He tenido que cancelar la videollamada porque estoy mareado.

He tenido is the present perfect in Spanish: he + past participle (tenido).

In this sentence, he tenido que means I have had to. It describes something that has happened recently and is connected to the present situation.

• Tengo que cancelar = I have to cancel
• He tenido que cancelar = I have had to cancel
• Tuve que cancelar = I had to cancel

In Spain, the present perfect is very commonly used for recent past actions, especially when they still feel relevant now.

Tener que + infinitive means to have to do something.

So:

• tener que cancelar = to have to cancel
• he tenido que cancelar = I have had to cancel

This is one of the most common ways to express obligation or necessity in Spanish.

Examples:

• Tengo que estudiar = I have to study
• Hemos tenido que salir = We have had to leave

Because after tener que, Spanish uses an infinitive.

So the pattern is:

• tener que + infinitive

That is why you get:

• he tenido que cancelar

not:

• he tenido que cancelado ❌

Cancelado is a past participle, but here the sentence needs the plain verb form cancelar.

Spanish often leaves out subject pronouns because the verb ending already shows who the subject is.

• He tenido already means I have had
• so yo is not necessary

You could say Yo he tenido que cancelar..., but it usually sounds more emphatic, as if you are stressing I.

This is very normal in Spanish:

• Estoy cansado = I am tired
• Voy mañana = I’m going tomorrow

Because videollamada is a feminine noun, so it takes la.

• la videollamada = the video call

Spanish nouns have grammatical gender, and the article has to match:

• el libro
• la mesa
• la videollamada

Even if English does not mark nouns this way, Spanish always does.

Porque means because and introduces the reason.

So the sentence structure is:

• He tenido que cancelar la videollamada = I have had to cancel the video call
• porque estoy mareado = because I’m dizzy / feeling unwell

Be careful not to confuse:

• porque = because
• por qué = why

Examples:

• No voy porque estoy cansado = I’m not going because I’m tired
• ¿Por qué no vas? = Why aren’t you going?

Because mareado describes a temporary state, so Spanish uses estar, not ser.

• estoy mareado = I feel dizzy / I’m feeling sick
• soy mareado would sound wrong in this context

A useful rule:

• ser = identity, permanent traits, classification
• estar = states, conditions, locations

Since dizziness is a temporary condition, estar is the correct verb.

In Spain, mareado usually means dizzy, light-headed, or sometimes queasy / motion-sick / unwell depending on context.

So estoy mareado can mean:

• I’m dizzy
• I’m feeling faint
• I’m feeling sick
• I’m feeling nauseous

The exact English translation depends on the situation. In this sentence, it suggests the speaker feels physically unwell enough to cancel the call.

Because it agrees with the speaker’s gender.

If the speaker is male, or identifying grammatically as masculine:

• estoy mareado

If the speaker is female:

• estoy mareada

This is adjective agreement, which is very common in Spanish.

Other examples:

• Estoy cansado / cansada
• Estoy preocupado / preocupada

Possibly, but cancelar is the most natural general choice here.

• cancelar = to cancel
• anular = to annul / cancel formally; often sounds more official or technical
• suspender = to suspend / call off / postpone, depending on context

For an everyday video call, cancelar la videollamada is the most straightforward and idiomatic option.

Spanish word order is often similar to English, and this sentence is actually very natural and straightforward:

• main clause: He tenido que cancelar la videollamada
• reason clause: porque estoy mareado

Spanish could sometimes move things around for emphasis, but this standard order is the most neutral one.

It works as:

• action first
• reason second

That makes it clear and natural.

Yes. Videollamada is a normal and widely used word in Spain for video call.

You may also hear:

• hacer una videollamada = to make a video call
• tener una videollamada = to have a video call

It is a compound noun:

• video
• llamada

Together: videollamada.

Yes, depending on context.

For example:

• He tenido que cancelar porque estoy mareado.
• He cancelado la videollamada porque estoy mareado.

The original sentence is already natural, but Spanish often drops information that is obvious from context. If both people already know which call is being discussed, la videollamada could be omitted.

The full version is useful when you want to be explicit and clear.
