Sobers quit using pseudonyms (10)

I believe the answer is:

sobriquets

I'm a little stuck... Click here to teach me more about this clue!

'pseudonyms' 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?

'sobers quit using' is the wordplay.
'using' is an anagram indicator (the letters used in a different way).
'sobers'+'quit'='sobersquit'
'sobersquit' with letters rearranged gives 'SOBRIQUETS'.

Can you help me to learn more?
