Reject lure (4,3)
I believe the answer is:
rule out
'reject' is the definition.
(thesaurus)
'lure' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'lure' is 'rule' which is located in the answer.
The remaining letters 'out' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for rule out that I've seen before include "Exclude as a possibility" , "Eliminate from consideration - using drawing stick?" , "Decide against" , "discount" , "Exclude as irrelevant or inadmissible" .)
