Uses clues and unearths true combination (8,4)
I believe the answer is:
treasure hunt
'uses clues and' is the definition.
I can't tell whether this definition defines the answer.
'unearths true combination' is the wordplay.
'combination' indicates anagramming the letters.
'unearths'+'true'='unearthstrue'
'unearthstrue' anagrammed gives 'TREASURE HUNT'.
Can you help me to learn more?
(Other definitions for treasure hunt that I've seen before include "Exciting quest" , "Game searching for hidden objects" , "as recent London marchers apparently do?" , "Children's party game where things are sought" , "Solving clues for prize" .)
