Criminal alleges European is talk of bar (8)

Ross

I believe the answer is:

legalese

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

'talk of bar' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'criminal alleges european' is the wordplay.
'criminal' indicates anagramming the letters.
'european' becomes 'E' (abbreviation e.g. EU).
'alleges' is an anagram of 'legales'.
'legales'+'e'='LEGALESE'

'is' is the link.

Can you help me to learn more?

(Other definitions for legalese that I've seen before include "Special terms" , "formal language" , "contract wording?" , "such language at the bar!" , "Bar talk" .)
