A cor daquela blusa é bonita.

In Portuguese, it is very common to use the definite article with nouns when speaking in a general or specific way.

So a cor means the color.

In this sentence, the speaker is talking about the specific color of a specific blouse, so a cor sounds natural. Leaving the article out would usually sound incomplete or unnatural here.

Daquela is a contraction of:

• de = of
• aquela = that

So:

• de + aquela = daquela

This is very common in Portuguese. Since the sentence means the color of that blouse, Portuguese uses de to show possession or relationship.

Similar contractions:

• de + o = do
• de + a = da
• de + este = deste
• de + essa = dessa

Portuguese usually does not use the English-style ’s possessive structure.

Instead, it normally uses:

• noun + de + noun

So:

• the color of that blouse → a cor daquela blusa

This structure is much more natural in Portuguese than trying to copy the English possessive pattern.

Aquela is a feminine singular demonstrative adjective meaning that.

It agrees with blusa, which is feminine singular.

Basic forms:

• este / esta = this
• esse / essa = that
• aquele / aquela = that over there / that one

In everyday Brazilian Portuguese, the distinction between esse/essa and aquele/aquela is often less strict than in grammar books, but aquela blusa is perfectly natural for that blouse.

Because blusa is a feminine noun.

In Portuguese, demonstratives must agree with the noun in gender and number:

• aquele = masculine singular
• aquela = feminine singular
• aqueles = masculine plural
• aquelas = feminine plural

Since blusa is feminine singular, the correct form is aquela.

Because bonita agrees with cor, which is feminine.

• cor = feminine noun
• so the adjective must also be feminine singular: bonita

This is an important point: bonita describes cor, not directly blusa.

So the structure is:

• A cor → subject
• é bonita → description of the subject

Even though blusa is also feminine, the adjective here is grammatically linked to cor.

Grammatically, it describes the color.

The subject of the sentence is A cor daquela blusa = The color of that blouse.

So é bonita means is beautiful / is pretty, referring to the color.

If you wanted to say the blouse is pretty, you would say:

• Aquela blusa é bonita.

That means That blouse is pretty.

Portuguese often uses two verbs for to be:

• ser → é
• estar → está

Here, é bonita uses ser because the sentence describes a characteristic or quality of the color.

So:

• é bonita = it is beautiful / pretty as a description

Using está bonita would suggest a more temporary or situational state, which is less natural when talking about a color itself.

The structure is:

• A cor daquela blusa = the color of that blouse
• é = is
• bonita = beautiful / pretty

So the pattern is:

• subject + verb + adjective

More literally:

• The color of that blouse is beautiful.

This is a very common Portuguese sentence pattern.

Cor is a feminine noun even though it does not end in -a.

That is normal in Portuguese: grammatical gender does not always match the final letter.

Examples:

• a cor = the color
• a flor = the flower
• a dor = the pain

So you simply have to learn its gender as part of the word: a cor.

In Brazilian Portuguese, cor is pronounced roughly like kohr, with a sound similar to English core, though the Portuguese r may vary depending on accent.

Yes. That would mean The color of the blouse is pretty.

The difference is:

• da blusa = of the blouse
• daquela blusa = of that blouse

So daquela adds the idea of that specific blouse.

Both are correct; the choice depends on whether you want to point out which blouse you mean.

It can be either, depending on context.

Bonito/bonita is a very common adjective that can mean:

• beautiful
• pretty
• nice
• good-looking

When talking about a color, English might naturally say:

• The color of that blouse is beautiful or
• The color of that blouse is pretty

Both are reasonable. The exact best translation depends on tone and context.
