What is the meaning of Punjabi word kharku?

"Kharku" is not a common Punjabi word. It's possible that you might have heard it mispronounced or it's a very regional term.

It's important to note that Punjabi, like many languages, has a wide range of dialects and local variations.

To get a more accurate understanding, I need more information:

* Could you provide the context in which you heard "kharku"? What was the speaker talking about?

* Do you know where the speaker is from? This could help narrow down the dialect.

Once I have more information, I may be able to offer a more helpful answer.
