Classical Latin (used by the Romans) didn't have the letters "J", "U", or "W". If you want a quick "Roman" alphabet, use an "uncial" or "half-uncial" font and leave out those letters.

"I" was used as both our vowel "i" and our consonant "j". "V" was used as both our vowel "u" and our consonant "v". Example: "Jesus" = "Iesvs" in Roman. They sound the same.

The "W" wasn't introduced until after 1066, when Norman scribes needed a letter to represent the "whuh" sound present in many early English words.

A lot depends on what date in history or what historical period your teacher is talking about.

Also, the very early Latin script (before the Roman Republic) -- if that's what you need -- isn't something that can be reproduced through fonts available in conventional email. Unlike Greek, which has continued to be used in a relatively unchanged form for thousands of years, the Latin alphabet has undergone stylistic changes unremarked by word processing programs.

We can continue this through my library's email. Look for a reply through there.

And now, back to our regularly-scheduled Space board... (Sorry, guys.)
