means A chemically inert noble gas that glows bright orange-red when electrified, famous for lighting up signs and city nights.

from From the Greek 'neon,' meaning 'new' — the neuter form of 'neos.' When chemists Ramsay and Travers isolated it in 1898, the story goes that Ramsay's young son suggested 'novum' (Latin for 'new'), and his father reshaped the idea into Greek instead, naming the gas simply 'the new one.'
