PROVO — Lillian Zarndt is no ordinary high school teacher. First off, there are the pink heels with rhinestone buckles. Then there's the music of Bach playing in the background as she introduces herself, and this funny rule about no textbooks until her students earn them.

And finally, there's the subject she teaches: Latin.

The dead language, right?

Wrong, says Zarndt.

"This language is so powerful and inspiring," she tells her students at Provo High on Friday, their first day. "You will have synapses shooting off in your brain you never had; you will have insights and 'ah-has' you never had."

Long considered stuffy, irrelevant and tedious, Latin is making a comeback. The number of students taking Advanced Placement Latin nationally is nearly double what it was a decade ago, and in Utah, 10 high schools now teach Latin. Two of those schools — Provo High and Vernal's Uintah High — introduced Latin this year.

"Latin is one of those things that fell away in public schools, but now it's coming back," said Roger Macfarlane, a Latin professor at Brigham Young University and a member of the Classical Association for the Middle West and South (CAMWS), an organization that tries to reintroduce Latin to high schools. "The pendulum is swinging back."

At the turn of the century, 44 percent of U.S. students took Latin, largely because it was the official language of the Catholic Church. By 1962, the Vatican had agreed to allow churches to use native languages, and the number of American students studying Latin had dropped to just 7 percent.

Educators say there are two reasons for its resurgence: It seems to help students score higher on tests, and new teaching methods have made the language easier to learn and apply to other subjects.

In 1997, students taking Latin scored a mean of 647 on the Scholastic Aptitude Test verbal exam, compared with the national average of 505, according to the American Council on the Teaching of Foreign Languages.

Jeremy Demmitt, a Provo High senior in Zarndt's class, said he hopes Latin helps him prepare for college and a career as a lawyer.

On his first day in class, Demmitt worked on a Latin crossword puzzle, studied a map of Rome and marveled at the number of English words with Latin roots.

"The real reason Latin is coming back is that the old style of teaching Latin has been pushed aside," said Ginny Lindzey, chair for the CAMWS Committee for the Promotion of Latin. "The old way of teaching grammar the first two years, the emphasis on math and using some intricate code to put sentences together, those days are gone because only the nerds survived.".
