History of the Portuguese Language

History of the Portuguese Language
13:58

The Portuguese language belongs to the Romance language family and is one of the most widely spoken languages in the world, with over 300 million native speakers across multiple continents. It is the official language in 10 countries, such as Portugal, Brazil, Angola, Mozambique, and Cape Verde, and plays a crucial role in global communication, trade, and culture. With a history of more than 1,500 years, Portuguese has been shaped by various civilizations, starting from its roots in the Latin language of the Roman Empire to the influences of the Visigoths, Moors, and the Age of Discoveries. Over time, Portuguese has developed through conquests, cultural exchange, and exploration. In this piece, we will delve into the captivating journey of the Portuguese language, tracing its origins as a regional Latin dialect to its current status as a global language, and examining how historical events and regional progress have influenced its evolution. 

The origins: Vulgar Latin in the Iberian Peninsula 

Portuguese has its roots in Vulgar Latin, which was the colloquial form of Latin spoken by the Roman soldiers, merchants, and settlers who arrived in the Iberian Peninsula in 218 BC. Over the next seven centuries of Roman rule, Latin gradually became the primary language in the region, replacing local languages such as Lusitanian, Celtiberian, and Gallaecian. The Romans brought Latin to the Iberian Peninsula following the Second Punic War. They founded numerous colonies and settlements, including Olisipo (modern-day Lisbon) and Bracara Augusta (modern-day Braga). The Latin spoken by the conquerors became more widely used as the Roman Empire expanded and became the official language for administration, law, and culture in the controlled regions. Over time, Vulgar Latin evolved into regional dialects, eventually leading to the emergence of the Romance languages. After the collapse of the Western Roman Empire in the 5th century, Latin experienced a period of decline and fragmentation, giving rise to distinct regional varieties that later developed into Portuguese, Galician, Spanish, and Catalan. 

Pre-Roman influences 

Although Latin formed the foundation of Portuguese, the influence of pre-Roman languages on the western Iberian Peninsula was significant and left a lasting imprint on the language. These pre-Roman languages, spoken by the indigenous populations before the Roman conquest, included Celtic and Lusitanian. While Latin eventually became the dominant language, some words from these ancient tongues survived, enriching the Portuguese vocabulary. For instance, words of Celtic origin, such as "bico" (beak) and "caminho" (path), have been preserved in modern Portuguese. These terms reflect the Celtic influence on daily life and material culture in the region before Romanization. 

The Visigothic era and the Germanic influence 

After the Roman Empire fell in the 5th century, the Visigoths, a Germanic tribe, established their kingdom in the Iberian Peninsula. They adopted the local Vulgar Latin spoken by the Romanized population, incorporating terminology related to warfare, governance, and social structure. These Germanic terms gradually merged into the evolving Latin-based language of the region, contributing to the early development of Portuguese. Notable examples include "guerra" (war), reflecting the martial culture of the Visigoths, and "rico" (rich), denoting authority and aristocracy in the Germanic social hierarchy. 

The Muslim invasion and Arab influence 

In 711 AD, the Iberian Peninsula was invaded by Arab Muslims and Berbers, leading to almost 500 years of Islamic influence in the region that later became Portugal. This era significantly impacted Portuguese's development, affecting its vocabulary, phonetics, and dialects. The substantial Islamic presence introduced numerous Arabic words into Portuguese, especially in areas where the Islamic world excelled.  

For instance, in agriculture, terms such as "açude" (dam) and "alface" (lettuce) were integrated into the language, reflecting the agricultural advancements brought by the Muslims. In the fields of science and mathematics, Arabic contributed words like "algarismo" (digit) and "álgebra" (algebra), while architecture added terms like "alcova" (alcove) and "azulejo" (tile). 

The birth of Portuguese 

The dialect that eventually evolved into modern Portuguese originated in the northwestern region of the Iberian Peninsula, specifically in Galicia and northern Portugal, during the 9th and 10th centuries. This early version of the language, referred to as Galician-Portuguese, was the predominant language of the Christian kingdoms of Galicia and Portugal. 

Several key linguistic developments shaped its evolution: 

  1. Simplification of the Latin declension system 
  1. Development of new verb tenses 
  1. Distinctive phonetic evolution, such as the nasalization of certain vowels 

Early Portuguese literature 

The earliest known writings in Galician-Portuguese date back to the 12th and 13th centuries, a crucial period in developing the Portuguese language and its literature. This era saw the rise of a diverse poetic tradition that laid the foundation for Portuguese literature. The poetry from this time can be categorized into three main types: 

  1. Cantigas de amigo (Friend's Songs): These were poems often written from a young woman's perspective, expressing her longing for her lover or friend. They often featured natural settings and were known for their simplicity and emotional depth. These poems are believed to have originated from ancient folk traditions.
  1. Cantigas de amor (Love Songs): Influenced by the Provençal troubadour tradition, these poems were typically written from a male viewpoint, portraying courtly love and often unreciprocated affection for a noble lady.
  1. Cantigas de escárnio e maldizer (Songs of Mockery and Insult): These were satirical poems that criticized individuals or societal norms. They often contained humor, irony, and, at times, coarse language. These poems were usually set to music and performed by troubadours in royal and noble courts across Galicia and Portugal.

These poems not only mark the beginning of Portuguese literature but also make a significant contribution to medieval European poetry. The Cancioneiro da Ajuda, mentioned earlier, is one of the most important collections of these early poems. Compiled in the late 13th or early 14th century, it contains 310 cantigas de amor. Two other significant compilations are: 

- The Cancioneiro da Vaticana (Vatican Songbook): Contains over 1,200 poems of all three types.  

- The Cancioneiro da Biblioteca Nacional (National Library Songbook): Also known as Colocci-Brancuti, it includes about 1,680 compositions. 

These songbooks are invaluable resources for understanding the early stages of the Portuguese language and its literary traditions. They demonstrate the language's adaptability, expressiveness, and its ability to convey poetic beauty even in its early forms. Notable poets from this period include King Denis of Portugal, Paio Soares de Taveirós (the author of the oldest known cantiga), and Martín Codax, whose work offers a vivid glimpse into medieval Galician-Portuguese culture and society. This early poetic tradition paved the way for the rich literary legacy that would ensue in Portuguese, influencing later works and contributing to the language's prestige and cultural significance. 

King Denis and the promotion of Portuguese 

During his reign, King Denis of Portugal (1261-1325), also known as Dom Dinis in Portuguese, played a significant role in the promotion and recognition of the Portuguese language. His substantial contributions earned him the epithet "The Poet-King" (O Rei Poeta).

  1. Official Language Status: King Denis played a pivotal role in establishing Portuguese as the official language of the royal court and administration. In 1290, he decreed that all official documents should be written in Portuguese rather than Latin. This decision was groundbreaking and had far-reaching implications for the language's development. 
  2. Literary Contributions: As a highly prolific poet, King Denis made notable contributions to the Galician-Portuguese lyrical tradition. He composed over 150 poems, including cantigas de amor, cantigas de amigo, and cantigas de escárnio e maldizer. His works are preserved in the Cancioneiro da Biblioteca Nacional and the Cancioneiro da Vaticana. 
  3. Patronage of the Arts: King Denis was a generous supporter of the arts and education. He established the University of Coimbra in 1290, which is one of the oldest continuously operating universities in Europe. This institution played a key role in the development and standardization of the Portuguese language. 
  4. Cultural Exchange: The king promoted cultural exchange by inviting troubadours and scholars from other parts of Europe to his court. This exchange of ideas and literary styles enriched the evolving Portuguese language and literature. 
  5. Standardization Efforts: Although not a formal standardization, King Denis's use of Portuguese in official documents helped to establish a more consistent written form of the language. This was crucial at a time when regional dialects could differ significantly. 
  6. Translation Projects: King Denis initiated and supported the translation of important works from other languages into Portuguese. This not only enriched the Portuguese vocabulary but also demonstrated the language's ability to convey complex ideas.
  7. Agricultural Treatises: Interestingly, King Denis also authored treatises on agriculture in Portuguese. This aided in developing technical vocabulary in the language and demonstrated its capacity for scientific and practical discourse.


The legacy of King Denis's initiatives laid the groundwork for the Portuguese Renaissance of the 15th and 16th centuries. His promotion of the language contributed to the creation of a distinct Portuguese identity, separate from the broader Iberian culture. King Denis's reign marked a pivotal period in the shift from Galician-Portuguese to what would later become modern Portuguese. His efforts to promote the language in official, literary, and educational spheres were crucial in elevating Portuguese from a regional dialect to a language of administration, literature, and education. This established the foundation for Portuguese to evolve into a global language during the Age of Discoveries in the subsequent centuries. 

The global expansion of Portuguese 

The Portuguese Empire's expansion from the 15th century onwards played a significant role in spreading the Portuguese language globally, reaching regions in Africa, Asia, and South America. This process had several important consequences that shaped the language's evolution and its role in global communication.  

Dialectal diversification: As Portuguese spread to different regions, it evolved into various dialects and regional varieties influenced by factors such as geographical distance, local influences, and interactions with indigenous languages.  

Incorporation of loanwords: The contact between Portuguese explorers and indigenous populations facilitated the incorporation of numerous loanwords from various languages into Portuguese. For example, words like "abacaxi" (pineapple) from Tupi-Guarani and "chá" (tea) from Chinese reflect this linguistic exchange. Portuguese became a global language: The Portuguese Empire's expansion facilitated the rise of Portuguese as a global language. It became essential in diplomacy, trade, and administration, with colonies adopting it as the official language. 

The Lisbon Academy of Sciences 

The Lisbon Academy of Sciences, established in 1779, is a prestigious academic institution in Portugal. It has been instrumental in standardizing and promoting the Portuguese language, by producing authoritative dictionaries and grammars. The Academy also works to preserve and promote Portuguese culture by hosting events and conferences that explore literature, history, and philosophy. Additionally, it has played a significant role in orthographic reforms and has provided recommendations on language policy and education reform. The Academy's influence extends to schools and universities in Portuguese-speaking countries, guiding the teaching and proper use of the language. 

Recent changes 

Portuguese is constantly changing due to cultural, technological, and social developments. Key aspects of this evolution include the incorporation of English words, adaptation to new technologies and social changes, and debates about spelling reforms. The most recent Orthographic Agreement of 1990, implemented in the 21st century, aimed to standardize Portuguese spelling across all Portuguese-speaking countries.
