You don't need to really know the language to follow the Latin Mass; you can just follow along in the missal; Latin is the left column, English is the right. (Pretty easy for English speakers; the alphabet is the same. Probably harder for people in, e.g., Japan.) You learn bits and pieces just by osmosis anyway.
If you really want to learn the language, most any college or university has a classics department that teaches Latin. (I actually took a year in high school* and then two years in college.) They teach classical Latin, which has some modest differences in pronunciation and grammar from ecclesiastical Latin, but that's not a big problem.
*It was a public high school in the late 1970's. For fun just before Christmas break, we read the Christmas story in St. Luke's gospel from the Latin Vulgate Bible. How shocking and scandalous is that?

Well, this woman said:
“I can go to Mass in China or Italy, or America or Japan, and anywhere else in the World, and, if it’s in Latin, I can understand and join in, because that’s how I was raised.”
Do the missals in these countries also include English in their columns and other languages? If not, then she’s got to be multilingual to be able to follow it.
Should have read "... modest differences in pronunciation and vocabulary from ...".
