Glower half-way through Eugene Onegin (4)
I believe the answer is:
neon
'glower' is the definition.
(gas which glows)
'through eugene onegin' is the wordplay.
'through' says the answer is hidden in the clue.
'NEON' is hidden within 'eugene onegin'.
'half-way' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for neon that I've seen before include "One of the six inert gases" , "Gaseous element, in advertising sign say" , "Noble gas used in illuminated signs" , "Element 10, used in lights" , "Small plant; colour" .)
