Let race run out of daughter's complex (7)
I believe the answer is:
electra
'daughter's complex' is the definition.
'Electra' can be an answer for 'complex' (Electra complex is an example). I am not certain of the 'daughter's' bit.
'let race run' is the wordplay.
'run' indicates anagramming the letters.
'let'+'race'='letrace'
'letrace' is an anagram of 'ELECTRA'.
'out of' acts as a link.
Can you help me to learn more?
(Other definitions for electra that I've seen before include "Agamemnon's child" , "type of complex" , "Greek heroine (with a complex!)" , "Greek mythic woman has an odd Celt ear" , "legendary Greek daughter" .)
