Use the adjective latinate to describe languages, words, or phrases that are derived from Latin.
Languages that descended directly from Latin, like Spanish, French, and Italian, are latinate. Although English is not one of these latinate languages, many English words, from auxiliary to vulnerable have a latinate derivation. You might also use fake words that only resemble Latin, with the latinate filler text known as "Lorem Ipsum" that's used to design a layout where future information will be printed.
