Augmentatives are the conceptual opposite of diminutives — suffixes that make a noun bigger, stronger, more intense, or more extreme. They are less systematic than diminutives, with several competing suffixes (-ão/-ona, -aço/-aça, -arrão, -alhão) that carry different shades of meaning, and they are more pragmatically loaded: an augmentative can praise (golaço = "great goal") or insult (narigão = "big nose, unattractive"), and the line between the two often depends on the specific noun, tone, and context. Augmentatives are also distinctively informal — you will hear vinhaço in conversation about wine, but almost never read it in a restaurant menu. This page covers the major suffixes and their uses, and flags the situations where an augmentative will come across very differently from what a learner intends.
The main augmentative suffixes
Portuguese has several competing augmentative suffixes. The most productive is -ão/-ona, but -aço/-aça is close behind, and a handful of others appear in specific contexts.
-ão/-ona — the default augmentative
This is the primary augmentative suffix. Masculine nouns take -ão; feminine nouns take -ona. The suffix drops the final vowel of the base (if there is one) and attaches directly.
Ele é um grandão e joga basquetebol desde os dez anos.
He's a big guy and has been playing basketball since he was ten.
Recebeu um abração do avô quando chegou ao aeroporto.
He got a big hug from his grandfather when he arrived at the airport.
A minha tia é uma mulherona que não se cala nem um minuto.
My aunt is a big strong woman who doesn't shut up for a minute.
Examples: homem → homenzão or homenzarrão (big man), mulher → mulherona (big strong woman), beijo → beijão (big kiss), abraço → abração (big hug), livro → livrão (big book).
-aço/-aça — quality and enthusiasm
The -aço suffix specifically emphasises quality — something outstanding, impressive, or extreme in its kind. It is much more evaluative than the plain -ão.
Que golaço! Aquele remate foi do outro mundo.
What a great goal! That shot was out of this world.
O jantar estava uma maravilha — um vinhaço e um bacalhau divinal.
Dinner was wonderful — an amazing wine and a divine cod dish.
Vimos um filmaço ontem à noite — recomendo vivamente.
We saw a great film last night — I strongly recommend it.
Examples: golo → golaço (great goal), vinho → vinhaço (great, strong wine), filme → filmaço (great film), jogador → jogadoraço (great player), ano → anaço (great year). For carro, the standard augmentative is carrão — carraço is heard but is non-standard.
-arrão/-arrona — intensified augmentative
This is an augmented augmentative — a compound suffix that stacks intensity. It's more colloquial and carries more force than plain -ão.
O vizinho do lado é um homenzarrão de dois metros de altura.
The next-door neighbour is a huge man two metres tall.
Vivem numa casarrona com piscina e jardim enorme.
They live in a huge house with a pool and a massive garden.
Examples: homem → homenzarrão (hefty man), casa → casarrona or casarão (big house), rapaz → rapagão or rapazarrão (big lad).
-alhão/-alhona — pejorative augmentative
This suffix carries a strongly negative or pejorative connotation — scorn, disparagement, ridicule. It is not neutral.
Aquele vagabundalhão nunca trabalhou um dia na vida.
That good-for-nothing has never worked a day in his life.
Não sejas parvalhão — a aranha é tão pequena.
Don't be a total idiot — the spider is so small.
Because this suffix is pejorative, most -alhão words are insults or near-insults. Use with caution, or not at all until you know the register well.
The semantic uses of augmentatives
Augmentatives are not just about physical size. Like diminutives, they carry a range of pragmatic meanings that learners have to sort out by context and tone.
1. Literal largeness
The most straightforward use: something is physically big.
O narigão dele é uma característica de família.
His big nose is a family trait.
Vivem num apartamentão no centro de Lisboa.
They live in a huge apartment in the centre of Lisbon.
Aquele cão é um cachorrão — deve pesar quarenta quilos.
That dog is a huge hound — it must weigh forty kilos.
2. Affection (especially with people and greetings)
This is perhaps counterintuitive: despite their aggressive sound, some augmentatives are affectionate rather than hostile. Um abração and um beijão are standard friendly sign-offs in speech, letters, and messages.
Um abração para ti e para a família — sentimos a tua falta.
A big hug to you and the family — we miss you.
Beijões e até à próxima!
Big kisses and see you soon!
O meu filhão já tem quinze anos e é mais alto que eu.
My big boy is already fifteen and taller than me.
3. Quality and enthusiasm
The -aço form especially signals that the speaker is impressed. This is the "what a great X!" sense.
Que golaço, pá! Foi o melhor da época toda.
What a great goal, mate! It was the best of the whole season.
Que jantaraço! Obrigada pela recomendação.
What a fantastic dinner! Thanks for the recommendation.
Tens um carrão novo? Mostra lá.
Have you got a great new car? Come on, show me.
4. Pejorative — size as criticism
When directed at body parts or physical traits, augmentatives often become insults. Narigão (big nose), boção (big-mouthed, someone who talks too much or is tactless), orelhão (big ears). For a stubborn or pig-headed person, cabeçudo is the default word in PT-PT, though cabeção is heard colloquially.
Cala-te, boção! Ninguém te perguntou nada.
Shut up, bigmouth! Nobody asked you anything.
Ele é um teimosão — nunca admite que está errado.
He's really stubborn — he never admits he's wrong.
5. Intensity (non-size)
Augmentatives can intensify qualities that have no physical size at all.
Está um friaço lá fora — leva casaco.
It's bitterly cold outside — take a coat.
Passei um calorão na praia ontem — nem consegui dormir.
I was roasting at the beach yesterday — I couldn't even sleep.
Levei um sustão quando o carro ao lado travou a fundo.
I got a big scare when the car next to me slammed on the brakes.
6. Solteirão / solteirona — social-role augmentatives
Some specific augmentative forms have settled into fixed social descriptions, usually with a slightly archaic or judgmental feel.
Ficou solteirão — nunca quis casar, e agora tem sessenta anos.
He stayed a confirmed bachelor — never wanted to marry, and now he's sixty.
The feminine solteirona ("old maid, spinster") is more strongly negative and increasingly avoided. Solteirão for a man is mildly humorous-to-judgmental depending on context.
The gender rule: -ão is always morphologically masculine
One of the oddest features of -ão as a suffix is that the resulting noun is grammatically masculine, regardless of the gender of the base. If you want a feminine version, you need -ona (or a different suffix altogether).
| Masculine base | Augmentative | Gender of augmentative |
|---|---|---|
| homem (m.) | homenzão | masculine |
| filho (m.) | filhão | masculine |
| beijo (m.) | beijão | masculine |
| mulher (f.) | mulherona | feminine |
| casa (f.) | casarão | masculine! — shift of gender |
| porta (f.) | portão | masculine (and specialised meaning: gate) |
| chapa (f.) | chapão | masculine |
A casa velha tornou-se um casarão abandonado no centro da vila.
The old house became an abandoned mansion in the centre of the village.
O portão do jardim está aberto — alguém entrou.
The garden gate is open — someone has come in.
Augmentatives with diminutives
Portuguese allows layered derivation — you can put a diminutive on an augmentative or vice versa, creating subtle tonal shades.
O miúdo marcou um golaçozinho — pequenino, mas bem bonito.
The kid scored a cute little great goal — small, but really pretty.
These stacked derivations are highly colloquial and humorous. They're not standard in writing.
Plurals of augmentatives
Augmentatives follow the same plural rules as other nouns ending in -ão — a topic complicated enough to have its own page. For augmentatives specifically, the plural is usually -ões.
Os abraços e os beijões que recebi no casamento foram inesquecíveis.
The hugs and big kisses I got at the wedding were unforgettable.
Os rapazões do bairro jogam futebol todas as tardes.
The big lads from the neighbourhood play football every afternoon.
abração → abrações, beijão → beijões, golaço → golaços, mulherona → mulheronas.
Register: augmentatives are distinctively informal
Augmentatives are among the most clearly informal morphological features of Portuguese. They do not appear in formal writing — news articles, official documents, academic prose. They are at home in:
- Conversation — especially among friends, family, and in football/sports commentary.
- Text messages — Um abração, até amanhã!
- Informal writing — blog posts, personal emails, social media.
- Sports and entertainment journalism — where golaço and filmaço are near-technical terms.
In a formal report, you would write um grande abraço or um abraço sincero instead of um abração, uma vitória excecional instead of uma vitoriona, um excelente filme instead of um filmaço.
Comparison with diminutives
| Feature | Diminutives | Augmentatives |
|---|---|---|
| Primary suffixes | -inho/-inha, -zinho/-zinha | -ão/-ona, -aço/-aça |
| Productivity | extremely high (almost any noun) | high but patchier |
| Default tone | affectionate, polite, warm | emphatic, sometimes rough |
| Can be ironic | yes | yes (que jeitão) |
| Formal register | rare | very rare |
| Gender behaviour | matches base (livro → livrinho, m.; casa → casinha, f.) | -ão is always masculine (casa → casarão, m.!); feminine requires -ona |
| Stacking | common (pequenininho) | less common but possible |
How this differs from English
English augmentatives are mostly analytic rather than morphological — you say "huge X," "a great X," "a big X." There is no English suffix that corresponds productively to -ão or -aço. The closest equivalents are:
- -aço ≈ "great X" / "what a X!" — golaço ≈ "what a goal!"
- -ão (affectionate) ≈ "big" in a warm sense — abração ≈ "big hug"
- -ão (pejorative) ≈ "big" with insult force — narigão ≈ "big honker nose"
English speakers learning Portuguese tend to under-use augmentatives because there's no morphological habit to transfer. Adding a handful of common ones to your active vocabulary — um abração, um beijão, que golaço, um bocadão, um calorão — will make your Portuguese sound much more native.
Common mistakes
❌ A casarona no fim da rua está à venda.
Incorrect — casa is feminine, but casarão is masculine (the -ão suffix imposes masculine gender). The feminine form casarona exists but is rare and non-standard.
✅ O casarão no fim da rua está à venda.
The big house at the end of the street is for sale.
❌ Que bom golão marcou o Ronaldo!
Incorrect register — for a goal, the quality-augmentative -aço is correct. Golão is not a standard word for 'great goal'.
✅ Que golaço marcou o Ronaldo!
What a great goal Ronaldo scored!
❌ O relatório anual incluiu um grandão sucesso para a empresa.
Incorrect register — augmentatives don't belong in formal business writing.
✅ O relatório anual incluiu um grande sucesso para a empresa.
The annual report included a major success for the company.
❌ A minha tia é um mulherão que não se cala.
Incorrect in PT-PT — mulher is feminine, so the augmentative is mulherona, agreeing in gender.
✅ A minha tia é uma mulherona que não se cala.
My aunt is a big strong woman who never shuts up.
❌ A minha tia é uma solteirão de cinquenta anos.
Incorrect — the feminine form of solteirão is solteirona.
✅ A minha tia é uma solteirona de cinquenta anos.
My aunt is a fifty-year-old spinster.
Key takeaways
- The main augmentative suffix is -ão (masculine) / -ona (feminine); the suffix attaches to the base with the final vowel dropped.
- The -aço/-aça suffix specifically marks quality — golaço, filmaço, vinhaço — and is almost always positive.
- -arrão intensifies further (homenzarrão), and -alhão is strongly pejorative (vagabundalhão).
- Augmentatives express largeness, intensity, affection, quality, or insult — context and tone tell you which.
- -ão forms are always grammatically masculine, even when formed from feminine bases (casa → casarão, masculine!). Feminine augmentatives use -ona or a different suffix.
- Augmentatives are distinctively informal — appropriate in conversation, messages, and sports commentary, but out of place in formal writing.
- Common friendly sign-offs like um abração and um beijão are standard, warm, and not at all rough or aggressive in Portuguese.
