O cume está coberto de neve.

Cume means summit, peak, or top of a mountain.

For a learner, it is good to know that:

• cume is correct and natural
• it can sound a little more literary or descriptive than very everyday words like topo
• in mountain contexts, pico, cume, and topo can overlap, but they are not always identical in tone

So O cume está coberto de neve is a perfectly good sentence, especially in descriptive or written language.

O means the and is the masculine singular definite article.

It is used here because cume is a masculine singular noun:

• o cume = the summit

Portuguese uses definite articles very often, just as English does in this kind of sentence. Here it refers to a specific summit, not just any summit in general.

Cume is masculine, which is why the sentence has:

• o cume
• coberto rather than coberta

This is important because adjectives in Portuguese usually agree with the noun they describe.

So:

• o cume está coberto
• if the noun were feminine, it would be coberta

There is not always a simple rule based on the ending, so this is something you often learn together with the article: o cume.

Portuguese usually uses estar for a state or condition, especially one seen as temporary, changeable, or the result of something.

So:

• está coberto de neve = is covered in snow

This describes the summit’s current condition.

If you used é coberto de neve, it would sound more like a general characteristic or something habitual, and in this sentence that is less natural.

A useful way to think about it:

• ser = what something is
• estar = how something is / is situated / is at the moment

Coberto is the past participle of cobrir = to cover.

Here it works like an adjective and agrees with cume:

• cume = masculine singular
• so: coberto

Compare:

• o cume está coberto
• a montanha está coberta
• os cumes estão cobertos
• as montanhas estão cobertas

So the ending changes to match the noun.

The normal Portuguese pattern is coberto de when you mean covered with / covered in a substance or material.

So:

• coberto de neve
• coberto de pó
• coberto de água
• coberto de areia

Using com is much less natural here. A Portuguese learner should remember coberto de as the standard expression.

In coberto de neve, neve is being used in a general, material-like sense: covered in snow.

That is why there is no article:

• de neve = with snow / in snow, generally

If you added an article, it would usually point to something more specific:

• da neve = of the snow, meaning some specific snow already identified in context

In this sentence, the general form de neve is the natural one.

In European Portuguese, the pronunciation is approximately:

• u KOO-m(ə) shtah ku-BEHR-tu d(ɨ) NEV(ə)

A few useful points:

• O often sounds like u
• está often sounds close to shtá
• unstressed e is often reduced, especially in European Portuguese
• de is often a very weak sound, something like dɨ

So the sentence may sound more compressed than its spelling suggests.

Yes. Topo is another common word for top or summit.

But there can be a slight difference in feel:

• cume = summit/peak, often more specifically mountain-related
• topo = top, broader and more everyday

So both can work, but cume sounds especially suitable for a mountain summit.

Yes, but the meaning changes slightly.

• O cume está coberto de neve = the summit is covered in snow
• A montanha está coberta de neve = the mountain is covered in snow

The second sentence refers to the whole mountain, not just the top.

Also notice the agreement change:

• a montanha is feminine
• so it becomes coberta

The plural would be:

• Os cumes estão cobertos de neve.

Changes:

• o → os
• cume → cumes
• está → estão
• coberto → cobertos

Everything has to agree with the plural noun.

No. Portuguese de often corresponds to English with, in, or sometimes no direct word-for-word equivalent.

So although the Portuguese says coberto de neve, the natural English translation is:

• The summit is covered in snow
• The summit is covered with snow

This is a good example of why translating prepositions word for word often does not work well between Portuguese and English.
