One Greek character attached to ...a burning wheel, apparently (5)
I believe the answer is:
ixion
'a burning wheel apparently' is the definition.
I can't tell whether this definition defines the answer.
'one greek character attached' is the wordplay.
'one' becomes 'i' (Roman numeral).
'greek character' becomes 'xi' (letter from the Greek alphabet).
'attached' becomes 'on' (I've seen this in other clues).
'i'+'xi'+'on'='IXION'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for ixion that I've seen before include "Long-suffering mythical king" , "free-wheeling king" , "He was bound to go round endlessly" , "King punished - bound to a wheel" , "King bound by Zeus to a turning wheel" .)
