El cambio de turno puede causar horas extra.

Cambio de turno is the natural fixed expression for shift change in Spanish.

Spanish often uses noun + de + noun where English uses one noun to modify another:

• cambio de turno = shift change
• jefe de oficina = office manager
• zapatos de deporte = sports shoes

Del turno would sound more specific, as if you meant the change of the shift of a particular one, which is not the usual way to express this general idea.

Here, turno means work shift.

The word turno can mean different things depending on context, such as:

• shift at work
• turn in a queue or game
• appointment slot

In this sentence, because of cambio de turno and horas extra, the work-related meaning is the one intended.

Spanish uses the definite article el / la / los / las more often than English.

Here, El cambio de turno is the subject of the sentence. Spanish naturally says El cambio de turno puede... where English might sometimes just say Shift change can... without the.

So el is not unusual here; it makes the noun phrase sound complete and natural.

Because the subject is singular: El cambio de turno.

The main noun of that subject is cambio, which is singular, so the verb must also be singular:

• El cambio de turno puede...
• Los cambios de turno pueden...

Even though horas is plural later in the sentence, that is the object, not the subject, so it does not affect the verb form.

Here, puede means can in the sense of is able to or is capable of.

It is not about permission. The sentence is saying that a shift change can cause overtime, meaning it is a possible result.

So in this context:

• puede causar = can cause / may cause

Both English translations are possible, but the idea is possibility, not permission.

Because horas extra is being mentioned in a general, indefinite way.

After verbs like causar, Spanish often leaves out the article when talking about something nonspecific:

• causar problemas
• causar retrasos
• causar horas extra

If you were talking about specific overtime hours already known in the conversation, you could use an article:

• puede causar las horas extra previstas

But in the original sentence, the no-article version is the most natural.

In this expression, extra often behaves as an invariable adjective after the noun, so horas extra is very common and natural, especially in workplace language.

You may also hear horas extras, and it is widely understood. But horas extra is very common in Spain and is a standard way to say overtime hours.

Compare:

• una hora extra
• dos horas extra

So learners should be comfortable with extra staying the same here.

Yes. Causar is correct and natural, especially in neutral or formal Spanish.

It means to cause and is common in reports, policies, workplace writing, and more formal speech.

Other verbs are possible depending on style:

• provocar = also to cause, sometimes a bit stronger
• generar = to generate, common in business or technical contexts
• ocasionar = to cause, fairly formal

But puede causar horas extra is perfectly good Spanish.

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

• El cambio de turno puede causar horas extra.

Spanish usually prefers subject + verb + object in straightforward statements.

You could change the order for emphasis, but it would sound less neutral:

• Horas extra puede causar el cambio de turno.

That version is grammatically possible, but it is not the most natural choice for ordinary speech or writing here.

A simple pronunciation guide is:

el KAM-byoh deh TOOR-noh PWEH-deh kaw-SAR OH-ras EKS-tra

A few useful details:

• cambio: the bio sounds roughly like byo
• turno: the u is a clear oo sound
• puede: starts with pweh-
• h in horas is silent
• r in horas is a light Spanish r, not a strong English r

In Spain, the rhythm is usually smooth and fairly even: El cambio de turno puede causar horas extra.
