Briefly, vulgar (common) Latin was used throughout the Roman Empire.
Vulgar Latin.
The Romans were Latins and therefore spoke Latin. There were two forms of the language, Vulgar Latin and Classical Latin. Vulgar Latin or sermo vulgaris (common speech) was the colloquial Latin spoken by the people. Classical Latin was the formal Latin which evolved in the classical period with the development of the written language. It was used in literature, academic work and administration and was spoken by the educated elites. Vulgar Latin was an informal tongue. It was not standardised and was not put in writing and, therefore, had no orthography. Very little is known about this form of Latin. Over time and with the expansion of the Roman Empire it became more like a collection of local dialects which were influenced by the languages of the local non-Roman peoples. The Vulgar Latin spoken in Gaul was not the same at that spoken in Hispania, Dalmatia, Rome, etc.The language spoken by the ancient Romans was Latin.
Latin was spoken by the ancient Romans from around the 5th century BC. It gradually evolved into Vulgar Latin and then into the Romance languages spoken in different regions of the Roman Empire as it expanded.
Two languages that evolved from Latin are Italian and Spanish. These languages developed from Vulgar Latin, the colloquial form of the Latin language spoken by common people.
Spanish evolved from Vulgar Latin, which was the spoken language of the Roman Empire. Over time, Vulgar Latin developed into different Romance languages, with Spanish being one of them.
Spanish originated from Vulgar Latin, which was a form of Latin spoken by common people in the Roman Empire. Over time, Vulgar Latin evolved into the various Romance languages, including Spanish.
Spanish, also known as Castilian, developed from Vulgar Latin, the popular form of Latin spoken by the common people in the Iberian Peninsula during the Roman Empire. As the centuries went by, Vulgar Latin underwent various changes and evolved into what is now known as Spanish.
Spanish and Portuguese are Romance languages, which evolved from Vulgar Latin, the spoken language of the Roman Empire.
Latin originated in Latium, a region in Italy, and it was the language spoken by the ancient Romans. It later evolved into different forms such as Classical Latin (used in literature and formal writing) and Vulgar Latin (used in everyday speech).
The people of Herculaneum spoke a form of Latin known as Vulgar Latin, which was the common spoken language of the Roman Empire.
French language formed in France, from the vulgar Latin languages spoken there at the end of the Roman era.
Romance languages, such as Spanish, French, Italian, Portuguese, and Romanian, originated from Vulgar Latin, the colloquial form of Latin spoken by the common people of the Roman Empire. As the Roman Empire declined, Vulgar Latin evolved into different regional dialects, which eventually developed into distinct Romance languages. These languages were influenced by the languages spoken by the indigenous populations in different regions.
