Posso ver o alvo.

Posso is the first-person singular present form of poder, which means to be able to or can.

So:

• poder = to be able to / can
• posso = I can

In Posso ver o alvo, posso means I can.

In Portuguese, the subject pronoun is often omitted when the verb form already makes the subject clear.

Because posso can only mean I can, native speakers usually do not need to say eu.

So both are correct:

• Posso ver o alvo.
• Eu posso ver o alvo.

The version without eu sounds very natural and common.

Because after poder, Portuguese normally uses an infinitive.

So the structure is:

• posso = I can
• ver = see

Together: I can see

This is similar to English, where after can you use the base form:

• I can see
• not I can sees

Portuguese works similarly here:

• Posso ver
• not Posso vejo

O is the masculine singular definite article, meaning the.

So:

• o = the
• alvo = target

Together:

• o alvo = the target

Portuguese uses articles very often, sometimes more often than English does.

Alvo usually means target.

It can be used in a few ways:

• a physical target, such as in shooting or aiming
• a person or thing being targeted
• a figurative target, such as in criticism or an investigation

So in Posso ver o alvo, alvo most naturally means the target.

A simple approximate pronunciation for an English speaker is:

POH-soo veh(r) oo AHL-voo

A few notes:

• posso: stress on the first syllable
• ver: in Brazil, the final r is often pronounced softly, almost like an h sound in many accents
• o by itself is often pronounced more like oo
• alvo: stress on al

Pronunciation varies across Brazil, but this approximation is a helpful start.

Yes, this is the most normal and neutral word order:

• Posso = I can
• ver = see
• o alvo = the target

So:

• Posso ver o alvo. = I can see the target.

Portuguese does allow some flexibility, but this version is the standard, natural order.

Yes, Portuguese can use the same words for a statement or a question. Intonation and punctuation help show the difference.

Compare:

• Posso ver o alvo. = I can see the target.
• Posso ver o alvo? = Can I see the target?

So with a period, it is a statement. With a question mark, it becomes a question.

Yes, but the meaning shifts slightly.

• Posso ver o alvo = I can see the target / I am able to see the target
• Consigo ver o alvo = I manage to see the target / I’m able to make it out

Conseguir often suggests success in managing to do something, sometimes with difficulty.

So:

• posso is the more basic and general can
• consigo can sound more like I’m able to or I manage to

Usually yes, but like see in English, it can have slightly different uses depending on context.

Most commonly:

• ver = to see

But in other contexts it can also be closer to:

• to watch
• to look at
• to check
• to meet, in some expressions

In Posso ver o alvo, the meaning is clearly the basic one: to see.

Yes, it is grammatical and natural.

It is a simple, clear sentence that a Brazilian speaker would understand immediately. Whether it feels common in everyday conversation depends on context, because o alvo is somewhat specific. It sounds especially natural in situations involving:

• aiming
• hunting
• games
• military or police contexts
• figurative targeting

So the grammar is completely natural, and the vocabulary is appropriate when the situation involves a target.
