It's important to note that:
* Sherpa is not a dialect of Tibetan, but a separate language within the Tibetic language family.
* Most Sherpa people are also fluent in Nepali, the official language of Nepal.
* Other languages spoken by Sherpa people include English and other regional languages depending on their location.
While Sherpa is their primary language, the ability to speak Nepali is crucial for integration into Nepalese society and for interacting with the broader community.
