O prato limpo está no armário, e os garfos estão na gaveta.

Because o is the masculine singular definite article (the), while os is the masculine plural definite article.

• o prato = the plate
• os garfos = the forks

In Portuguese, the article changes for gender and number:

• o = masculine singular
• a = feminine singular
• os = masculine plural
• as = feminine plural

In Portuguese, adjectives often come after the noun.

So:

• prato limpo = clean plate

This is a very normal word order in Portuguese. Sometimes adjectives can come before the noun, but that may sound more literary, emphatic, or change the nuance. For a basic descriptive meaning, noun + adjective is the most common pattern.

Because prato is a masculine noun, so the adjective must agree with it.

• prato limpo = masculine singular
• gaveta limpa = feminine singular
• pratos limpos = masculine plural
• gavetas limpas = feminine plural

This is called adjective agreement. In Portuguese, adjectives usually match the noun in gender and number.

Both come from the verb estar (to be), but they agree with different subjects:

• está = is for he/she/it or a singular thing
• estão = are for they or plural things

In the sentence:

• O prato limpo está no armário = The clean plate is in the cabinet
• Os garfos estão na gaveta = The forks are in the drawer

So the verb changes depending on whether the subject is singular or plural.

Because Portuguese usually uses estar for location.

• está no armário = is in the cabinet
• estão na gaveta = are in the drawer

A very useful beginner rule is:

• ser = identity, permanent characteristics, origin, time, etc.
• estar = location, condition, temporary states

So for where something is, estar is normally the correct choice.

They mean in the, and they are contractions.

• no = em + o
• na = em + a

So:

• no armário = in the cabinet
• na gaveta = in the drawer

Portuguese very commonly contracts prepositions with articles:

• em + o = no
• em + a = na
• em + os = nos
• em + as = nas

Because armário is masculine and gaveta is feminine.

That affects the article:

• o armário → em + o armário = no armário
• a gaveta → em + a gaveta = na gaveta

You usually have to learn the gender of each noun along with the noun itself. A good habit is to memorize vocabulary with the article:

• o armário
• a gaveta
• o prato
• o garfo

Garfos is the plural of garfo.

For many Portuguese nouns, the plural is formed by adding -s:

• garfo → garfos
• prato → pratos
• gaveta → gavetas

The article and verb also change to match the plural:

• o garfo está
• os garfos estão

So Portuguese marks plurality in several places, not just on the noun.

Portuguese uses definite articles more often than English does. In this sentence, using the articles is completely natural:

• o prato limpo
• os garfos

English sometimes says things like Clean plate is in the cabinet only in very special contexts, but normally it would also use the here. In Portuguese, leaving out the article in this sentence would sound unnatural.

So for everyday sentences like this, keep the article.

Armário is pronounced roughly like ar-MA-ryoo in Brazilian Portuguese.

The accent mark in á shows the stressed syllable:

• ar-MÁ-rio

Without the accent, the stress rules would suggest a different pronunciation. So the written accent helps you know where the emphasis goes.

Also, in Brazilian Portuguese, the final -o often sounds closer to oo than to a strong English oh.

Yes. Portuguese word order is fairly flexible, especially in simple statements like this.

For example, you could say:

• Os garfos estão na gaveta, e o prato limpo está no armário.

That still means the same thing, just with the items mentioned in a different order.

However, inside each clause, the basic order subject + verb + location is the most neutral and natural:

• O prato limpo está no armário.
• Os garfos estão na gaveta.

E means and.

It connects the two clauses:

• O prato limpo está no armário
• os garfos estão na gaveta

So the full sentence simply joins two related statements together with and.

Yes. That would mean inside the cabinet or inside the drawer, and it can sound a little more explicit.

Compare:

• no armário = in the cabinet

• dentro do armário = inside the cabinet

• na gaveta = in the drawer
• dentro da gaveta = inside the drawer

In many everyday situations, no / na is enough and sounds perfectly natural. Dentro de is used when you want to emphasize that something is physically inside.
