It's vital I answer piece describing some European people (8)
I believe the answer is:
italians
'some european people' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Maybe you can see a link between them that I don't see?
'it's vital i answer piece' is the wordplay.
'piece' indicates the answer is hidden within the clue.
'ITALIANS' is hidden in the letters of 'ts vital i answer'.
'describing' is the link.
Can you help me to learn more?
(Other definitions for italians that I've seen before include "Romans, Florentines, etc." , "Natives of Tuscany, say" .)
