O comando está claro.

Comando is a masculine singular noun, so it normally takes the definite article o when you are talking about the command in a specific context.

• o comando = the command
• um comando = a command

In Portuguese, articles are used more often than in English, so leaving out o would usually sound incomplete or unnatural here.

Comando usually means command, but the exact sense depends on context. In Brazilian Portuguese, it can refer to things like:

• a computer command
• a military command
• an instruction or directive
• a control mechanism in some contexts

So in this sentence, it means the command or the instruction, depending on the situation.

Portuguese has two main verbs for to be: ser and estar.

Here, está is used because claro is describing a current state or condition: the command is clear right now.

• está claro = it is clear / it’s clear
• é claro often means it is obvious, of course, or describes something in a more general way

So:

• O comando está claro. = The command is clear.
• É claro. = Of course. / It’s obvious.

Está is the 3rd person singular present tense of estar.

The full present-tense forms of estar are:

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

Since o comando is singular, the verb is está.

The acute accent in está shows which syllable is stressed and helps distinguish it from similar-looking words.

• está is pronounced with stress on the final syllable: es-TÁ

The accent is an important part of the spelling, so you should always write it.

Because claro is an adjective describing comando, and adjectives usually agree with the noun in gender and number.

Since comando is:

• masculine
• singular

the adjective is also:

• claro

Examples:

• o comando está claro = masculine singular
• a instrução está clara = feminine singular
• os comandos estão claros = masculine plural
• as instruções estão claras = feminine plural

No. Comando is a masculine noun, so you need:

• o comando
• claro

not:

• a comando
• clara

Those feminine forms would only work with a feminine noun, such as a instrução.

The most neutral and natural order is:

• O comando está claro.

You may sometimes hear or read a different order for emphasis or style, but Está claro o comando is not the normal everyday way to say this exact idea. It sounds marked and less natural in most contexts.

For a learner, the standard pattern subject + verb + adjective is the safest choice here.

A rough pronunciation guide is:

oo koh-MAHN-doh es-TAH KLAH-roh

A few helpful notes:

• comando has stress on man: co-MAN-do
• está has stress on the last syllable: es-TÁ
• claro usually sounds like KLA-ro
• In natural Brazilian speech, the initial o article may sound more like a quick u

So you may hear something close to:

u co-MAN-du es-TA KLA-ru

depending on the speaker.

Yes. Claro is a very common word in Portuguese.

As an adjective, it can mean:

• clear
• light-colored
• obvious, depending on context

It also appears in expressions like:

• Claro! = Of course!
• É claro. = Of course. / It’s obvious.

But in O comando está claro, it simply means clear.

Yes, it is grammatical and natural, especially in contexts involving instructions, systems, procedures, or formal communication.

Depending on the situation, Brazilians might also say things like:

• A instrução está clara.
• A ordem está clara.
• Ficou claro o comando.
• O comando ficou claro.

But O comando está claro is perfectly correct.

You can make it negative by adding não before the verb:

• O comando não está claro. = The command is not clear.

You can turn it into a yes/no question mainly with intonation in speech:

• O comando está claro? = Is the command clear?

In writing, just add a question mark. Portuguese does not usually use auxiliary verbs like English do or inversion like Is the command....

The plural is:

• Os comandos estão claros.

Everything changes to match the plural:

• o → os
• comando → comandos
• está → estão
• claro → claros

This agreement is very important in Portuguese.
