O churrasqueiro está perto da churrasqueira.

Because Portuguese usually uses estar for location.

• estar = to be, for location, temporary states, conditions
• ser = to be, for identity, permanent characteristics, definitions

So:

• O churrasqueiro está perto da churrasqueira. = The grill cook is near the barbecue grill.
• O churrasqueiro é simpático. = The grill cook is nice.
• Ele é churrasqueiro. = He is a grill cook.

Here, the sentence is saying where the person is, so está is the natural choice.

Churrasqueiro usually refers to a person associated with making churrasco, especially the person who grills the meat.

Depending on context, it can mean things like:

• grill cook
• barbecue cook
• the person in charge of the barbecue

In Brazil, this word often suggests someone who is actively grilling meat, not just any cook.

Churrasqueira is the grill, barbecue pit, or barbecue structure where the meat is cooked.

In Brazilian Portuguese, it can refer to:

• a built-in barbecue area
• a grill appliance
• the place where the barbecue is being prepared

So in this sentence:

• churrasqueiro = the person
• churrasqueira = the grill / barbecue structure

Because both words are built from churrasco.

Portuguese often creates related words with endings like these:

• -eiro can refer to a person associated with something
• -eira can refer to an object, place, or something associated with that root

So:

• churrasco = barbecue
• churrasqueiro = barbecue person / grill cook
• churrasqueira = barbecue grill / barbecue place

This kind of word family is very common in Portuguese.

Because da is a contraction:

• de + a = da

The expression perto normally comes with de:

• perto de = near, close to

So:

• perto de a churrasqueira becomes perto da churrasqueira

This contraction is required in normal Portuguese.

Other similar contractions are:

• de + o = do
• em + a = na
• em + o = no

Portuguese uses definite articles much more often than English.

So O churrasqueiro literally means the grill cook. In English, we might sometimes say just the grill cook, the guy at the grill, or even omit an article in other contexts, but Portuguese tends to keep it.

Using the article here sounds natural and complete.

Because churrasqueira is being treated as a specific noun, and Portuguese often uses articles before nouns in cases where English may or may not.

Since da = de + a, the a is the feminine singular definite article:

• a churrasqueira = the grill
• da churrasqueira = of the grill / near the grill, after perto de

So the article is part of normal Portuguese structure.

Perto means near or close. It does not necessarily mean immediately beside something.

So:

• perto da churrasqueira = near the grill / close to the grill

If you want to say something more like right next to, Portuguese might use other expressions depending on context, such as:

• ao lado da churrasqueira = next to the grill

So perto suggests proximity, but not necessarily direct side-by-side position.

Yes. Perto de is very common and works with many kinds of nouns.

Examples:

• perto de casa = near home
• perto da praia = near the beach
• perto do restaurante = near the restaurant
• perto de mim = near me

So in this sentence, perto da churrasqueira follows a very common pattern.

The accent mark in está shows that the stress falls on the last syllable:

• es-TÁ

The written accent helps distinguish pronunciation and spelling.

In Brazilian Portuguese, it is roughly pronounced like:

• es-TAH

The final vowel is open and stressed.

This is just the normal present-tense form of estar for he/she/it is or you are.

Yes, churrasqueiro is masculine singular.

If the person is a woman, you would usually say:

• A churrasqueira? No, that would usually mean the grill, so that does not work here.
• A churrasqueira = the female grill cook / barbecue cook

So:

• O churrasqueiro está perto da churrasqueira. = The male grill cook is near the grill.
• A churrasqueira está perto da churrasqueira. = The female grill cook is near the grill.

This is a useful example because churrasqueira and churrasqueira look very close, but they mean different things.

Yes, but the original order is the most neutral and natural.

Standard order:

• O churrasqueiro está perto da churrasqueira.

You could also say:

• Perto da churrasqueira está o churrasqueiro.

This sounds more marked or stylistic, as if emphasizing the location first.

For everyday speech, the original version is the best one to learn first.

Usually, no. In normal Portuguese, that sounds incomplete or unnatural in most contexts.

Portuguese generally prefers:

• O churrasqueiro...
• A cozinheira...
• O garçom...

Leaving out the article might happen in headlines, labels, or very special contexts, but not in ordinary speech. So for normal usage, keep O.
