Is there any Tagalog word for coral?

There isn't a single, universally accepted Tagalog word for "coral." However, depending on the context, you can use a few different options:

* "Sanhi" - This is a more general term referring to "shellfish" or "sea creatures with shells." It can be used to describe coral, especially when discussing its use as a material.

* "Koral" - This is the direct borrowing from the Spanish word "coral." While not a traditional Tagalog word, it's understood and used in many contexts.

* "Bato ng dagat" - This translates to "sea stone" and can be used to describe coral, especially when referring to its appearance or geological formation.

* "Pulo ng koral" - This translates to "coral island" and refers to an island formed from coral reefs.

The best word to use will depend on the specific context and your desired level of formality.

For example, you could say:

* "Ang sanhi ay mahalagang bahagi ng ekosistema sa dagat." (Coral is an important part of the marine ecosystem.)

* "Gawa sa koral ang mga alahas na ito." (These jewels are made from coral.)

* "Ang mga bato ng dagat ay magaganda at marupok." (Sea stones are beautiful and fragile.)

* "Maraming mga pulo ng koral sa Pilipinas." (There are many coral islands in the Philippines.)
