Having no standing around railway without connection (9)
I believe the answer is:
unrelated
'having no standing' is the definition.
I can't tell whether this defines the answer.
'railway without connection' is the wordplay.
'railway' becomes 'el' (El train, short for elevated railway).
'without' is an insertion indicator (some letters go outside or 'without' others).
'connection' becomes 'unrated' (I can't explain this - if you can you should believe this answer much more).
'el' placed within 'unrated' is 'UNRELATED'.
'around' acts as a link.
Can you help me to learn more?
(Other definitions for unrelated that I've seen before include "Not linked" , "Irrelevant" , "Having no (family) connection" , "beside the point" .)
