Rise of number one team, one bound to be permanently revolutionary (5)
I believe the answer is:
ixion
'permanently revolutionary' is the definition.
The definition suggests a singular noun which matches the answer.
'rise of number one team one bound' is the wordplay.
'rise of' says the letters should be written backwards (in a down clue, letters go up).
'number' becomes 'no' (abbreviation).
'one' becomes 'i' (Roman numeral).
'team' becomes 'XI' (a football team, from Roman numerals for ii).
'one bound' is an insertion indicator.
'no'+'i'='noi'
'noi' backwards is 'ion'.
'ion' enclosing 'xi' is 'IXION'.
'to be' is the link.
Can you help me to learn more?
(Other definitions for ixion that I've seen before include "Long-suffering mythical king" , "He was bound to go round endlessly" , "King bound by Zeus to a turning wheel" , "free-wheeling king" , "King punished by Zeus for his love of Hera" .)
