What is the Latin word for science?

There isn't one single Latin word that perfectly translates to "science" in its modern meaning. However, the closest Latin terms are:

* scientia: This literally means "knowledge" or "understanding" and is the root of the English word "science." It was often used to refer to a systematic body of knowledge, but not necessarily in the modern, empirical sense.

* ars: This translates to "art" or "skill," and was sometimes used to refer to practical knowledge or a craft.

* philosophia naturalis: This translates to "natural philosophy," and was the term used in antiquity for what we now call science. It encompassed the study of the natural world.

So, depending on the specific context, you could use one of these Latin terms to refer to "science." However, it's important to note that these terms don't carry the same precise meaning as the English word "science."
