Carriers of BSE travelling around America (5)
I believe the answer is:
buses
'carriers' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'bse travelling around america' is the wordplay.
'travelling' is an anagram indicator.
'around' indicates putting letters inside.
'america' becomes 'us' (abbreviation for the United States).
'bse' anagrammed gives 'bes'.
'bes' enclosing 'us' is 'BUSES'.
'of' is the link.
Can you help me to learn more?
(Other definitions for buses that I've seen before include "Passenger vehicles" , "Public service vehicles" , "Public transport vehicles" .)
