She left the day I got into trouble (5)
I believe the answer is:
lydia
'she' is the definition.
(woman's name)
'left the day i got into trouble' is the wordplay.
'left' says the letters should be written backwards.
'the day i' becomes 'dy' (I am not sure about this - if you are sure you should believe this answer much more).
'got into' indicates putting letters inside.
'trouble' becomes 'ail' (synonyms).
'dy' put within 'ail' is 'aidyl'.
'aidyl' backwards is 'LYDIA'.
Can you help me to learn more?
(Other definitions for lydia that I've seen before include "where Croesus was king" , "lady" , "Woman" , "Female" , "girl" .)
