Ravishing sweetheart and detailing futile struggles (9)
I believe the answer is:
beautiful
'ravishing' is the definition.
(similar in meaning)
'sweetheart and detailing futile struggles' is the wordplay.
I cannot quite understand how this works, but
'sweetheart' could be 'beau' (beau can mean a sweetheart or lover) and 'beau' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for beautiful that I've seen before include "Pulchritudinous, gorgeous" , "Fine" , "Aesthetically very pleasing" , "Attractive, good-looking" , "Very pleasant to behold" .)
