Latin, an Indo-European language, is often considered 'dead'. Classical Latin, the language of Mark Antony and Caesar, is no longer an official language outside Vatican City. However, Vulgar Latin, most used throughout the Roman Empire's zone of influence, gradually evolved into many of today's languages (i.e., Romance: French, Italian, Spanish, Portuguese, Romanian).
Embedded alongside modern communication, it risks obscuring the already obscure. Akin to Easter eggs, I recently delved into many contemporary uses of Latin to enrich my understanding.
Interesting aside: Modern English is considered the world's lingua franca, a communication bridge. A West Germanic language, English emerged from the Angles, Saxons, and Jutes peoples. In constant change, it is influenced by Latin, French, and Dutch.
