European people called out lazy jab (7)
I believe the answer is:
slovaks
'european people' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps there's an association between them I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for slovaks that I've seen before include "Europeans" , "Citizens of Bratislava, say" .)
