Mountain-dwelling person begins to improvise after plane crash (6)
I believe the answer is:
nepali
'mountain-dwelling person' is the definition.
I can't judge whether this definition defines the answer.
'begins to improvise after plane crash' is the wordplay.
'begins to' says to take the initial letters (I've seen 'beginning to' mean this).
'after' means one lot of letters go next to another.
'crash' indicates an anagram.
The initial letter of 'improvise' is 'i'.
'plane' with letters rearranged gives 'nepal'.
'i' put after 'nepal' is 'NEPALI'.
Can you help me to learn more?
(Other definitions for nepali that I've seen before include "Native of one Himalayan state" , "one found in mountainous region" , "Foreigner" , "Mountain-dweller" , "Language of Kathmandu" .)
