It's a very common word used in everyday conversation. It's pronounced similarly to the English word "ya" but with a slightly softer "y" sound.
Here are some examples of how it's used:
* "Ya, main aa gaya." (Yes, I have come.)
* "Ya, tusi sahi keh rahe ho." (Yes, you are right.)
* "Ya, main khana kha chukka." (Yes, I have eaten.)
It's important to note that there might be slight variations in pronunciation depending on the region and dialect. However, "ya" is generally understood as "yes" throughout the Punjabi language.
