She infamously distressed her lover (7)
I believe the answer is:
delilah
'lover' is the definition.
(I know that Delilah is a fancy woman)
'she infamously distressed her' is the wordplay.
I cannot really see how this works, but
'she' could be 'delila' and 'delila' is located in the answer.
A single letter 'h' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for delilah that I've seen before include "Woman linked to Samson" , "Samson's destroyer" , "Dangerous temptress - Samson's girlfriend" , "She tempted" , "Samson's treacherous girl friend" .)
