* Rediscovery of Classical Languages: The Renaissance saw a renewed interest in the classical languages of Latin and Greek. Scholars studied ancient texts, which led to a revival of these languages and their influence on modern European languages. This led to greater sophistication and complexity in writing and speech.
* The Rise of Vernacular Languages: Alongside the rediscovery of classical languages, vernacular languages (languages spoken by everyday people) gained new prominence. This was partly due to the invention of the printing press, which made it easier to produce books in the vernacular. Writers like Dante, Chaucer, and Cervantes used their native languages to create powerful works of literature, contributing to the standardization and development of these languages.
* Expansion of Vocabulary: The rediscovery of classical texts, exploration, and scientific discoveries led to the introduction of new words and concepts. This contributed to the expansion and refinement of existing languages.
* Development of New Literary Forms: The Renaissance saw the emergence of new literary forms, such as the sonnet, the play, and the novel. These forms required new language skills and helped to shape the evolution of languages.
* Increased Literacy: The printing press and other factors led to increased literacy rates, which further promoted the use and development of languages.
Therefore, the Renaissance wasn't about language "increasing" in a quantitative sense, but rather about a significant transformation and growth in the use, development, and sophistication of languages. It was a period of exciting linguistic change that laid the groundwork for the languages we speak today.
