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

'chaps near rye' is the definition.
I know nothing about this answer so I can't judge whether this works.

'big liar wore' is the wordplay.
'big liar wore' can be anagrammed to 'BLAIRGOWRIE'.
But, I am unsure how this is indicated.

Can you help me to learn more?
