O formulário está completo agora.

O means the. Portuguese usually uses definite articles more often than English does, so o formulário is simply the form.

• o = the for a masculine singular noun
• a = the for a feminine singular noun
• os / as = the for plural nouns

Because formulário is masculine singular, it takes o.

The noun is formulário, which means form in the sense of a document or questionnaire.

A few useful points:

• It is a masculine noun
• It has an accent mark: formulário
• The final -o often goes with masculine nouns, though not always

So:

• o formulário = the form
• um formulário = a form

The accent mark in formulário shows which syllable is stressed.

It is pronounced with the stress on lá:

• for-mu-LÁ-ri-o

Without the accent, the stress pattern would be different or the word might not follow normal spelling rules. In Portuguese, accents are very important for correct pronunciation.

This is one of the most common questions in Portuguese.

Portuguese has two main verbs for to be:

• ser → used for identity, permanent traits, definitions, origin, time, etc.
• estar → used for states, conditions, locations, and things seen as temporary or current

Here, completo means complete as a current state or condition of the form, so Portuguese uses estar:

• O formulário está completo agora.
• The form is complete now.

Using é would sound less natural here, because the sentence is talking about the form’s current status, not its essential nature.

Está is the he/she/it form of estar in the present tense:

• eu estou
• você/ele/ela está
• nós estamos
• vocês/eles/elas estão

The accent helps show the correct stress and spelling. It is a normal part of this verb form.

In this sentence, the subject is o formulário, which is singular, so está is the correct form.

Adjectives in Portuguese usually agree with the noun they describe in gender and number.

Since formulário is masculine singular, the adjective must also be masculine singular:

• o formulário completo
• o formulário está completo

Compare:

• a ficha está completa = the form/card is complete
• os formulários estão completos = the forms are complete
• as fichas estão completas = the cards/forms are complete

Yes. In Portuguese, after verbs like ser and estar, adjectives normally come after the verb, just as in English:

• The form is complete
• O formulário está completo

So this part is actually very similar to English.

Also, adjectives often come after nouns in Portuguese:

• um formulário completo = a complete form

But in your sentence, completo is not directly attached to the noun in a noun phrase. It is describing the subject after the verb está.

Agora means now.

In this sentence, it tells you that the form is complete at this moment:

• O formulário está completo agora.
• The form is complete now.

It can also sometimes mean nowadays or at this point, depending on context, but here it simply means now.

Putting agora at the end is completely natural in Portuguese. It works a lot like English now in The form is complete now.

You could also hear:

• Agora o formulário está completo.
• O formulário agora está completo.

These are possible, but they may slightly change the emphasis:

• Agora o formulário está completo. → emphasizes now
• O formulário está completo agora. → neutral and natural

Yes, if the idea of now is not important.

• O formulário está completo. = The form is complete.
• O formulário está completo agora. = The form is complete now.

Adding agora makes it clearer that the form was perhaps incomplete before, but has reached that state now.

No. The subject here is not you. The subject is o formulário.

Portuguese does not need to include a person like you unless that is actually the subject. This sentence is simply about the form itself:

• O formulário = subject
• está = verb
• completo = adjective
• agora = time adverb

To make it plural, both the article, noun, verb, and adjective must agree:

• Os formulários estão completos agora.
• The forms are complete now.

Changes:

• o → os
• formulário → formulários
• está → estão
• completo → completos

A simple pronunciation guide is:

O formulário está completo agora
→ oo for-moo-LAH-ryoo es-TAH kom-PLEH-too a-GOH-rah

A few notes:

• O often sounds like oo
• rio in formulário is not like English rio; it is smoother
• está has stress on the last syllable
• agora has stress on go

Pronunciation varies a bit by region in Brazil, but this guide is a good starting point.
