Por la mañana usamos el exprimidor para hacer zumo de naranja.

Por la mañana is the standard Spanish way to say in the morning.

Literally, por can suggest something like during or in the course of, so the full expression is close to during the morning, but in normal English translation it is simply in the morning.

Spanish commonly uses:

• por la mañana = in the morning
• por la tarde = in the afternoon / evening
• por la noche = at night / in the evening

So here, por la mañana usamos... means in the morning we use...

Because in this time expression, Spanish normally uses the article.

So:

• por la mañana
• por la tarde
• por la noche

This is different from English, where we usually say just in the morning without thinking much about the article. In Spanish, the article is part of the normal expression.

Be careful not to confuse:

• la mañana = the morning
• mañana = tomorrow

Usamos is the first person plural form of usar, so it means we use.

In this sentence, it most naturally means we use in the present tense:

• usamos el exprimidor = we use the juicer

One important detail: usamos can also be the preterite form, meaning we used, because the nosotros form looks the same in the present and simple past for many -ar verbs.

So depending on context, usamos could mean:

• we use
• we used

Here, with por la mañana, the most natural reading is the present: In the morning, we use the juicer...

Spanish often uses articles more than English does.

Here, el exprimidor means the juicer. The article is used because the speaker is referring to a specific object, probably the juicer they have at home.

In English, we might sometimes say we use a juicer or we use the juicer, depending on context. In Spanish, el exprimidor sounds very natural if it is understood which juicer is meant.

Also, exprimidor is a masculine noun, so it takes el.

Yes. Exprimidor is a common word in Spain for a device used to squeeze juice from fruit, especially oranges.

It comes from the verb exprimir, which means to squeeze.

So:

• exprimir = to squeeze
• exprimidor = squeezer / juicer

In everyday use in Spain, exprimidor is very natural for an orange juicer or citrus juicer.

Para often means in order to or for when expressing purpose.

When the subject does not change, Spanish normally uses:

• para + infinitive

So:

• para hacer zumo de naranja = to make orange juice / in order to make orange juice

This structure is extremely common:

• Estudio para aprender. = I study to learn.
• Uso un cuchillo para cortar pan. = I use a knife to cut bread.

Here, the purpose of using the juicer is making orange juice:

• usamos el exprimidor para hacer zumo de naranja

Spanish commonly uses hacer in many places where English uses a more specific verb.

So:

• hacer zumo = to make juice
• hacer café = to make coffee
• hacer la cena = to make dinner

There is no everyday direct equivalent used exactly like English to juice in this sentence. Hacer zumo is the normal and natural way to say it.

This is a very important Spain-vs-Latin-America difference.

In Spain:

• zumo is the usual word for juice

In much of Latin America:

• jugo is more common

So for Spain Spanish, zumo de naranja is exactly what you would expect.

Both words are understood by many Spanish speakers, but if you are learning Spanish from Spain, zumo is the best choice here.

Because Spanish often uses de + singular noun to describe the type, material, or flavor of something.

So:

• zumo de naranja = orange juice
• helado de vainilla = vanilla ice cream
• tarta de manzana = apple pie

Even though orange juice is made from oranges, Spanish usually uses the singular noun to name the kind of juice. So zumo de naranja is the normal expression.

Yes, but the meaning changes slightly.

• hacer zumo de naranja = to make orange juice in general
• hacer un zumo de naranja = to make an orange juice / a glass of orange juice / one serving of orange juice

In your sentence, hacer zumo de naranja sounds more general and natural: you use the juicer in order to make orange juice.

If you said hacer un zumo de naranja, it would sound more like one specific juice.

Yes. Both can be used, but there is a small difference.

• por la mañana can mean in the morning, and depending on context it can refer to a routine.
• por las mañanas more clearly suggests in the mornings or every morning / as a habit.

So:

• Por la mañana usamos el exprimidor... = In the morning, we use the juicer...
• Por las mañanas usamos el exprimidor... = In the mornings, we use the juicer...

If you want to emphasize a repeated routine, por las mañanas is often especially clear.

Yes, you could.

Spanish word order is fairly flexible, especially with time expressions.

These are both natural:

• Por la mañana usamos el exprimidor para hacer zumo de naranja.
• Usamos el exprimidor por la mañana para hacer zumo de naranja.

Starting with por la mañana gives a little more emphasis to the time: In the morning...

Putting it later sounds slightly more neutral: We use the juicer in the morning...

Both are correct.
