Buddhist priest about fifty - one that comes from Peru (5)
I believe the answer is:
llama
'one that comes from peru' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'buddhist priest about fifty' is the wordplay.
'buddhist priest' becomes 'lama' (as in the Dalai Lama).
'about' says to put letters next to each other.
'fifty' becomes 'L' (Roman numeral).
'lama' after 'l' is 'LLAMA'.
Can you help me to learn more?
(Other definitions for llama that I've seen before include "South American carrier" , "Woolly Andean animal" , "Peruvian transportation" , "mammal that chews cud" , "one that ruminates" .)
