Arrived at the corner with a beast of burden (5)
I believe the answer is:
camel
'beast of burden' is the definition.
(I've seen this in another clue)
'arrived at the corner' is the wordplay.
'arrived' becomes 'came' (come can mean to appear or arrive).
'at' says to put letters next to each other.
'the corner' becomes 'l' (I am not sure about this - if you are sure you should believe this answer much more).
'came'+'l'='CAMEL'
'with a' is the link.
Can you help me to learn more?
(Other definitions for camel that I've seen before include "Humped ungulate" , "fawn" , "Bearer of burdens" , "Desert ruminant" , "African transport" .)
