Earliest of talents, 'Little Princess', growing up? (9)
I believe the answer is:
tweenager
'earliest of talents little princess growing up?' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'earliest of talents little princess growing up?' is the wordplay.
'earliest of' says to take the initial letters.
'little' becomes 'wee' (similar in meaning).
'princess' becomes 'regan' (character in King Lear).
'growing up?' is a reversal indicator.
The initial letter of 'talents' is 't'.
'regan' reversed gives 'nager'.
't'+'wee'+'nager'='TWEENAGER'
Can you help me to learn more?
(Other definitions for tweenager that I've seen before include "Youngster" , "adolescent" , "exasperating twelve-year-old" , "(Informally) a child approaching the age of 13?" , "Precocious child" .)
