Bother reversing error of ravishing youth (6)
I believe the answer is:
adonis
'ravishing youth' is the definition.
'adonis' can be an answer for 'youth' (I have seen 'Handsome youth' mean 'adonis' so perhaps 'youth' could also mean 'adonis'). I am not sure about the 'ravishing' bit.
'bother reversing error' is the wordplay.
'bother' becomes 'ado' (both can mean fuss or commotion).
'reversing' shows that the letters should be reversed in order.
'error' becomes 'sin' (a sin is a moral error).
'sin' written backwards gives 'nis'.
'ado'+'nis'='ADONIS'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for adonis that I've seen before include "Type of male beauty" , "In Greek myth, handsome youth beloved of Aphrodite" , "striking youth" , "No aids (anag)" , "A very good-looking ancient Greek" .)
