No café da manhã, minha filha prefere leite, mas eu prefiro café forte.

No is a contraction of em + o, which becomes no.

So:

• em = in / at / on
• o = the
• no = in the / at the

In this sentence, No café da manhã means at breakfast or literally in the breakfast time/context.

Related forms:

• na = em + a
• nos = em + os
• nas = em + as

In Brazilian Portuguese, café da manhã is the normal expression for breakfast.

Literally, it means something like morning coffee:

• café = coffee
• da = de + a = of the
• manhã = morning

Even though it literally mentions coffee, the whole phrase just means breakfast. It is a fixed expression, so learners should treat it as one vocabulary item.

Da is a contraction of de + a.

So:

• de = of / from
• a = the
• da = of the

That is why café da manhã literally looks like coffee of the morning.

This kind of contraction is extremely common in Portuguese:

• do = de + o
• da = de + a
• dos = de + os
• das = de + as

Both are possible.

In Brazilian Portuguese, possessives like meu/minha/seu/sua can appear:

• with an article: a minha filha
• without an article: minha filha

So both of these can sound natural:

• Minha filha prefere leite
• A minha filha prefere leite

In Brazil, leaving out the article before a possessive is very common, especially in everyday speech. A learner will hear both patterns.

Because the verb preferir changes according to the subject.

Here it is in the present tense:

• eu prefiro = I prefer
• você prefere = you prefer
• ele/ela prefere = he/she prefers
• nós preferimos = we prefer
• vocês preferem = you all prefer
• eles/elas preferem = they prefer

So:

• minha filha prefere = my daughter prefers
• eu prefiro = I prefer

This is a normal Portuguese verb conjugation pattern.

No, you do not have to use it, because Portuguese often drops subject pronouns when the verb already makes the subject clear.

So these are both possible:

• ..., mas eu prefiro café forte.
• ..., mas prefiro café forte.

However, eu is very natural here because it adds contrast:

• my daughter prefers one thing,
• I prefer another.

So mas eu prefiro sounds especially clear and contrastive.

In Portuguese, when talking about food or drink in a general sense, it is very common to omit the article.

So:

• prefere leite = prefers milk
• prefiro café forte = I prefer strong coffee

This sounds natural when you mean the substance generally, not a specific serving.

You could sometimes hear articles in other contexts, but here the zero-article version is perfectly normal and very common.

In Portuguese, adjectives usually come after the noun.

So:

• café forte = strong coffee
• leite frio = cold milk
• casa grande = big house

Putting the adjective before the noun is much less common and often changes the tone, emphasis, or style. Forte café would sound unusual in normal conversation.

So café forte is the expected, natural order.

It can absolutely describe coffee.

In Portuguese, forte is commonly used for:

• physically strong people
• intense smells, flavors, sounds, etc.
• strong coffee

So café forte means coffee with a strong taste, not weak coffee.

This is very idiomatic and natural in Brazilian Portuguese.

The comma separates the introductory time expression from the rest of the sentence.

So the structure is:

• No café da manhã, = at breakfast
• minha filha prefere leite, mas eu prefiro café forte.

This comma is helpful and natural in writing, especially when a sentence begins with a time phrase. You may also see short introductory phrases without commas in casual writing, but this comma is standard and clear.

In this sentence, it most naturally means at breakfast or during breakfast.

It sets the context:

• At breakfast, my daughter prefers milk, but I prefer strong coffee.

Depending on context, English might also translate it as for breakfast, but grammatically the Portuguese phrase is framing the situation in time rather than directly saying what someone eats as a meal choice.

Yes. In this sentence, mas simply means but.

It connects two contrasting ideas:

• minha filha prefere leite
• eu prefiro café forte

So mas marks the contrast between the daughter's preference and the speaker's preference.

Filha is often tricky for English speakers because of lh.

In Brazilian Portuguese:

• lh represents a sound similar to the lli in million for many English speakers, though it is not exactly the same.
• filha sounds roughly like FEE-lya.

A simple approximation:

• fi = fee
• lha = lya

So: FEE-lya

This same lh sound appears in words like:

• mulher
• trabalho
• filho

Yes, Portuguese allows some flexibility.

For example, you could also say:

• Minha filha prefere leite no café da manhã, mas eu prefiro café forte.

That is still understandable, but it slightly changes the focus. The original sentence begins with No café da manhã, which immediately sets the scene: this is about breakfast.

So the original version is very natural if the speaker wants to highlight the time/context first.

Yes. The verbs prefere and prefiro are in the present tense.

In a sentence like this, the present tense usually describes a general preference or habitual situation:

• my daughter tends to prefer milk
• I tend to prefer strong coffee

It does not have to mean only this one breakfast. It usually sounds like a general fact or usual preference unless the context says otherwise.
