What is the Tagalog translation of oak tree?

There's no direct one-to-one translation for "oak tree" in Tagalog. The closest equivalent would be "puno ng kahoy" which literally means "tree of wood".

However, if you want to be more specific and emphasize that it's an oak tree, you can use these options:

* "Puno ng encina" - This translates to "oak tree" but it uses the Spanish word for oak.

* "Puno ng kahoy na oak" - This is a more literal translation, meaning "tree of oak wood".

Ultimately, the best translation depends on the context and the desired level of formality.
