Good person, mature, with yen that's exaggerated (6)
I believe the answer is:
stagey
'exaggerated' is the definition.
Both the definition and answer are adjectives.
Perhaps you can see a link between them that I don't see?
'good person mature with yen' is the wordplay.
'good person' becomes 'st' (saint).
'mature' becomes 'age' (synonyms).
'with' says to put letters next to each other.
'yen' becomes 'y' (resembles the symbol for the currency of Japan).
'st'+'age'+'y'='STAGEY'
'that's' is the link.
Can you help me to learn more?
(Other definitions for stagey that I've seen before include "camp" , "Much too theatrical" , "may be exaggerated" , "Excessively dramatic" .)
