True dears should be cherished (9)
I believe the answer is:
'be cherished' is the definition.
'true dears should' is the wordplay.
'true dears' can be anagrammed to 'TREASURED'.
But, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for treasured that I've seen before include "Valued" , "Prized, precious" , "Darling" , "thought highly of" , "Much-valued" .)
