Coloured light around ancient city nerve cell? (6)
I believe the answer is:
neuron
'nerve cell?' is the definition.
(synonyms)
'coloured light around ancient city' is the wordplay.
'coloured light' becomes 'neon' (I've seen this in another clue. I am not sure about the 'coloured' bit.).
'around' means one lot of letters goes inside another.
'ancient city' becomes 'ur' (ancient Sumerian city state).
'neon' enclosing 'ur' is 'NEURON'.
Can you help me to learn more?
(Other definitions for neuron that I've seen before include "that makes for nervous transmission" , "Cell that conducts nerve impulses" , "Part of one's nervous system" , "Transmitting nerve cell" , "Impulsive thing" .)
