New term for dispensing with borders in transport system (5)
I believe the answer is:
metro
'transport system' is the definition.
(I've seen this before)
'new term for dispensing with' is the wordplay.
'new' indicates an anagram.
'for' is a charade indicator (letters next to each other).
'dispensing with' becomes 'o' (I can't explain this - if you can you should give a lot more credence to this answer).
'term' is an anagram of 'metr'.
'metr'+'o'='METRO'
'borders in' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for metro that I've seen before include "Parisian underground railway" , "The underground railway system in Paris" , "what moves many Parisians" , "Urban railway system" , "Paris subway" .)
