Stations Royal Marines on popular island after evacuating there (7)
I believe the answer is:
termini
'stations' is the definition.
(terminus is a kind of station)
'royal marines on popular island after evacuating there' is the wordplay.
'royal' becomes 'r' (abbreviation).
'marines on popular island' becomes 'mini' (I can't justify this - if you can you should give a lot more credence to this answer).
'after' means one lot of letters go next to another.
'evacuating' suggests removing the centre (I've seen 'evacuated' mean this).
'there' with its centre removed is 'te'.
'r'+'mini'='rmini'
'rmini' put after 'te' is 'TERMINI'.
Can you help me to learn more?
(Other definitions for termini that I've seen before include "Interim (anag.)" , "End stations" , "Some like Victoria" , "End-of-line stations" , "End points of rail or bus routes" .)
