Portuguese — Essential grammar

Abbreviations used in this guide

Each example below has three parts: the original text, a literal gloss describing how every word works, and a natural translation. The glosses use a few shorthand labels so they stay short. Don't worry about memorising them — this is a reference you can come back to. Person and number · 1sg / 2sg / 3sg — first / second / third person singular (I, you, he/she/it) · 1pl / 2pl / 3pl — first / second / third person plural (we, you-all, they) Gender and case · m / f / n — masculine / feminine / neuter · sg / pl — singular / plural · m.sg — combined: masculine singular (and similarly f.pl, n.sg, etc.) · NOM / ACC / GEN / DAT / INS / LOC — grammatical cases (nominative/accusative/genitive/dative/instrumental/locative) — which role the word plays in the sentence Tense and aspect · PRES — present · PRET — preterite (a finished past event) · IMPF — imperfect (an ongoing or habitual past situation) · FUT — future · PERF — perfect (an action completed with present relevance) · PROG — progressive (action in progress, e.g. am eating) · COND — conditional (would…) Mood · IND — indicative (regular statement) · SUBJ — subjunctive (uncertainty, wishes, doubts) · IMP — imperative (commands) · INF — infinitive (dictionary form: to go, to eat) Other · REFL — reflexive (action on oneself: myself, yourself) · PERS — personal a (Spanish only — marks a human direct object) · HON — honorific (extra-polite form, common in Japanese/Korean) · TOP / SUB / OBJ — topic / subject / object markers (Japanese, Korean) · CL — classifier (Chinese, Japanese, Korean — a counter word for nouns) · NEG — negation

Word order

Portuguese basic word order is Subject-Verb-Object (SVO), the same as English. Like its Romance siblings, Portuguese is a pro-drop language: the subject pronoun is normally omitted because the verb ending identifies the person. Including the pronoun adds emphasis or disambiguates (especially in the third person, where ele/ela/voce share the same verb form). Adverbs and prepositional phrases move relatively freely; subjects can also follow the verb, particularly with intransitive verbs (Chegou o trem). Object and clitic pronoun placement, however, follows strict rules that differ between Brazilian (BR) and European (PT) usage.

  • Falo portugues. — speak-1sg Portuguese
    I speak Portuguese.
  • A Maria come pao. — the Maria eats bread
    Maria eats bread.
  • Chegou o trem. — arrived the train — VS order
    The train arrived.

Articles

Articles agree with the noun in gender (masculine/feminine) and number. Definite ('the'): o (m.sg), a (f.sg), os (m.pl), as (f.pl). Indefinite ('a/an/some'): um (m.sg), uma (f.sg), uns (m.pl), umas (f.pl). Portuguese contracts articles obligatorily with the prepositions de, em, a, por: de+o=do, de+a=da, em+o=no, em+a=na, a+o=ao, a+a=a (with grave accent), por+o=pelo, por+a=pela. The definite article is also used before personal names in colloquial speech (especially in PT and southern BR: o Joao, a Maria) and before possessives in PT (o meu livro), while BR often drops it (meu livro).

  • O livro esta na mesa. — the book is in-the table
    The book is on the table.
  • Vou ao mercado. — go-1sg to-the market — a+o=ao
    I'm going to the market.
  • O meu carro e novo. (PT) / Meu carro e novo. (BR) — (the) my car is new
    My car is new.

Pronouns

Subject: eu, tu (PT, intimate) / voce (BR, neutral), ele/ela, nos / a gente (BR colloquial), vos (archaic) / voces, eles/elas. Direct object: me, te, o/a, nos, vos, os/as. Indirect object: me, te, lhe, nos, vos, lhes. Reflexive: me, te, se, nos, vos, se. Placement is the major BR/PT split: BR strongly prefers proclisis (pronoun before the verb, even at sentence start: Me chamo Ana), while PT requires enclisis in neutral affirmative sentences (Chamo-me Ana) and proclisis only after triggers like negation, subordinators, or wh-words (Nao me chamo Ana). In BR speech, third-person o/a/lhe are often replaced by ele/ela or simply dropped.

  • Me chamo Ana. (BR) — REFL-1sg call-1sg Ana — proclisis
    My name is Ana.
  • Chamo-me Ana. (PT) — call-1sg-REFL Ana — enclisis
    My name is Ana.
  • Nao o vi ontem. — not him saw-1sg yesterday
    I didn't see him yesterday.

Noun gender and adjective agreement

Every noun is masculine or feminine. Typical endings: -o is usually masculine (livro, carro), -a usually feminine (casa, mesa); -agem, -dade, -cao are feminine (viagem, cidade, nacao); -ma of Greek origin is masculine (problema, sistema). Adjectives agree in gender and number with the noun and normally follow it: um livro novo, uma casa nova, livros novos, casas novas. Some adjectives are invariable in gender (-e, -l, -z: inteligente, facil, feliz) and only mark number. A few adjectives change meaning by position: um grande homem (a great man) vs um homem grande (a big man). Past participles used as adjectives also agree.

  • Uma casa branca. — a-f.sg house white-f.sg
    A white house.
  • Os meninos sao inteligentes. — the-m.pl boys are intelligent-pl
    The boys are intelligent.
  • Um grande homem. — a great man — pre-noun = figurative
    A great man.

Verb conjugation patterns

Infinitives end in -ar (1st conjugation: falar), -er (2nd: comer), or -ir (3rd: partir). Endings encode person, number, tense, mood, and aspect — usually making the subject pronoun redundant. Portuguese famously preserves a personal infinitive (inflected for subject) absent from Spanish and French. Key irregular verbs to memorize: ser ('to be', essential/permanent), estar ('to be', state/location), ter ('to have', also auxiliary for compound tenses), ir ('to go', auxiliary for periphrastic future), haver ('there to be', existential and archaic perfect auxiliary), fazer ('to do/make'), dizer ('to say'), poder ('can'), querer ('to want'), ver ('to see'), vir ('to come'). Stem changes also affect many -ir verbs (dormir: durmo, dormes...).

  • Falar: falo, falas, fala, falamos, falais, falam. — to speak — present indicative
    I speak, you speak, etc.
  • Comer: como, comes, come, comemos, comeis, comem. — to eat — present indicative
    I eat, you eat, etc.
  • Partir: parto, partes, parte, partimos, partis, partem. — to leave — present indicative
    I leave, you leave, etc.

Present tense

The presente do indicativo describes habitual actions, general truths, and (unlike English simple present) actions happening right now. Endings: -ar verbs take -o, -as, -a, -amos, -ais, -am; -er verbs -o, -es, -e, -emos, -eis, -em; -ir verbs -o, -es, -e, -imos, -is, -em. The tu form is alive in PT and parts of BR; elsewhere BR replaces it with voce + 3rd-singular verb. To stress an action in progress, Portuguese uses estar + gerundio (BR: estou falando) or estar a + infinitivo (PT: estou a falar). The present can also express scheduled near-future events: Amanha viajo para o Rio ('I'm travelling to Rio tomorrow').

  • Eu falo portugues todos os dias. — I speak-1sg Portuguese all the days
    I speak Portuguese every day.
  • Estou falando com ela. (BR) — am-1sg speaking with her
    I'm speaking with her.
  • Estou a falar com ela. (PT) — am-1sg to speak with her
    I'm speaking with her.

Past — preterito perfeito vs imperfeito

Portuguese distinguishes two main simple past tenses. The preterito perfeito (simple) reports completed, bounded actions: 'I ate', 'we arrived'. Endings: -ar -ei, -aste, -ou, -amos/-amos, -astes, -aram; -er/-ir -i, -este, -eu/-iu, -emos/-imos, -estes, -eram. The preterito imperfeito describes ongoing, habitual, or background past states: 'I used to eat', 'it was raining'. Endings: -ar -ava, -avas, -ava, -avamos, -aveis, -avam; -er/-ir -ia, -ias, -ia, -iamos, -ieis, -iam. Note: Portuguese 'falei' covers both English 'I spoke' and 'I have spoken' — the compound 'tenho falado' carries the special meaning 'I've been speaking (repeatedly, lately)'.

  • Ontem comi peixe. — yesterday ate-1sg.PERF fish
    Yesterday I ate fish.
  • Quando era crianca, comia muito peixe. — when was-IMPF child, ate-IMPF much fish
    When I was a child, I used to eat a lot of fish.
  • Tenho lido esse livro. — have-1sg read-PP that book — recent ongoing
    I've been reading that book (lately).

Future tense

Portuguese has two main futures. The synthetic future (futuro do presente) attaches endings to the full infinitive: -ei, -as, -a, -emos, -eis, -ao (falarei, falaras, falara...). It sounds formal/written; in speech, both BR and PT prefer the periphrastic ir + infinitivo: vou falar ('I'm going to speak'). The synthetic future is also used to express conjecture in the present (Sera verdade? 'Could it be true?'). The conditional (futuro do preterito), formed with the same root and endings -ia, -ias, -ia, -iamos, -ieis, -iam (falaria), expresses hypothetical situations. A handful of verbs have contracted future stems: dizer -> direi, fazer -> farei, trazer -> trarei.

  • Amanha vou falar com ele. — tomorrow go-1sg to speak with him
    Tomorrow I'm going to speak with him.
  • Falarei com o diretor amanha. — speak-1sg.FUT with the director tomorrow
    I will speak with the director tomorrow.
  • Sera que ela vem? — be-3sg.FUT that she comes — conjecture
    I wonder if she's coming?

Ser vs estar

Like Spanish, Portuguese has two verbs for 'to be'. Ser expresses essential, defining, or permanent attributes: identity, origin, profession, nationality, material, time/date, possession (Sou medico, E de Lisboa, A mesa e de madeira). Estar expresses states, conditions, locations, and temporary situations (Estou cansado, A chave esta na mesa). The contrast often parallels English 'is' vs 'is currently/feels': Ele e nervoso = he's a nervous person; Ele esta nervoso = he's nervous right now. Permanent location of buildings/cities uses ficar or ser (Lisboa fica em Portugal). Estar is also the auxiliary for progressive aspect (estar + gerundio/a + infinitivo).

  • Sou brasileiro. — am-SER Brazilian — identity
    I am Brazilian.
  • Estou cansado. — am-ESTAR tired — state
    I am tired.
  • O cafe e quente / O cafe esta quente. — the coffee is hot — by nature / right now
    Coffee is hot (in general) / The coffee is hot (now).

Negation

Standard negation places nao directly before the verb (or before any clitic pronoun attached to it): Nao falo ingles. Object pronouns sit between nao and the verb in proclisis: Nao me viu. Portuguese uses double negation freely when a negative word follows the verb: Nao vi ninguem ('I didn't see anyone' — literally 'not saw nobody'); Nao tenho nada. If the negative word precedes the verb, nao is dropped: Ninguem veio. In BR colloquial speech, an emphatic clause-final nao is common: Nao sei nao ('I really don't know'). Other negatives: nunca (never), jamais (never/ever), nada (nothing), nenhum/-a (no, none), nem (nor, not even).

  • Nao falo ingles. — not speak-1sg English
    I don't speak English.
  • Nao vi ninguem. — not saw-1sg nobody — double negative
    I didn't see anyone.
  • Nao sei nao. (BR) — not know-1sg no — emphatic
    I really don't know.

Questions

Yes/no questions are formed simply by rising intonation; word order stays SVO. Voce fala portugues? Subject-verb inversion is not required (though possible in writing). Wh-questions use interrogatives: o que / que (what), quem (who), onde (where), quando (when), como (how), por que (why; BR also spelled porque/por que/porque depending on position; PT writes porque), quanto/-a (how much), qual / quais (which). BR frequently inserts the focusing 'e que' after the wh-word: Onde e que voce mora? ('Where do you live?'). The bare form Onde voce mora? is also fine. Echo questions and tag questions use nao e? (often pronounced 'ne?' in BR).

  • Voce fala portugues? — you speak Portuguese? — rising intonation
    Do you speak Portuguese?
  • Onde e que voce mora? (BR) — where is that you live
    Where do you live?
  • Esta bom, nao e? — is good, no is? — tag
    It's good, isn't it?

Plural of nouns

Most nouns add -s for the plural: livro -> livros, casa -> casas. Nouns ending in -r, -s, -z add -es: mulher -> mulheres, mes -> meses, luz -> luzes. Most ending in -m change -m to -ns: homem -> homens, jardim -> jardins. Nouns ending in -al, -el, -ol, -ul drop -l and add -is: animal -> animais, papel -> papeis, lencol -> lencois, paul -> pauis. Nouns ending in -il stressed change to -is (funil -> funis); unstressed -il becomes -eis (facil -> faceis). Nouns ending in -ao have three plural patterns: -oes (the commonest: cancao -> cancoes), -aes (pao -> paes), and -aos (mao -> maos) — these must be memorized.

  • livro -> livros; mulher -> mulheres. — regular plurals
    book -> books; woman -> women.
  • animal -> animais; papel -> papeis. — -l -> -is
    animal -> animals; paper -> papers.
  • pao -> paes; mao -> maos; cancao -> cancoes. — three -ao plural patterns
    bread -> breads; hand -> hands; song -> songs.

Reflexive verbs

Reflexive verbs take a pronoun (me, te, se, nos, vos, se) that refers back to the subject. Many describe daily routines: chamar-se (to be called), levantar-se (to get up), deitar-se (to lie down/go to bed), lavar-se (to wash), vestir-se (to get dressed), sentar-se (to sit down), lembrar-se (to remember), esquecer-se (to forget). The infinitive is usually cited with the clitic attached by a hyphen. In actual sentences, placement again splits by variant: BR prefers proclisis (Eu me chamo Pedro), PT enclisis in neutral affirmatives (Eu chamo-me Pedro). After negatives, conjunctions, and wh-words, both variants use proclisis: Nao me lembro. Reciprocal reflexives mean 'each other': Eles se amam / amam-se.

  • Eu me chamo Pedro. (BR) — I REFL call-1sg Pedro
    My name is Pedro.
  • Eu chamo-me Pedro. (PT) — I call-1sg-REFL Pedro
    My name is Pedro.
  • Nao me lembro do nome dele. — not REFL remember-1sg of-the name his
    I don't remember his name.

Personal pronouns and clitic placement

The 2nd-person system varies sharply by region. PT keeps tu (informal singular) with proper 2nd-person verb forms (tu falas) and uses voce as a polite/formal alternative. BR has mostly lost tu (except in the South and Northeast, often with 3rd-singular verbs: tu fala) and uses voce as the all-purpose 'you'. Formal address in both variants uses o senhor / a senhora ('sir/madam'), always with 3rd-person verbs: O senhor pode me ajudar? Clitic placement (me, te, se, lhe, o/a...) is the largest written-grammar split: BR proclisis is the default everywhere; PT enclisis is the default, with proclisis triggered by negation, subordinators, wh-words, certain adverbs (ja, sempre, talvez), and indefinites. After future/conditional verbs, PT inserts the clitic into the middle of the verb (mesoclisis): dar-lhe-ei ('I will give to him/her').

  • Voce pode me ajudar? (BR) / Podes ajudar-me? (PT, tu) — can you help me — BR proclisis / PT enclisis
    Can you help me?
  • O senhor fala ingles? — the gentleman speaks English — formal
    Do you speak English, sir?
  • Dar-lhe-ei o livro. (PT) — give-him-FUT.1sg the book — mesoclisis
    I will give him the book.

Nasal vowels

Portuguese has a rich set of nasal vowels written with a tilde (ã, õ) or by a vowel followed by m or n in the syllable coda (sim, bom, dente). Nasalized vowels are pronounced through the nose without fully closing the mouth — there is no English-style 'ng' consonant at the end. The diphthong ão (as in pão, não) is the most distinctive sound: a strongly nasalized 'ow' glide. Its plural ões (canções) and the feminine ã (maçã, irmã) follow the same nasal quality. Other key nasal diphthongs: ãe (mãe, pães), õe (põe), ui (muito is pronounced 'muĩtu'). Mastering nasal vowels is essential: pão (bread) vs pau (stick), não (no) vs nau (ship) are distinguished only by nasalization.

  • pao, mae, coracao — pão, mãe, coração — nasal diphthongs
    bread, mother, heart.
  • sim, bom, com — vowel + m = nasal vowel
    yes, good, with.
  • nao vs nau; pao vs pau — não/nau, pão/pau — nasal vs oral
    no/ship; bread/stick.
