Honest artisan turned out to be a famous entertainer (5,7)
I believe the answer is:
frank sinatra
'entertainer' is the definition.
(I've seen this before)
'honest artisan turned out to be a famous' is the wordplay.
I cannot really understand how this works, but
'honest' could be 'frank' (similar in meaning) and 'frank' is located in the answer.
an anagram of 'artisan' is 'sinatra' which is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for frank sinatra that I've seen is " entertainer".)
