A superlative sentence (frase superlativa) picks one element out of a group and says it stands at the extreme — the tallest, the most expensive, the least comfortable. Portuguese, like English, splits superlatives into two very different kinds. The relative superlative (superlativo relativo) compares against a specific reference set — the tallest in the class, the cheapest of the three. The absolute superlative (superlativo absoluto) just intensifies the quality without comparing at all — extremely tall, incredibly cheap. Both are everyday tools in Portuguese, but the absolute has a peculiarity English speakers do not have a direct match for: Portuguese can turn almost any adjective into a one-word intensified form with the suffix -íssimo (altíssimo, caríssimo, facílimo). Learning to recognize and use this suffix is a small rite of passage — it is the point at which learners start to sound Portuguese rather than just speaking it correctly.
The quick answer
For the relative superlative ("the most / the least X of a group"), use o/a/os/as mais or o/a/os/as menos + adjective, followed by a de-phrase naming the reference set: o mais alto da turma (the tallest in the class). For the absolute superlative ("extremely X"), you have two options: the analytical muito / extremamente / bastante + adjective (everyday speech), or the synthetic suffix -íssimo attached directly to the adjective (slightly more emphatic and, for some speakers, mildly formal). A small set of adjectives — ótimo, péssimo, máximo, mínimo, supremo, ínfimo — are irregular synthetic superlatives that learners need to memorise.
É o mais alto da turma.
He's the tallest in the class.
A sopa está muito boa hoje.
The soup is very good today.
The relative superlative: o mais / o menos + de
The relative superlative picks out the extreme member of a known group. The structure is rigid:
definite article + (noun) + mais/menos + adjective + de + reference set
The definite article (o, a, os, as) is what makes this a superlative rather than a simple comparative. Without the article, mais alto just means taller; with the article, o mais alto means the tallest.
A Ana é a mais inteligente da turma.
Ana is the most intelligent in the class.
O Porto é o menos quente dos destinos que vimos.
Porto is the least hot of the destinations we looked at.
Este é o restaurante mais barato da zona.
This is the cheapest restaurant in the area.
Aquele foi o filme mais triste que já vi.
That was the saddest film I've ever seen.
Notice the last two examples. When the superlative includes an explicit noun (restaurante, filme), the noun sits between the article and mais/menos: o restaurante mais barato, not o mais barato restaurante. The English word order — the cheapest restaurant — puts the adjective before the noun; Portuguese puts it after.
The de-phrase: naming the reference set
The de-phrase (de + noun/clause) tells the listener against what group the extreme is being measured. It can be dropped when context makes it obvious, but it is grammatically central to the construction.
| De-phrase | Example | Meaning |
|---|---|---|
| da turma | o mais alto da turma | the tallest in the class |
| do mundo | o rio mais longo do mundo | the longest river in the world |
| de todos | o mais bonito de todos | the most beautiful of all |
| que conheço | a pessoa mais simpática que conheço | the nicest person I know |
| que já vi | o pior filme que já vi | the worst film I've ever seen |
O Douro é um dos rios mais bonitos de Portugal.
The Douro is one of the most beautiful rivers in Portugal.
É a melhor amiga que tenho.
She's the best friend I have.
Este é o livro mais interessante que li este ano.
This is the most interesting book I've read this year.
Notice that when the de-phrase is a clause (que conheço, que já vi, que li), Portuguese uses the indicative — not the subjunctive — in straightforward statements of fact. The subjunctive appears only when the superlative is hypothetical or negated: é a coisa mais estranha que ele possa ter dito (it's the strangest thing he might have said).
With irregular comparatives
The four irregular comparatives (melhor, pior, maior, menor) serve double duty as superlatives — you simply add the definite article.
| Adjective | Comparative | Relative superlative |
|---|---|---|
| bom (good) | melhor (better) | o melhor (the best) |
| mau (bad) | pior (worse) | o pior (the worst) |
| grande (big) | maior (bigger) | o maior (the biggest) |
| pequeno (small) | menor / mais pequeno | o menor / o mais pequeno |
É o melhor jogador do clube.
He's the best player in the club.
Foi o pior dia da minha vida.
It was the worst day of my life.
Lisboa é a maior cidade de Portugal.
Lisbon is the biggest city in Portugal.
Este é o quarto mais pequeno da casa.
This is the smallest room in the house.
As with plain comparatives, European Portuguese prefers mais pequeno for concrete physical size and reserves menor for abstract or figurative smallness: o menor dos males (the lesser of two evils), a menor alteração (the slightest change). In fact, o mais pequeno is more common in everyday PT-PT speech than o menor.
The absolute superlative: extremely X
The absolute superlative does not compare against a reference set. It simply intensifies the adjective — roughly equivalent to English very, extremely, incredibly. Portuguese offers two ways to build it: the analytical (periphrastic) form and the synthetic (one-word) form in -íssimo.
Analytical absolute superlative: muito / extremamente / bastante
The everyday pattern is simply muito + adjective, or one of its stronger cousins (extremamente, bastante, imenso, super-).
O café em Portugal é muito bom.
Coffee in Portugal is very good.
A conferência foi extremamente interessante.
The conference was extremely interesting.
Estou bastante cansado depois do voo.
I'm quite tired after the flight.
Esta casa é imensa!
This house is huge!
Ele é super simpático.
He's super nice. (informal)
| Intensifier | Register | Strength |
|---|---|---|
| muito | neutral | "very" — the default |
| bastante | neutral | "quite" / "pretty" — slightly less strong than muito |
| imenso | (informal) | "hugely" — warm, conversational |
| extremamente | (formal) | "extremely" — careful, written |
| super- | (informal) | "super" — common with young speakers |
| altamente | (formal) | "highly" — mostly with evaluative adjectives |
| -íssimo (see below) | neutral | "extremely" — emphatic, one-word |
Synthetic absolute superlative: the -íssimo suffix
This is where Portuguese does something English does not have a clean equivalent for. Take almost any adjective, attach -íssimo (with gender and number agreement), and you get a one-word emphatic form.
| Adjective | Synthetic superlative | Meaning |
|---|---|---|
| alto | altíssimo | extremely tall |
| baixo | baixíssimo | extremely low |
| bonito | bonitíssimo | extremely pretty |
| caro | caríssimo | extremely expensive |
| feliz | felicíssimo | extremely happy |
| fácil | facílimo | extremely easy |
| lento | lentíssimo | extremely slow |
| rico | riquíssimo | extremely rich |
| simples | simplicíssimo | extremely simple |
Esta sopa está boníssima.
This soup is incredibly good.

Traffic today is awful — I'm going to be super late.
O exame foi facílimo, não te preocupes.
The exam was a piece of cake, don't worry.
Aquele restaurante é caríssimo, nem pensem.
That restaurant is ridiculously expensive — forget about it.
Spelling changes in -íssimo forms
The suffix itself is regular, but the stem often shifts for phonological reasons. Learning the main patterns saves a lot of guesswork:
| Final letter(s) of adjective | Change | Example |
|---|---|---|
| -o (most adjectives) | drop -o, add -íssimo | alto → altíssimo, caro → caríssimo |
| -vel | -vel → -bilíssimo | amável → amabilíssimo, terrível → terribilíssimo |
| -z | -z → -císsimo | feliz → felicíssimo, capaz → capacíssimo |
| -c- / -g- (hard sound) | c → qu, g → gu (preserves hard sound) | rico → riquíssimo, longo → longuíssimo |
| -m | -m → -níssimo | comum → comuníssimo, bom → boníssimo (also ótimo) |
| -ão | -ão → -aníssimo | são → saníssimo, cristão → cristianíssimo |
O projeto é amabilíssimo da parte deles.
The project is extremely kind of them.
É um problema terribilíssimo.
It's an absolutely terrible problem.
Aquele homem é felicíssimo desde que se reformou.
That man has been incredibly happy since he retired.
Latinate stems: a PT-PT specialty
European Portuguese has held onto a small set of learned Latinate stems in the synthetic superlative that Brazilian Portuguese has largely dropped. These sound educated, slightly formal, and are recognisably PT-PT.
| Adjective | Everyday form | Latinate form (PT-PT) | Register |
|---|---|---|---|
| amigo (friendly) | amiguíssimo | amicíssimo | literary/formal |
| nobre (noble) | nobilíssimo / nobríssimo | nobilíssimo | literary/formal |
| cruel (cruel) | cruelíssimo | crudelíssimo | literary |
| pobre (poor) | pobríssimo | paupérrimo | literary/formal |
| célebre (famous) | — | celebérrimo | literary/formal |
| sagrado (sacred) | sagradíssimo | sacratíssimo | ecclesiastical |
| antigo (old) | antiguíssimo | antiquíssimo | literary/formal |
O jornalista é celebérrimo em Portugal. (formal)
The journalist is extremely well-known in Portugal.
Vivia numa casa paupérrima nos arredores. (literary)
He lived in an extremely poor house on the outskirts.
O templo é sacratíssimo para a comunidade.
The temple is most sacred to the community.
You will not need to produce these in speech. But you should recognise them when reading — they appear in newspapers, in literary prose, and in the speech of educated older speakers.
Irregular synthetic superlatives to memorise
Four adjectives have irregular one-word absolute superlatives that have fully lexicalised — they work as standalone words and should be memorised as units. Importantly, they also function as the superlative counterparts of the irregular comparatives melhor, pior, maior, menor.
| Adjective | Comparative | Absolute superlative | Meaning |
|---|---|---|---|
| bom (good) | melhor | ótimo | excellent, great |
| mau (bad) | pior | péssimo | terrible, awful |
| grande (big) | maior | máximo | maximum, utmost |
| pequeno (small) | menor | mínimo | minimum, least |
| alto (high) | superior | supremo / sumo | supreme |
| baixo (low) | inferior | ínfimo | lowest, tiniest |
O jantar estava ótimo — obrigado por nos receberes.
The dinner was excellent — thanks for having us.
A ligação do Wi-Fi está péssima hoje.
The Wi-Fi connection is terrible today.
Ganhei o prémio máximo no concurso.
I won the top prize in the competition.
Não tenho a mínima ideia do que aconteceu.
I haven't got the slightest idea what happened.
Ficou numa posição ínfima depois da reestruturação.
He ended up in the lowest position after the restructuring.
Under AO90 orthography, ótimo is written without the p — the older óptimo spelling is no longer standard in European Portuguese. Same for ótica (not óptica) and several similar words.
Register: when to use which form
The relative superlative is register-neutral and appears everywhere. The absolute superlative forms split by register:
| Form | Register | Typical context |
|---|---|---|
| muito + adj | neutral | Everyday speech, any writing |
| bastante + adj | neutral | Moderate intensification, all contexts |
| imenso + adj | (informal) | Spoken PT-PT, affectionate emphasis |
| super + adj | (informal) | Young speech, casual texts |
| -íssimo | neutral with emphatic colour | Exclamations, emphatic speech, any writing |
| extremamente + adj | (formal) | Formal writing, careful speech |
| altamente + adj | (formal) | Evaluative: altamente recomendado |
| Latinate -íssimo (paupérrimo, celebérrimo) | (literary) | Journalism, essays, literature |
| ótimo, péssimo, máximo, mínimo | neutral | Everyday — fully lexicalised |
Despite what older textbooks suggest, the -íssimo suffix is completely natural in spoken European Portuguese for emphasis. A speaker saying o bolo estava boníssimo or estou cansadíssimo sounds fully native — if anything, a bit warmer and more expressive than the plain muito bom / muito cansado. The suffix is productive; new words can take it on (giríssimo from giro, fixíssimo from fixe, both teen-slang superlatives of everyday adjectives).
Ele é fixíssimo, vais gostar dele.
He's super cool, you'll like him. (informal young speech)
A festa ontem foi giríssima.
The party yesterday was really fun.
Superlative of adverbs
Adverbs can also take superlative forms, but the mechanics are slightly different. For the relative superlative, use o mais / o menos + adverb + possível or + a clause.
Corre o mais depressa possível.
Run as fast as possible.
Fala o mais baixo que puderes.
Speak as quietly as you can.
Responde-me o mais cedo possível, por favor.
Get back to me as early as possible, please.
For the absolute superlative of adverbs, either attach -íssimo directly (when the adverb ends in -mente or has an -o stem) or use a periphrastic intensifier.
Ele fala rapidíssimo — custa a acompanhar.
He speaks extremely fast — it's hard to keep up.
Chegámos tardíssimo ao aeroporto.
We got to the airport really late.
Ela canta muito bem.
She sings very well. (periphrastic — the -íssimo form otimamente is unusual)
With bem and mal, the synthetic forms otimamente and pessimamente exist but are much less common than the periphrastic muito bem / muito mal. Just use the periphrastic form. Note the spelling: adverbs in -mente drop the graphical accent of the base adjective because the stress shifts to -men- (so ótima → otimamente, péssima → pessimamente).
The "superlative of + a superlative" pattern
Portuguese often stacks a superlative within a superlative for expressive effect: o melhor dos melhores, a maior das maiores, o pior dos piores. This is an emphatic idiomatic pattern, common in sports commentary, reviews, and storytelling.
Foi o melhor dos melhores concertos que já vi.
It was the best of the best concerts I've ever seen.
Este é o pior dos piores filmes do ano.
This is the worst of the worst films of the year.
Conheceu o amor dos amores na Madeira.
He met the love of his life in Madeira.
Plural agreement
Both the relative and absolute superlatives agree in gender and number with the noun they describe. Learners sometimes forget the feminine plural, especially with irregular forms.
São as casas mais bonitas da aldeia.
They're the prettiest houses in the village.
Estas notícias são péssimas.
This news is terrible.
As mais altas do grupo são a Ana e a Inês.
The tallest in the group are Ana and Inês.
Os salários são baixíssimos neste setor.
Salaries are extremely low in this sector.
Common Mistakes
❌ Ele é mais alto da turma.
Missing definite article — the relative superlative needs 'o'.
✅ Ele é o mais alto da turma.
He's the tallest in the class.
❌ É o mais bom filme do ano.
Incorrect — bom is irregular; use melhor.
✅ É o melhor filme do ano.
It's the best film of the year.
❌ Esta sopa está muito boníssima.
Redundant — -íssimo already means 'extremely'; don't add muito.
✅ Esta sopa está boníssima. / Esta sopa está muito boa.
This soup is extremely good.
❌ O trânsito está muito péssimo.
Redundant — péssimo means 'awful' on its own.
✅ O trânsito está péssimo.
Traffic is awful.
❌ É um restaurante caríssima.
Wrong agreement — restaurante is masculine, so caríssimo.
✅ É um restaurante caríssimo.
It's an extremely expensive restaurant.
❌ É o mais alto em toda a turma.
Incorrect preposition — the reference set takes 'de', not 'em'.
✅ É o mais alto de toda a turma.
He's the tallest in the whole class.
❌ Está óptimo o café.
Outdated spelling — AO90 removes the 'p'.
✅ Está ótimo o café.
The coffee is excellent.
Key Takeaways
- Relative superlative: definite article + mais / menos
- adjective + de
- reference set: o mais alto da turma. The de-phrase is the diagnostic feature.
- adjective + de
- Absolute superlative: intensifies without comparing. Two main routes: periphrastic (muito / extremamente / bastante + adj) or synthetic (-íssimo).
- The -íssimo suffix is productive and fully natural in spoken PT-PT, carrying emphatic warmth. It agrees in gender and number.
- Stem changes with -íssimo follow predictable patterns: rico → riquíssimo, feliz → felicíssimo, amável → amabilíssimo, bom → boníssimo.
- Memorise the irregulars: ótimo (excellent), péssimo (awful), máximo (greatest), mínimo (least), supremo/sumo, ínfimo.
- European Portuguese preserves Latinate stems (paupérrimo, celebérrimo, amicíssimo, nobilíssimo) as a formal/literary register — recognise these in reading.
- Under AO90, ótimo (not óptimo), ótica, receção — the silent consonants drop.
- Do not double-intensify: muito péssimo and muito boníssimo are redundant. Pick one device.
