Renunció por la presión.

Because Spanish often drops subject pronouns when the verb form already tells you who the subject is.

Renunció is a third-person singular form, so it can mean:

• he resigned
• she resigned
• you resigned (formal usted)

Spanish normally leaves out él / ella / usted unless the speaker wants emphasis, contrast, or clarity.

So:

• Renunció por la presión. = He/She/You (formal) resigned because of the pressure.

It is the preterite tense, specifically the third-person singular of renunciar.

• infinitive: renunciar = to resign / to give up
• preterite: renunció = resigned

The preterite is used for a completed action in the past.

Examples:

• Ayer renunció. = He/She resigned yesterday.
• Renunció la semana pasada. = He/She resigned last week.

The accent mark shows which syllable is stressed.

• renunció is pronounced roughly reh-noon-see-O
• the stress falls on the last syllable: -ció

It also helps distinguish this past form from forms without that final stressed ending.

For learners, the key point is:

• renunció = he/she/you formal resigned

Por is used here to express the cause or reason for the resignation.

So por la presión means:

• because of the pressure
• due to the pressure

This is a very common use of por.

Examples:

• Lo hizo por miedo. = He did it out of fear.
• Cancelaron el evento por la lluvia. = They cancelled the event because of the rain.

So in this sentence, por answers the question why did he/she resign?

Spanish often uses the definite article more than English does.

Here, la presión refers to the pressure as a known or understood situation:

• pressure from work
• media pressure
• family pressure
• political pressure
• etc.

English sometimes says because of pressure without the, but Spanish very naturally says por la presión.

You could sometimes hear por presión, but por la presión sounds more specific and grounded in a particular context.

Often, yes. Renunciar commonly takes a when you say what someone gives up or resigns from.

Examples:

• Renunció al trabajo. = He/She resigned from the job.
• Renunció a su cargo. = He/She resigned from his/her position.
• Renunció a sus derechos. = He/She gave up his/her rights.

But in Renunció por la presión, the sentence is not saying what they resigned from. It is saying why they resigned.

So:

• renunció = the action
• por la presión = the reason

Both ideas can appear together:

• Renunció a su cargo por la presión. = He/She resigned from the position because of the pressure.

Yes. Renunciar can mean:

• to resign from a job or position
• to give up
• to renounce
• to forgo

It depends on the context.

Examples:

• Renunció al puesto. = He/She resigned from the post.
• Renunció a la oportunidad. = He/She gave up the opportunity.
• Renunció a sus privilegios. = He/She renounced his/her privileges.

So in your sentence, the exact English translation depends on the wider context, although resigned because of the pressure is often the most natural interpretation.

By itself, renunció does not tell you whether the person is:

• he
• she
• usted (you, formal)

Spanish verbs often do not mark gender in the same way English pronouns do, so you need context to know who it is.

For example:

• El ministro renunció por la presión. = The minister resigned because of the pressure.
• María renunció por la presión. = María resigned because of the pressure.
• Usted renunció por la presión. = You resigned because of the pressure.

Yes. Debido a la presión also means due to the pressure.

Compare:

• Renunció por la presión.
• Renunció debido a la presión.

Both are correct. The difference is mostly one of style:

• por la presión = more common, direct, everyday
• debido a la presión = a bit more formal or explanatory

In ordinary speech, por is very common.

Renunció is absolutely correct and common in Spain. However, in some contexts, especially politics or public office, Spanish from Spain also often uses dimitió.

Compare:

• Renunció por la presión.
• Dimitió por la presión.

Both can mean He/She resigned because of the pressure, but dimitir is especially common for resigning from an official or important post.

So:

• renunciar = broad, general
• dimitir = very common in Spain for formal resignation from office

Yes, although Renunció por la presión is perfectly natural.

You might also see:

• Por la presión, renunció.
• Renunció por la presión mediática.
• Renunció por la presión de su partido.

Putting por la presión first can add emphasis to the reason:

• Por la presión, renunció. = Because of the pressure, he/she resigned.

The basic meaning stays the same.
