In atlas I found the people of one European country (8)
I believe the answer is:
italians
'people of one european country' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'in atlas i found' is the wordplay.
'in atlas i' anagrams to 'ITALIANS'.
Though, I'm unsure how this is indicated.
'the' is the link.
Can you help me to learn more?
(Other definitions for italians that I've seen before include "Natives of Tuscany, say" , "Romans, Florentines, etc." .)
