Todos veem a beleza do vale.

Here todos means everyone or all people.

Portuguese often uses todos by itself to mean all of them or everyone, depending on context. In this sentence, it refers to people in general.

A very common mistake for English speakers is to confuse todos with tudo:

• todos = everyone / all people / all of them
• tudo = everything

So Todos veem a beleza do vale talks about people seeing it, not about everything seeing it.

Because todos is the masculine plural form.

In Portuguese, the masculine plural is used for:

• a group of men
• a mixed group of men and women
• a group whose gender is unspecified

If you were talking about a group made up only of women, you would say todas.

So:

• Todos veem a beleza do vale = everyone / all of them see the beauty of the valley
• Todas veem a beleza do vale = all the women / girls see the beauty of the valley

veem is the 3rd person plural present indicative of the verb ver, meaning to see.

So the verb matches todos:

• ele / ela vê = he / she sees
• eles / elas veem = they see

That is why the sentence uses veem and not vê.

Both spellings may appear, depending on what you have learned or what materials you are using.

• vêem = older spelling
• veem = current standard spelling after the spelling reform

So in modern standard Portuguese, veem is the expected spelling.

This is easy to confuse with vêm, which is different:

• veem = they see, from ver
• vêm = they come, from vir

So:

• Todos veem = everyone sees
• Todos vêm = everyone comes

In European Portuguese, veem is pronounced as a form of ver with a plural ending, and it is usually heard as having a clear vowel sequence, roughly like VEH-em or VEE-em, depending on accent and speaking style.

The important point for a learner is:

• it is not pronounced like English veem
• it is the plural form of vê

If you already know:

• vê = sees

then veem is the corresponding they see form.

That a is the feminine singular definite article, meaning the.

So:

• a beleza = the beauty

Portuguese uses definite articles more often than English does, including with abstract nouns. In this sentence, a beleza sounds natural and definite: it refers to the beauty of the valley.

If you removed the article and said veem beleza do vale, it would sound unnatural in standard Portuguese.

Because de + o contracts to do.

So:

• de = of
• o = the
• do = of the

The noun beleza is followed by de to show what the beauty belongs to:

• a beleza do vale = the beauty of the valley

Also, vale is a masculine noun, so it takes o, not a:

• o vale = the valley
• do vale = of the valley

Usually not if you want to keep the meaning everyone.

Portuguese often allows the subject to be omitted, but if you remove todos, the sentence changes:

• Todos veem a beleza do vale = everyone sees the beauty of the valley
• Veem a beleza do vale = they see the beauty of the valley

Without todos, the sentence no longer clearly means everyone. It just means they see it, and the subject would have to come from context.

Yes, it is grammatical and natural.

That said, in everyday European Portuguese, people very often use toda a gente to mean everyone:

• Toda a gente vê a beleza do vale.

Notice that toda a gente takes a singular verb:

• Toda a gente vê
• not Toda a gente veem

So both are possible, but toda a gente is extremely common in speech.

Yes, but the original order is the most neutral and straightforward:

• Todos veem a beleza do vale.

That is a normal subject + verb + object order.

You could change the order for emphasis or style, for example:

• A beleza do vale todos veem.

But that sounds more marked, literary, or emphatic. For a learner, the original version is the best basic pattern to remember.
