Yeti wanders around some blasted mountain wilderness (8)
I believe the answer is:
yosemite
'mountain wilderness' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'yeti wanders around some blasted' is the wordplay.
'wanders' is an anagram indicator.
'around' is an insertion indicator.
'blasted' indicates anagramming the letters.
'yeti' anagrammed gives 'yite'.
'some' anagrammed gives 'osem'.
'yite' placed around 'osem' is 'YOSEMITE'.
Can you help me to learn more?
(Other definitions for yosemite that I've seen before include "Natl. Park in California" , "US National Park in California" , "Where there are watery cascades" , "Area of beauty" , "Californian national park" .)
