How many countries in the world speak latin?

It's a little tricky to give a precise number of countries that "speak Latin". Here's why:

* Latin is a dead language: While Latin was once a living language spoken throughout the Roman Empire, it's no longer spoken as a primary language in any country.

* Romance Languages: Latin is the ancestor of many modern languages, including Spanish, French, Italian, Portuguese, Romanian, Catalan, and others. These languages are spoken in many countries.

* Church Latin: Latin is still used in some religious contexts, particularly in the Catholic Church.

So, to answer your question in a way that is accurate:

* No countries speak Latin as a primary language.

* Many countries speak Romance languages, which evolved from Latin.
