Limitless neon wasting energy at train station (7)
I believe the answer is:
nonstop
'limitless' is the definition.
Both the definition and answer are adjectives. Maybe there's a link between them I don't understand?
'neon wasting energy at train station' is the wordplay.
'wasting' is a deletion indicator.
'energy' becomes 'e' (physics symbol as in E=mc2).
'at' says to put letters next to each other.
'train station' becomes 'stop' (I've seen this in another clue).
'neon' with 'e' taken away is 'non'.
'non'+'stop'='NONSTOP'
Can you help me to learn more?
(Other definitions for nonstop that I've seen before include "(Of a flight) direct" , "Relentless" , "Round-the-clock, unceasing" , "Around-the-clock" , "Ceaseless" .)
