Ele parece cansado hoje.

Yes. Portuguese often allows the subject pronoun to be omitted, because the verb form usually shows who the subject is.

So Ele parece cansado hoje can often be shortened to Parece cansado hoje if the context already makes it clear who you mean.

However, ele is still commonly used:

• for clarity
• for emphasis
• when you are introducing a new subject
• when there could be confusion

So both are possible, but ele is perfectly natural.

Parece is the 3rd person singular form of the verb parecer, which usually means:

• to seem
• to appear

In this sentence, it works like English seems.

Some forms of parecer:

• eu pareço = I seem
• você/ele/ela parece = you/he/she seems
• nós parecemos = we seem
• eles/elas parecem = they seem

So parece matches ele.

Because adjectives in Portuguese usually agree with the gender and number of the noun or pronoun they describe.

Here, ele is masculine singular, so:

• ele parece cansado

If the subject were feminine:

• ela parece cansada

If plural:

• eles parecem cansados
• elas parecem cansadas

So cansado changes to match the subject.

In this sentence, it functions as an adjective.

Even though cansado comes from the verb cansar and looks like a past participle, here it describes a state or condition: tired.

That is very common in Portuguese:

• ele está cansado
• ele parece cansado
• ele ficou cansado

In all of these, cansado behaves like an adjective.

Because parecer itself works as a linking verb, just like English to seem.

In English, you say:

• He seems tired

You do not say:

• He seems is tired

Portuguese works the same way:

• Ele parece cansado

So parece directly connects the subject to the description.

The difference is similar to English:

• Ele parece cansado hoje = he seems tired today

  • This is an observation or impression.
  • You are not fully stating it as a fact.

• Ele está cansado hoje = he is tired today

  • This sounds more direct and certain.

So parece is softer and more tentative than está.

Yes, hoje is flexible.

All of these are possible:

• Ele parece cansado hoje
• Hoje ele parece cansado
• Ele hoje parece cansado

The most neutral and common version here is:

• Ele parece cansado hoje

Putting hoje first can give it a little more emphasis:

• Hoje ele parece cansado = Today, he seems tired.

Yes, you can.

• Ele parece cansado hoje = more direct and natural in everyday speech
• Ele parece estar cansado hoje = slightly more explicit, sometimes a bit more formal or careful

Both are correct. In normal conversation, the shorter version is often preferred.

In Brazilian Portuguese, parece is commonly pronounced roughly like:

pah-REH-see

More exactly:

• pa = light, unstressed
• RE = stressed syllable
• ce = often sounds like see in Brazil

So the stress is on the middle syllable:

• pa-RE-ce

That is the normal pattern with linking verbs in Portuguese.

With verbs like:

• ser
• estar
• parecer
• ficar

the adjective usually comes after the verb:

• Ele é alto
• Ela está feliz
• Ele parece cansado
• Nós ficamos prontos

So parece cansado is the expected structure.

Yes, depending on context.

Parecer often means:

• to seem
• to appear
• sometimes to look in the sense of giving an impression

So Ele parece cansado hoje could correspond to English ideas like:

• he seems tired today
• he looks tired today

But the core idea is giving the impression of being tired.

Yes, absolutely. It is natural and common.

Brazilians often use parecer + adjective to describe impressions:

• Ela parece feliz
• Você parece preocupado
• Eles parecem nervosos

So Ele parece cansado hoje sounds normal and everyday.

You would usually change ele to você:

• Você parece cansado hoje if speaking to a man
• Você parece cansada hoje if speaking to a woman

That is because the adjective still agrees with the person’s gender, even though você grammatically uses 3rd person singular verb forms:

• você parece

So:

• Você parece cansado/cansada hoje is the direct version.
