Very few traces of the native (Lusitanians、Conii、或Calicians) or pre-Roman settlers like the Phoenicians, Carthaginians or Celts lexicon persist in the language, but there are some exceptions, most are unconfirmed.多数葡萄牙地区有古罗马名字，例如是布拉加、科布英拉以及河流Minho和Tamega。

Portuguese, both in morphology and syntax, represents an organic transformation of Latin without the direct intervention of any foreign language.发音、语法及语形，由拉丁语所影响。接近九成的语源是来自罗马。部份受到罗马帝国帝国影响而改变。Since Portuguese was reinfluenced by it (reinfluence represented with 1), many original words are still familiar to Portuguese speakers.
N.B.: 在以下的拉丁语例子，全部使用大阶。下列例子V字以U发音，而C以/k/发音，所以CENTV 发音是 /kentu/ (the derived Cento in Portuguese is pronunced as /se~tu/)。
Nasalization — A vowel before [m] and [n] has a tendency to become a nasal vowel, this occurs in many languages. In the case of Portuguese, it happened between the sixth and seventh centuries. This change sharply distinguishes Portuguese from Spanish, in which it did not occur.
LVNA > l[?]a > Lua (月亮).
Palatalization — Another assimilation occurs before the high vowels [i] and [e], or near the semi-vowel, or palatal [j].
CENTV > [tj]ento > [ts]ento > cento, (hundred)
FACERE > fa[tj]ere > fa[ts]er > fa[dz]er > fazer, (to do)
A more ancient evolution was FORTIA > for[ts]a > forca (strength)
Elision — Simultaneous influence in a consonant by vowels, occurring a sintagmatic chain.
DOLORE > door > dor (pain) — dolorido1 (in pain)
BONV > boo > bom, (good)
ANELLV > aelo > elo (Ring) — Anel1 (hand ring)
Voicing — some consonants did not disappear but rather evolved:
MUTV > mudo (deaf)
LACV > lago (lake)
FABA > fava (broadbean)
Simplification of consonant clusters, especially doubled vowels, occurred:
GVTTA > gota (drop)
PECCARE > pecar (to sin)
Dissimilation — Modification of a sound by the influence of neighbouring sounds.
Dissimilation between vowels:
LOCVSTA > lagosta (lobster)
CAMPANA > campaa > campa (tomb)
Dissimilation between consonants:
MEMORARE > nembrar > lembrar (to remember) — Memorizar1 (to memorize)
ANIMA > alma (soul) — Animado1 (livened up)
LOCALE > logar > lugar (place) — local1 (place)
Some other alterations were semi-vowel metathesis: PRIMARIV becomes primeiro (Eng. first); consonant metathesis in [l] and [r] are rare in Portuguese (e.g. TENEBRAS > teevras > trevas, Eng. darkness); and epenthesis, where there is not a total assimilation by adding new sounds. Such as for wine: Vulgar Latin: VINO, medieval Portuguese Vi~o, Modern Portuguese (since 14th or 15th centuries): Vinho. However, the sound of medieval Portuguese is still alive in some Portuguese dialects of Brazil and Sao Tome and Principe. Another specially relevant shift was the loss of the intervocalic /l/ in a very large set of words, already described in the list above as an example of "elision" → e.g: SALIRE > sair; COLARE > coar; NOTVLA > nodoa, with the typical portuguese voicing of /t/ in /d/ (AMATVS > amado). Fewer words remaned unchanged, such as Taberna (tavern).

葡萄牙语使用26个拉丁字母。当中K、W及Y只适用于非葡萄牙语原创词语如darwinismo (达尔文主义）. It uses c and acute, grave, circumflex and tilde accents over vowels, as well as, in some forms and only in Brazil, diaeresis on a U as in linguistica (语言学，其余葡语圈人士使用linguistica）。

在巴西，第一个"c" 是"cc"、"cc"或"ct"及"p"如"pc"、 "pc" 或 "pt" 是葡语言未能发音而培养戈成能够说话，是由拉丁语遗留下来。
发音不同。Brazil in words such as "Antonio" (Anthony) or "anonimo" (anonimous) uses close vowels, where Portugal and Africa uses open ones, "Antonio" or "anonimo", respectively. In the case of Africa, it is mostly due that the European Portuguese is preferred standard.
A Spelling Reform (Port. Reforma Ortografica), written in 1990, will create an International Portuguese Standard, and it was ratified by Brazil, Cape Verde and Portugal. East Timor, not an original subscriber, will ratify shortly along with Guinea-Bissau. East Timor was the biggest supporter for a fast implementation and pressured CPLP. The agreement's Implementation date is not yet set.
At first, the Agreement established that its entrance into practice would only occur when all the countries of the CPLP had ratified it. But the African countries of Portuguese language have not ratified, possibly due to problems in implementing it. In the CPLP’s summit of 26–27 July 2004, an adjustment will prompt implementation in Brazil, Cape Verde and Portugal and its use can also be done in the other countries. The agreement will eliminate most "c" when "cc", "cc" or "ct"; and "p" when "pc", "pc" or "pt" from European Portuguese, the dieresis and accent marks in words ending in "eia" in Brazil and added some new minor spelling rules. And will accept dual accentuation in words like anonimo or anonimo, now depending on a person's accent.
