.)" , "Mention/allude (to)" , "Bring up" , "guide" .)
