Run late, but not into siding (7)
I believe the answer is:
neutral
'siding' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'run late but not' is the wordplay.
'run late' can be anagrammed to 'NEUTRAL'.
Though, I am unsure how this is indicated.
'into' acts as a link.
Can you help me to learn more?
(Other definitions for neutral that I've seen before include "Having no personal preference" , "Not supporting or favouring either side" , "Renault (anag.)" , "In which one parks" , "Not favoring either side" .)
