A reciclagem é importante.

Because reciclagem is a feminine singular noun, so it takes the feminine singular definite article a.

In Portuguese, it is very common to use the definite article with nouns when talking about something in a general sense. So A reciclagem é importante sounds natural for Recycling is important.

English often leaves out the article in this kind of sentence, but Portuguese often keeps it.

You mainly know it because native usage is a reciclagem, not o reciclagem.

The ending -agem is very often feminine in Portuguese, so many nouns with this ending are feminine:

• a viagem
• a mensagem
• a paisagem
• a reciclagem

So reciclagem is feminine singular.

É is from the verb ser, which is usually used for general facts, definitions, and more permanent characteristics.

Here, the sentence is expressing a general truth: Recycling is important. So ser is the right choice.

Using estar would usually suggest a temporary state or a specific situation, which is not the main idea here.

• A reciclagem é importante. = a general fact
• A reciclagem está importante no debate político. = recycling has become important in the political debate

The accent is important because é is the verb form is, from ser.

Without the accent, e means and.

So:

• é = is
• e = and

The accent also helps show the pronunciation: é has an open vowel sound.

Because importante is an adjective with the same form for both masculine and feminine in the singular.

So you get:

• o livro importante
• a reciclagem importante

It only changes in the plural:

• o livro importante
• os livros importantes
• a reciclagem importante
• as ideias importantes

So in this sentence, importante matches the singular subject, but not with a different masculine/feminine ending.

You might see that in headlines, slogans, notes, or very informal shortened style, but in normal standard Brazilian Portuguese, A reciclagem é importante is the most natural version.

Leaving out the article can sound abrupt or less standard in everyday speech.

So for a learner, it is safest to use:

• A reciclagem é importante.

No. Reciclagem is a noun.

The verb is reciclar, meaning to recycle.

So:

• reciclar = to recycle
• reciclagem = recycling / the process of recycling

In this sentence, reciclagem is the subject of the sentence.

The structure is:

Subject + verb + adjective

• A reciclagem = subject
• é = verb
• importante = adjective

This is a very common and basic Portuguese sentence pattern.

Yes, but the normal, neutral order is:

• A reciclagem é importante.

You could say:

• Importante é a reciclagem.

But that sounds much more emphatic, literary, or contrastive, like What is important is recycling.

For everyday neutral Portuguese, keep the original order.

A simple English-friendly approximation is:

ah heh-see-klah-ZHEM eh eem-por-TAHN-chee

A few useful notes:

• r at the start of reciclagem is often pronounced like an English h in many Brazilian accents.
• gem in reciclagem sounds like zhem with a nasal ending.
• é sounds like eh.
• The final te in importante often sounds like chee in many parts of Brazil.

Pronunciation varies by region, but that approximation will help you get close.

In this sentence, it normally means recycling in general.

Even though Portuguese uses the definite article a, it can still refer to something as a general concept.

So:

• A reciclagem é importante. = recycling, as a general idea, is important

This is one of the places where Portuguese uses an article but English often does not.

The plural would be:

As reciclagens são importantes.

But this is much less common if you mean the general concept of recycling. The singular is more natural for the broad idea:

• A reciclagem é importante.

The plural would usually be used only if you were talking about different types, systems, or instances of recycling.
