Coming from boozer, Matthew in mountain resort (7)
I believe the answer is:
zermatt
'mountain resort' is the definition.
'zermatt' can be an answer for 'resort' (I have seen 'Swiss resort' mean 'zermatt' so perhaps 'resort' could also mean 'zermatt'). I'm not sure about the 'mountain' bit.
'coming from boozer matthew in' is the wordplay.
'coming from' says the answer is hidden in the clue.
'ZERMATT' is hidden in the letters of 'boozer matthew in'.
Can you help me to learn more?
(Other definitions for zermatt that I've seen before include "Swiss skiing resort" , "Matterhorn ski resort" , "Alpine ski resort" , "Swiss alpine resort" , "Swiss ski resort" .)
