How do you say beautiful art in Latin?

Arte is an Italian equivalent of the English Word "art."

Specifically, the Italian Word is a feminine noun. Its singular definite article l'* means "the." The pronunciation is "AHR-teh."

*It actually is la. But the vowel a drops before a noun that begins with the same vowel. It is replaced by an apostrophe immediately after the remaining letter l in the article and immediately before the first letter in the following noun.
