Portuguese Grammar/Orthography

Portuguese orthography is close to the Latin one, although not so close as French is. Written, it is very similar to Spanish. A text in Portuguese is easy to read, and the reader will have trouble only with the letters x, e and o. However, writing is more complicated and involves etimological rules, i. e., the spelling of some words are defined by Latin. The phoneme s, for instance, can be written in seven ways: s, c, ss, x, ç, sc or sç,

About the letters

c

• c represents the phoneme /s/ before the vowels e (é, ê) and i (í).
• c represents the phoneme /k/ in all other situations.

g

• g represents the phoneme /ʒ/ before the vowels e (é, ê) and i (í).
• g represents the phoneme /k/ in all other situations.

h

As h is never pronouced, it is written by etymological reasons or in digraphs.

In the beginning of the word¹, h are sometimes written in words that also begin in h in Latin:

• haver (to have)
• honra (honor)
• homem (man)
• honesto (honest)
• hora (hour)
• horta (kitchen garden)
• harmonia (harmony)

Contrarely to Italian and French, but similar to Spanish, Portuguese does write the letter h in all the forms of the verb haver (to have / there be): hão, havia, houvera, há.

In the middle of the word, there is never a mute h and it is supressed in compound words, except if hyphen is used:

• habilitar → reabilitar
• harmonia → desarmonia
• higiênico → anti-higiênico

In the end of the word, it is used just in a few number of interjections ²:

• ah!
• oh!
• puh!

m, n

These letters, normally represents the phonemes /m/ and /n/, but, after a vowel, it indicates the nasalisation of the preecedent vowel.

• assunto → /as&u#771to/
• conta → /kõta/
• impar → /ĩpaɾ/
• mentiroso → /mẽtiɾozu/
• sambar → /sãbaɾ/

As sign of nasalisation, we use m before p and b and n in the other cases.

r

r represents two phonemes.

• The r is pronouced strong - /ʁ/ - in the beginning of the word, after a consonant or when it is doubled, in the digraph rr.

• In all other situations, r is pronounced weak, /ɾ/.

s

s is pronouced /z/ between two vowels. In all other situations, it is pronouced /s/.

x

x can be pronouced in five different ways. In the beginning of the word, x is generally pronouced /ʃ/.

• mexer → /meʃer/ (to stir)
• xarope → /ʃaɾopi/ (syrup)
• xeque-mate → /ʃekimati/ (checkmate)

x is pronouced /s/ before a consonant. Before /s/ spelled as c, the letter is soundless.

• exceto → /esɛto/ (except)
• exportar → /espoɾtaɾ/ (to export)
• explodir → /esplodiɾ/ (to explode)
• ex-prefeito → /esprefeɪtu/(ex-mayor)

It is pronouced /ks/ in loan words and between two vowels.

• óxido → /ɔksidu/
• tóxico → /tɔksiku/

Finally, it can be pronounced /z/, between two vowels.

• exato → /ezatu/
• exigência → /eziʒẽsia/

k, w, y

These letters are used only in loan words and international abbreviations:

• byronista
• delivery
• km (quilómetro)
• rock
• skate
• show
• wagneriano
• whiskey

The diacritics

Cedilha

Portuguese, as French and Catalan, uses cedilla (in Portuguese, cedilha) to spell the sound /s/ before the letters a, o, u.

• caçar - /kasaɾ/
• criança - /kriɐ̃sɐ/ (children)
• paço - /pasu

Tonic accent

Note 1: In vocative, the interjection used is ó: Ergue-te, ó Radamés, ó meu vassalo (Luís Delfino).

Note 2: There is only one exception: the interjection ha! or hahaha!
