Talk to which a peculiar ending was given (5)

Ross

I believe the answer is:

argot

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

'talk' is the definition.
(I have seen 'Talk of thieves' mean 'argot' so perhaps 'talk' could also mean 'argot')

'a peculiar ending was given' is the wordplay.
'ending' says to take the final letters (the ending of the word).
'was given' becomes 'got' (I can't explain this - if you can you should give a lot more credence to this answer).
The last letter of 'peculiar' is 'r'.
'a'+'r'+'got'='ARGOT'

'to which' is the link.

Can you help me to learn more?

(Other definitions for argot that I've seen before include "secret language" , "manner of speaking" , "Special jargon of a group" , "Talk of thieves" , "Particular group's jargon" .)
