No contesta al móvil; tendrá clase todavía.

Both contestar and responder can mean to answer, but in Spain contestar al móvil / al teléfono is very natural for answering the phone.

So:

• No contesta al móvil = He/She isn’t answering their mobile phone.
• No responde often feels broader, like isn’t responding in general, not necessarily specifically by picking up the phone.

In this sentence, contestar fits the phone context especially well.

Al is the contraction of a + el.

Here, móvil is masculine, so:

• a el móvil → al móvil

With contestar, Spanish often uses a before the thing or person being answered:

• contestar al teléfono
• contestar al móvil
• contestar a una pregunta

So No contesta al móvil literally means something like He/She doesn’t answer the mobile phone.

In Spain, móvil means mobile phone / cell phone.

So:

• Spain: móvil
• Latin America often prefers: celular

A learner of Spain Spanish should get used to móvil, because it is extremely common.

Spanish often drops subject pronouns because the verb ending already shows the person.

Here:

• contesta = he/she answers
• tendrá = he/she will have or, in this case, he/she probably has

So Spanish does not need él or ella unless the speaker wants emphasis or contrast.

This is very normal:

• No contesta al móvil
• Tendrá clase todavía

English usually needs he/she, but Spanish often does not.

This is one of the most important things in the sentence.

The future tense in Spanish is not only used for real future time. It can also express guessing, probability, or assumption about the present.

So:

• Tendrá clase todavía does not necessarily mean He/She will have class later
• It often means He/She probably still has class

This is called the future of probability or future of conjecture.

Similar examples:

• Estará en casa = He/She is probably at home.
• Serán las cinco = It’s probably around five o’clock.
• Tendrá sueño = He/She is probably sleepy.

Grammatically, tendrá clase todavía could look like a normal future, but in this context it is much more natural to understand it as a guess about the present:

• He/She probably still has class

Why? Because it explains the first part:

• No contesta al móvil → He/She isn’t answering the phone.
• Tendrá clase todavía → They probably still have class.

So the second clause gives a likely reason for the first one.

Here tener clase means to have class / to be in class / to have a lesson.

So tendrá clase means:

• he/she probably has class
• he/she is probably still in class

It usually refers to school, university, or some lesson.

Note that clase is singular here because Spanish often uses tener clase as a general expression, not necessarily focusing on the number of lessons.

Todavía means still here.

So:

• tendrá clase todavía = he/she probably still has class

It shows that the class has not finished yet.

In many contexts, todavía and aún can both mean still:

• Todavía está en clase
• Aún está en clase

Both are correct. Todavía is very common and natural.

Yes. Spanish word order is flexible.

These are possible:

• Tendrá clase todavía
• Todavía tendrá clase

Both can work. The version in your sentence sounds natural and conversational.

Placing todavía first can give it a bit more emphasis:

• Todavía tendrá clase = He/She probably still has class.

The semicolon links two closely related ideas:

• No contesta al móvil
• tendrá clase todavía

The second clause explains the first one.

In everyday writing, many people might also use:

• a full stop: No contesta al móvil. Tendrá clase todavía.
• a comma in informal writing
• or a connector: No contesta al móvil; todavía tendrá clase.

The semicolon simply shows a strong connection between the two parts without making them separate sentences.

Not exactly, though they can be similar in context.

• No contesta al móvil = He/She doesn’t answer the phone / isn’t answering the phone.
• No está contestando al móvil = He/She is not answering the phone right now.

Spanish often uses the simple present where English might prefer a present continuous form. So no contesta can already sound perfectly natural for isn’t answering in this situation.

You might hear it, and people would understand it, but No contesta al móvil sounds more idiomatic for not answering the phone.

A more natural comparison would be:

• No contesta al móvil = He/She isn’t answering the mobile.
• No responde a mis mensajes = He/She isn’t replying to my messages.

So contestar is especially common for phones and direct answering, while responder is often broader.

It is neutral and very natural in everyday Spanish.

Nothing in it is especially formal or especially slangy:

• móvil is standard in Spain
• contesta is normal everyday usage
• tendrá clase todavía is a standard, natural way to make a guess

So this is a good real-life sentence to learn.
