Rest vase on an article, somewhere high up (9)
I believe the answer is:
annapurna
'somewhere high up' is the definition.
I can't tell whether this definition defines the answer.
'rest vase on an article' is the wordplay.
'rest' becomes 'nap' (I've seen this in another clue).
'vase' becomes 'urn' (urn is a kind of vase).
'on' says to put letters next to each other.
'article' becomes 'a' (the indefinite article in English).
'nap'+'urn'='napurn'
'napurn' after 'an' is 'annapurn'.
'annapurn'+'a'='ANNAPURNA'
Can you help me to learn more?
(Other definitions for annapurna that I've seen before include "Himalayan peak; Hindu goddess of plenty" , "Range" , "high ridge" .)
