Lively female with yen to embrace danger (6)
I believe the answer is:
frisky
'lively' is the definition.
(I've seen this before)
'female with yen to embrace danger' is the wordplay.
'female' becomes 'f' (common abbreviation).
'with' means one lot of letters go next to another.
'yen' becomes 'y' (resembles the symbol for the currency of Japan).
'to embrace' means one lot of letters goes inside another.
'danger' becomes 'risk' (synonyms).
'f'+'y'='fy'
'fy' placed around 'risk' is 'FRISKY'.
(Other definitions for frisky that I've seen before include "Energetically playful" , "Lively like playful dog" , "Playful, full of energy" , "Frolicsome" , "In high spirits" .)
