Tragic girl chosen to join Royal Academy (7)
I believe the answer is:
electra
'tragic girl' is the definition.
'Electra' can be an answer for 'girl'. I'm not certain of the 'tragic' bit.
'chosen to join royal academy' is the wordplay.
'chosen' becomes 'elect' ('elect' as an adjective can mean chosen).
'to join' says to put letters next to each other.
'royal academy' becomes 'RA'.
'elect'+'ra'='ELECTRA'
Can you help me to learn more?
(Other definitions for electra that I've seen before include "female in tragedy" , "complex character" , "titled lady" , "Daughter of Agamemnon and Clytemnestra (who has a complex?)" , "It's a kind of complex" .)
