Latin language
Latin (lingua latina) was an ancient Human language spoken by the Romans in antiquity. It was also the official language of the Romans. With time Latin evolved to many other languages, such as Italian, Spanish, and French. More than half of the vocabulary of the English language had its origin from French and Latin, and the language was used long after extinction for certain ceremonial purposes, such as mottoes, and the names of certain star systems and planets.

Species native to Earth were given both a Latin name and a common name. (; )

Many Earth proverbs were in Latin and were often used as mottos of starships or installations. A course based on this language was taught at Starfleet Academy. ()

When Wesley Crusher was on leave from Starfleet Academy, Captain Jean-Luc Picard checked on his Latin by asking him:

"Quomodo tua Latinitas est?" ([ˈkʷoːmɔdɔ ˈtuːa laˈtiːnɪtas ɛst]; "How is your Latin?")

Wesley responded:

"Praestat quam prius." ([ˈprajstat kʷam ˈpriːʊs]; "It's better than before.")

whereupon the Captain responded:

"Oppido bonum." ([ˈɔpɪdɔ ˈboːnʊm]; "Very good.") ()

When counseling a de-aged Picard about his options, Deanna Troi suggested he go back to Starfleet Academy and brush up on his Latin, a suggestion he balked at. ()

The term arboretum is derived from the Latin word for tree, arbor ([ˈarbɔr]). This connection was noted by the Cairn Hedril in 2370. ()

Q remembered Vash was called persona non grata ([pɛrˈsoːna nɔn ˈgraːta]), meaning "an unwelcome person", on Betazed. ()

According to the Exarch Hadran of the Nehelik Province on the planet Rakhar, Croden was declared guilty in absentia (meaning, "in the absence") for crimes against his world. ()

The holographic Henry Burleigh advised his governess Lucille Davenport, played by Captain Kathryn Janeway: "In ullam rem ne properemus" ([ɪn ʊllam rɛm nɛ prɔpɛˈr eː mʊs]; "Let's not rush into anything"), and asked her whether her Latin was a little rusty when the Captain didn't understand his remark. Janeway admitted that her Latin was indeed a little rusty. () 

The holographic Seamus attempted to exorcise the spirit folk (actually the crew of ) in 2376 by saying, "Ex labis caelestium sanctorum super ad aures atrorum larvarum mentientium." He followed up by translating the phrase: "From the lips of the heavenly saints above, to the ears of the dark and lying spirits". ()

D'Vana Tendi spoke in Latin, stating "utique, saeculorum lapsu…" (meaning "of course, the fall of the ages") as she followed  O'Connor around attempting to assist him with his spiritual ascension. ()

In 3190, Dr. Kovich assured Captain Michael Burnham "experto credite" ("trust the expert") in attempting to understand Zora's new found sentience. ()
