A hóspede quer pagar duas diárias, porque vai ficar no hotel até segunda-feira.

Hóspede can refer to either a male or a female guest. The noun itself stays the same, and the article shows the gender:

• o hóspede = a male guest
• a hóspede = a female guest

So in this sentence, a hóspede tells you the guest is female.

Because diária is a feminine noun.

In Portuguese, two changes form depending on gender:

• dois for masculine nouns
• duas for feminine nouns

So:

• dois quartos = two rooms
• duas diárias = two daily hotel charges / two nights

In hotel language, diária is not just a literal day. It means a daily hotel rate or one night’s stay charge.

So duas diárias means the guest wants to pay for two hotel nights / two daily rates.

This is a very common hospitality word in Brazilian Portuguese.

Vai ficar is the very common spoken Brazilian Portuguese way to talk about the future.

It is formed with:

• ir in the present tense + infinitive

So:

• vai ficar = will stay / is going to stay

You could also say ficará, but that sounds more formal or written. In everyday Brazilian Portuguese, vai ficar is usually more natural.

Here, até means until.

So até segunda-feira means until Monday.

It marks the end point in time.

In time expressions like this, Portuguese often uses the day of the week without an article after até:

• até segunda-feira
• até terça-feira

That is the normal way to say until Monday, until Tuesday, and so on.

Because that is the standard spelling in Portuguese.

The weekdays from Monday to Friday are written like this:

• segunda-feira
• terça-feira
• quarta-feira
• quinta-feira
• sexta-feira

In everyday speech, Brazilians often shorten them:

• segunda
• terça
• quarta

But the full form with the hyphen is completely correct.

In Portuguese, days of the week are normally written in lowercase, not with capital letters.

So:

• segunda-feira
• janeiro
• domingo

This is different from English, where Monday is capitalized.

Because here it introduces a reason, so it means because.

• porque = because

Portuguese also has por que, por quê, and porquê, but they are used in other situations.

In this sentence, the guest wants to pay two daily rates because she is going to stay until Monday, so porque is the correct form.

No is a contraction of:

• em + o = no

So:

• no hotel = in the hotel / at the hotel

This happens very often in Portuguese:

• na recepção = em + a
• do quarto = de + o
• da reserva = de + a

Usually yes: it means Monday is the limit point.

In a hotel context, vai ficar no hotel até segunda-feira normally means the guest is staying up to Monday, often leaving on Monday.

The exact checkout time depends on the hotel, but grammatically segunda-feira is the endpoint.

Grammatically, quer is the present tense of querer.

• quer pagar = wants to pay

In context, it often sounds like a current intention: the guest wants to pay now or wants to arrange payment.

So it is simple present, but in real conversation it can refer to an immediate situation.
