Here's why:
* Sibuyas is the general word for "onion" in Tagalog.
* Tagalog refers to a specific type of onion, which is usually what shallots are referred to as in the Philippines.
You may also sometimes hear sibuyas na pranses, which means "French onion." This term is less common but still used by some people.
It's important to note that while "sibuyas tagalog" is the most common translation, there isn't a single, universally accepted term for shallots in Tagalog. However, it's the most accurate and widely understood way to refer to them.
