Here's how to break it down:
* Kumusta - This is the Tagalog word for "how are you."
* Ka - This is the polite form of the second-person singular pronoun "you."
Therefore, the full phrase "kumusta ka" translates to "how are you."
You can also use "kumusta kayo" for "how are you" in the plural form, addressing multiple people. This uses the polite plural form of "you."
