Trojan Women perhaps grew old in Troy, lacking nothing (7)
I believe the answer is:
tragedy
'trojan women perhaps grew' is the definition.
I can't tell whether this definition defines the answer.
'old in troy lacking nothing' is the wordplay.
'old' becomes 'aged' (similar in meaning).
'in' indicates putting letters inside.
'lacking' indicates named letters should be taken away.
'nothing' becomes 'O' (looks like zero - 0).
'troy' with 'o' taken out is 'try'.
'aged' going into 'try' is 'TRAGEDY'.
Can you help me to learn more?
(Other definitions for tragedy that I've seen before include "Calamity, disaster" , "play such as Electra" , "Calamity as in sad play" , "Play with a gloomy finish" , "Hamlet, say" .)
