A unique developmental pattern of Portuguese language has to do with the evolution of Portugal Portuguese as opposed to Brazilian Portuguese. The number and type of loan words as well as some grammatical and pronunciation aspects may differ with Brazilian Portuguese having more influences from Native American languages that existed in Brazil, as well as the different immigration patterns of each of the countries. Most notably, there is a large ethnic Japanese community in Brazil and some Japanese loan words have entered Brazilian Portuguese.
Portuguese grammar and writing is also unique compared to other Romance languages. Linguists consider Portuguese to have preserved the most verbal inflections from Latin compared to any of the other languages. The writing system itself employs the Latin script of 26 letters. However, it has five diacritics, or ‘accent marks,’ to denote various aspects of pronunciation, that other Romance languages may not denote. For example, stress, vowel height (the ‘note of the vowel’), contractions of multiple vowels, nasalization of vowels, and many other sound changes are all represented. To people not familiar with Portuguese, it may seem that there can be many accent marks in just one word.
Like other Romance languages, Portuguese is written from left to right and from the top of the page to the bottom of the page. Also, punctuation is largely similar to the systems found in Romance languages as well, even though there may be some differences in both punctuation and spelling between Brazilian and European Portuguese. Interestingly, an international treaty called the Portuguese Language Orthographic Agreement of 1990, which has most recently been updated in 2016, was created so that there was a unified spelling system for all countries who have Portuguese as an official language, even though in the case where two forms of spelling existed in Brazil and Portugal, both forms still remain.
Historically, the earliest documentation of texts in Portuguese come from the 9th century and from the region of the County of Portugal. At this time, Galician-Portuguese was considered one language and was spoken in this region. Galician-Portuguese dialects were the colloquial varieties that broke off from Vulgar Latin in this particular region. However, as time went on, there was a separation of Galician-Portuguese into two distinct languages, especially with the founding of the Portugal Kingdom in 1143 and the split of the County of Portugal from Galicia. Scholars consider this the start of Old Portuguese as well as the beginning of the development of Portuguese as a distinct language.
The Renaissance in the 16th century can be considered the start of Modern Portuguese. In the beginning of this time period, the interest in humanistic philosophy and academics led to a heavy borrowing of loan words from both Latin and Ancient Greek into Portuguese. More importantly, the printing press helped with the standardization of Portuguese as it allowed publications to reach the masses. With the masses mostly understanding Portuguese, the language of publication was decided to be the Portuguese spoken at this time.
During the Age of Discovery, modern Portuguese continued to develop. During this time, Portugal colonial ambitions, religious missionaries, traders, and explorers brought the Portuguese language, culture, and people, into contact with many influences around the world. Such contact, in turn, affected the language development of Portuguese with loanwords coming from Japanese, Malay, Indonesian, and more.
Currently, Portuguese is a major world language. It is an official language of the European Union, Mercosul (a South American trade bloc), the African Union, and many other international organizations. It is the official language in nine countries, and a recognized language in 14 others. Portuguese also has cultural significance ranging from music (e.g. Brazilian Bossa Nova) to martial arts (e.g., Capoeira, also having roots in Brazil). In summary, Portuguese language and Portuguese translation will continue to play a role in international affairs and culture for years to come.
