Bella's wrong name tabs (6)
I believe the answer is:
labels
'name tabs' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'bella's wrong' is the wordplay.
'wrong' indicates anagramming the letters.
'bellas' with letters rearranged gives 'LABELS'.
Can you help me to learn more?
(Other definitions for labels that I've seen before include "Appends a category to something or someone" , "Present tags" , "Tags; classifies" , "tags,brands" , "'Trade names, of designers say (6)'" .)
