Eu li a apólice hoje.

Li is the simple past form of the verb ler (to read).

So:

• ler = to read
• eu li = I read

This means the action was completed in the past: I read the policy today.

A useful comparison:

• eu leio = I read / I am reading
• eu li = I read / I did read

Unlike English, Portuguese clearly changes the verb form, so li can only mean past.

Yes, you can absolutely say Li a apólice hoje.

In Portuguese, the subject pronoun is often omitted because the verb form already shows who the subject is. Since li clearly means I read, eu is not required.

So both are correct:

• Eu li a apólice hoje.
• Li a apólice hoje.

Including eu can add:

• emphasis
• contrast
• clarity in some contexts

For example:

• Eu li a apólice hoje, mas ele não.
  I read the policy today, but he didn’t.

Because apólice is a feminine noun, so it takes the feminine singular article a (the).

• a apólice = the policy
• uma apólice = a policy

In Portuguese, articles are used more often than in English. If you are talking about a specific policy, a apólice is very natural.

If you said just Li apólice hoje, it would sound incomplete or unnatural in normal Portuguese.

You usually learn the gender together with the noun:

• a apólice

There is no perfect rule that always tells you gender just from the ending, so it is best to memorize nouns with their article.

Even though many feminine nouns end in -a, apólice does not, so this is a good example of why learning the article is important.

Li is pronounced roughly like lee in English.

So:

• li ≈ lee

It is a very short, simple word.

Apólice is pronounced roughly:

ah-POH-lee-see

In Brazilian Portuguese, the stress falls on pó because of the accent mark:

• a-PÓ-li-ce

The accent in apólice shows which syllable is stressed. Without that accent, a learner might guess the stress incorrectly.

Also, in Brazilian Portuguese, the final ce sounds like see.

Hoje means today and tells you when the reading happened.

In Eu li a apólice hoje, it modifies the whole action:

• Eu li = I read
• a apólice = the policy
• hoje = today

So the full idea is: I read the policy today.

Yes. Portuguese allows some flexibility with adverbs like hoje.

These are all natural, though they may sound slightly different in emphasis:

• Eu li a apólice hoje.
• Hoje eu li a apólice.
• Eu hoje li a apólice. (possible, but less neutral)

The most neutral choices are usually:

• Eu li a apólice hoje.
• Hoje eu li a apólice.

Putting hoje first can emphasize today.

In English, read is spelled the same in the present and the past:

• I read every day
• I read it yesterday

But in Portuguese, the forms are different:

• eu leio = I read / I am reading
• eu li = I read

So Portuguese makes the time reference clearer through the verb form itself.

Yes, slightly.

• Li a apólice hoje. = I read the policy today.
• Li uma apólice hoje. = I read a policy today.

Using a suggests a specific, known policy.
Using uma suggests one policy, perhaps not previously identified.

So if you mean a particular document, a apólice is the natural choice.

Yes, it is grammatically normal and natural.

The only thing to note is that apólice is a somewhat formal or specialized word, since it usually refers to an insurance policy or a similar official document. The grammar itself, though, is completely standard everyday Brazilian Portuguese.
