Depends on your computer. Mine is a Mac with Sherlock on it. You can identify it on the work bar with a silly looking hat and a magnifying glass. Click on it when it opens up click on translations. There are several languages there. Type in you statement and the computer transtates it. No Latin. Unless you buy the software. If you don't have a Mac look for some software that will do the job. USA Computer should be able to help you out. Maybe even Best Buy.
