Alpine sun transformed some narrow land (9)
I believe the answer is:
peninsula
'some narrow land' is the definition.
'peninsula' can be an answer for 'land' (peninsula is a kind of land). I am not certain of the 'some narrow' bit.
'alpine sun transformed' is the wordplay.
'transformed' is an anagram indicator.
'alpine'+'sun'='alpinesun'
'alpinesun' anagrammed gives 'PENINSULA'.
Can you help me to learn more?
(Other definitions for peninsula that I've seen before include "War-zone" , "Lower California, say" , "Large land-mass projecting into a body of water" , "Piece of land projecting into water" , "cape" .)
