Shakespearean character who could thrive on nothing (8)
I believe the answer is:
prospero
'shakespearean character' is the definition.
'prospero' can be an answer for 'character' (I have seen 'Shakespearian character' mean 'prospero' so perhaps 'character' could also mean 'prospero'). I'm not sure about the 'shakespearean' bit.
'thrive on nothing' is the wordplay.
'thrive' becomes 'prosper' (synonyms).
'on' is a charade indicator (letters next to each other).
'nothing' becomes 'O' (O resembles 0).
'prosper'+'o'='PROSPERO'
'who could' acts as a link.
Can you help me to learn more?
(Other definitions for prospero that I've seen before include "stage hero" , "magician on stage" , "29 9 [TEMPEST CHARACTER]" , "Role in The Tempest" , "Shakespearean magician" .)
