grays inn

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

'lot of barristers' is the definition.
The definition suggests a singular noun which matches the answer.

'criminal is angry with new' is the wordplay.
'criminal' is an anagram indicator.
'with' is an insertion indicator.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'is'+'angry'='isangry'
'isangry' anagrammed gives 'graysin'.
'graysin' placed around 'n' is 'GRAYS INN'.

Can you help me to learn more?
