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

'language' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see a link between them that I can't see?

'harry arguing endlessly' is the wordplay.
'harry' indicates anagramming the letters (harry can mean to attack or spoil).
'endlessly' means to remove the last letter.
'arguing' with its final letter removed is 'arguin'.
'arguin' anagrammed gives 'UGRIAN'.

Can you help me to learn more?

(Another definition for ugrian that I've seen is " Magyar".)
