Classical Tibetan:
* གསུམ་ (sum) - This is the most common and formal way to say "3."
Modern Tibetan:
* སུམ་ (sum) - This is the more informal pronunciation of "གསུམ་."
* གསུམ (sum) - This pronunciation is still common in some regions.
* སཱམ་ (sam) - This pronunciation is used in some dialects, especially in the Kham region.
Note: The spelling of Tibetan words is based on the Tibetan writing system, which uses a unique set of characters. The pronunciation can vary slightly depending on the region and dialect.
It's important to be aware of these nuances when learning Tibetan.
