Why Are the Romance Languages All So Similar?

The Romance languages are notably similar due to their relatively recent divergence from Latin, which was extensively unified by the Roman Empire and subsequently preserved by the Catholic Church.

• Romance languages are similar due to a common Latin origin, reinforced by the Roman Empire's widespread linguistic unification.

• The collapse of the Western Roman Empire led to the divergence of vernacular Latin into distinct Romance languages across different regions.

• Classical Latin persisted as a formal language through the Catholic Church, influencing the ongoing development and conservatism of some Romance languages.

While the similarity of Romance languages is often attributed to Latin, it's also due to the Roman Empire's forceful suppression of other Italic languages and its cohesive influence across the peninsula. Post-Roman Empire, Latin's vernacular dialects diverged into distinct Romance languages, yet Classical Latin persisted as a formal language through the Catholic Church. This dual evolution, coupled with a more recent common ancestor compared to other language families, explains their strong resemblances.

Ancient Italic Languages

• 00:00:40 Before Rome's expansion, Latin was confined to Latium, with the rest of the Italian Peninsula dominated by other Italic languages like Osco-Umbrian, Venetic, and Siculian. Non-Italic languages such as Etruscan and Greek were also prominent, with Greek influencing the development of the Old Italic and eventually Latin alphabets. By the 1st century BC, Roman expansion and a civil conflict known as the Social War led to the extinction of these other Italic languages, solidifying Latin's dominance.

Divergence of Latin Dialects

• 00:03:48 The vast Roman Empire led to numerous Latin accents and dialects, sometimes referred to as 'Vulgar Latin,' which was a casual register rather than a distinct social dialect. Roman authors documented this 'sermo vulgaris,' noting differences in pronunciation and loanwords. Following the collapse of the Western Roman Empire and the absence of a unifying authority, these common vernaculars diverged into distinct Romance language branches, including Western, Pannonian, Eastern, Southern (Island), and African Romance, with geographical isolation further accelerating this process.

Formation of New Languages

• 00:06:04 The transition from a Latin dialect to a new Romance language was gradual, with each generation adopting subtle linguistic changes that accumulated over time. The earliest written records distinguishing new Romance languages from Latin, like the Oaths of Strasbourg in 842, demonstrate this divergence. In the Iberian Peninsula, the Visigothic and later Umayyad rules influenced local Romance dialects, leading to unique languages like Mozarabic and Ladino, while in Italy, various regional languages evolved independently of Tuscan, which later became standard Italian.

Latin's Enduring Legacy

• 00:10:22 Unlike other Proto-languages, Latin continued to be spoken, albeit as a learned language rather than a native one, long after its vernacular forms diverged. It served as Europe's primary inter-cultural lingua franca for politics, science, and religion, especially through the Catholic Church, which cemented its use among elites. This persistent formal use explains why Classical Latin and Ecclesiastical Latin maintained distinct pronunciations and why some Romance languages, like Sardinian, are considered 'conservative' due to preserving older Latin phonetic features.
