I survive in a rail crash in the country (7)
I believe the answer is:
liberia
'the country' is the definition.
(Liberia is an example)
'i survive in a rail crash' is the wordplay.
'survive' becomes 'be' (I can't explain this - if you can you should believe this answer much more).
'in' is an insertion indicator.
'crash' indicates an anagram.
'i'+'be'='ibe'
'rail' with letters rearranged gives 'lria'.
'ibe' inserted inside 'lria' is 'LIBERIA'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for liberia that I've seen before include "Hot country" , "W African Republic" , "State" , "One of the African nations" , "West African country founded for freed slaves" .)
