Latin is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets. Latin was originally spoken in Latium, Italy. Through the power of the Roman Republic, it became the dominant language, initially in Italy and subsequently throughout the Roman Empire. Vulgar Latin developed into the Romance languages, such as French, Italian, Portuguese, Spanish, and Romanian. Latin and French have contributed many words to English. Latin and Greek roots are used in theology, biology, and medicine.
