Beast of burden all over its master? (5)
I believe the answer is:
llama
'beast of burden' is the definition.
(I've seen this before)
'all over its master?' is the wordplay.
I cannot really understand how this works, but
an anagram of 'all' is 'lla' which is within the answer.
'master?' could be 'ma' (Master of Arts) and 'ma' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for llama that I've seen before include "Pack carrier" , "Alpaca-like animal" , "S.American animal" , "Load-carrier" , "Wool producer" .)
