In 1990, several Portuguese-speaking countries agreed on a spelling reform to create and maintain a cohesive, international standard across borders.

In Portugal, the spelling reform was enacted in 2009 followed by a 6-year transitional period where the old and new orthographies were officially co-existing. To this date, however, there’s a de facto spelling double standard in Portugal.

This double standard is partly due to a widespread lack of awareness of the new spelling rules and partly the fact that several journalists, authors, and a few publishers refuse to follow the new orthography (for reasons outside the scope of this article).

Seeing the same word spelled differently in different sources must be confusing for language learners (for instance, baptismo vs. batismo). Among other things, I’d like to clarify which spellings agree with the spelling reform*. Read on.

* The spelling reform pertains exclusively to orthography, that is, it doesn’t have anything to do with phonology or lexicon. Brazilians, Portuguese, Angolans, and other native Portuguese speakers keep pronouncing the words as before as they keep using their local, culture-specific words and expressions.

Silent consonants

Except for the letter h – which in Portuguese is always mute – we no longer write mute consonants such as silent c’s or p’s.

Here’re a few examples:

Before	After
acto	ato
acção	ação
detective	detetive
óptimo	ótimo
baptismo	batismo
. . .

But! We keep the c’s and p’s when we pronounce them:

Before	After
facto	‘’
pacto	‘’
Egípcio	‘’
. . .

! A common misunderstanding

I often hear people talking against the spelling reform (and refusing to follow it) based on a widespread misunderstanding: they think that all those p’s and c’s mentioned above are – according to the reform –  gone, even when you are supposed to pronounce them, which is not true as illustrated by the table above. 

There are a few words subjected to alternative spellings. Those are cases where some pronounce the c’s and the p’s while others don’t. Then, either spelling is considered correct:

Before	After
infeccioso	‘’ or infecioso
sectorial	‘’ or setorial
olfacto	‘’ or olfato
. . .

Last but not least, in some words, these c’s and p’s are pronounced in the European standard but not in Brazilian. And vice-versa. 

In these cases, there is a double standard according to each variant of Portuguese:

European standard	Brazilian standard
facto	fato
contactar	contatar
defetivo	defectivo
conceção	concepção
corrupção	corrução
receção	recepção
. . .

Diacritical marks

To accommodate differences in pronunciation between the European and Brazilian standards, some words are subject to different accent marks:

European Portuguese	Brazilian Portuguese
académico	acadêmico
cénico	cênico
bidé	bidê
. . .

The circumflex accent marks a more closed vowel sound. Learn more about Portuguese diacritics here: Portuguese Word Stress and Accent Marks

Before the reform, the 1-person plural in the preterite tense (Pretérito Perfeito) took an accent mark to graphically distinguish it from the present tense (same pronunciation and spelling otherwise)*.

After the reform, it became optional to use the accent mark:

Before	After
Ontem ficámos em casa Hoje ficamos em casa	Ontem ficámos/ficamos em casa Hoje ficamos em casa
Ontem cozinhámos bacalhau Hoje cozinhamos bacalhau	Ontem cozinhámos/cozinhamos bacalhau Hoje cozinhamos bacalhau
. . .

* Only applies to regular verbs of the -ar conjugation group.

Before the reform, a few verbs of the second and third conjugation groups (-er, -ir) had a circumflex accent mark on the 3-person plural. That’s not the case any longer:

Before	After
crêem (crer)	creem
vêem (ver)	veem
lêem (ler)	leem
. . .

Before the spelling reform, the verb form para (verb Parar)  had an acute accent mark to denote a more open vowel sound compared to the preposition para. 

These days, the verb form and preposition are homographs (same spelling, different pronunciation):

Before	After
pára (verb from)	para (verb from)
para (preposition)	‘’

The diphthong oi no longer takes an accent mark (to denote an open vowel sound) unless it comprises the last syllable:

Before	After
asteróide	asteroide
jóia	joia
but
herói	‘’
constrói	‘’
. . .

Hyphenation

The hyphen drops

We no longer use a hyphen in compound words with prefixes such as anti-, re-,  co-, extra-, intra-, pro-, multi-, pluri-, contra-, among others:

Before	After
co-dependente	codependente
re-equilíbrio	reequilíbrio
contra-indicação	contraindicação
neo-impressionismo	neoimpresionismo
auto-avaliação	autoavaliação
geo-estratégico	geoestratégico
multi-color	multicolor
pluri-anual	plurianual
. . .

Also, we don’t use the hyphen in compound words where the first part ends in a vowel and the remainder starts with r or s. 

However, we do have to duplicate the s and r so that the spelling agrees with Portuguese spelling-pronunciation patterns*. 

Before	After
contra-regra	contrarregra
anti-semita	antissemita
auto-rádio	autorrádio
. . .

We don’t hyphenate compound words with the prefix mal- unless the suffix starts with a vowel or h :

Before	After
mal-falante	malfalante
mal-criado	malcriado
but
mal-amado	‘’
mal-estar	‘’
mal-humorado	‘’
. . .

We no longer use a hyphen between Haver’s verb forms and de:

Before	After
hei-de ir ao Japão	hei de ir ao Japão
hás-de me entender	hás de me entender
. . .

The hyphen is kept

We hyphenate compound words to be consistent with Portuguese spelling-pronunciation patterns.

Except for prefixes re– and co-, we hyphenate compound nouns in which the prefix ends in a vowel and the suffix starts with the same vowel:

Before	After
contra–ataque	‘’
micro–ondas	‘’
auto–observação	‘’
. . . but
co–operação	cooperação
co–ordenação	coordenação
re–escrever	reescrever
. . .

Also, we use the hyphen in compound words with prefixes ending with an –r – such as hiper-, inter-, or super- – and suffixes starting with the same letter:

Before	After
hiper–resistente	‘’
super–reacionário	‘’
. . .

We hyphenate compound words denoting plants and animals:

Before	After
couve-flor	‘’
erva-doce	‘’
bicho-da-seda	‘’
. . .

We hyphenate compound words with prefixes ending in –m (nasal sound) such as bem-, além-, aquém-, and recém- 

Before	After
bem-vindo	‘’
além-mar	‘’
recém-nascido	‘’
sem-abrigo	‘’
. . .

We hyphenate compound words that take the prefixes ex-, vice-, pré-, pós- och pró-:

Before	After
ex-marido	‘’
vice-presidente	‘’
pré-história	‘’
pró-democracia	‘’
pós-parto	‘’
. . .

Lower- or uppercase?

According to the spelling reform, weekdays, months, and seasons are no longer capitalized:

Before	After
Terça-feira	terça-feira
Março	março
Primavera	primavera
. . .

Concerning titles and headings, only the first word is capitalized:

Before	After
O Crime do Padre Amaro	O crime do padre Amaro
Crime e Castigo	Crime e castigo
E Tudo o Vento Levou	E tudo o vento levou
. . .

Moreover, forms of address are no longer capitalized:

Before	After
Senhor Doutor Sr. Dr.	senhor doutor sr. dr.
Senhora Engenheira  Sra. Eng.	senhora engenheira  sra. eng.
Excelentíssimo  Senhor Exmo. Sr.	excelentíssimo senhor exmo. sr.
. . .

You get to choose whether or not you capitalize religious scriptures, saints and other sacred figures, subjects of knowledge, monuments, streets, and public places:

Before	After
Nossa Senhora	‘’ or nossa senhora
Bíblia	‘’ or bíblia
Igreja da Misericórdia	‘’ or igreja da misericórdia
Matemática	‘’ or matemática
Avenida da Liberdade	‘’ or avenida da liberdade
. . .
