Travelling people transported it to USSR (8)
I believe the answer is:
tourists
'travelling people' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps you can see an association between them that I don't see?
'transported it to ussr' is the wordplay.
'transported' is an anagram indicator.
'it'+'to'+'ussr'='ittoussr'
'ittoussr' is an anagram of 'TOURISTS'.
Can you help me to learn more?
(Other definitions for tourists that I've seen before include "Visitors and sightseers" , "Holiday-makers from abroad" , "They travel for pleasure" , "Group of visitors" .)
