Me enteré esta mañana de que Laura va a cambiar de trabajo, aunque yo ya sospechaba algo.

Because the verb here is enterarse de, which is a pronominal verb and means to find out or to learn about something.

• enterar by itself usually means to inform someone:
  • Le enteré de la noticia is not the usual modern phrasing; more commonly you would use informar.
• enterarse de means to find out:
  • Me enteré de la noticia = I found out about the news

So me is not optional here. It is part of the verb structure.

In this sentence:

• Me enteré = I found out

The preterite is used because this refers to a completed action at a specific moment in the past: this morning.

• Me enteré esta mañana = I found out this morning

That is a clear, finished event.

If you used the imperfect, me enteraba, it would sound more like:

• I was finding out
• I used to find out

That does not fit well here. The speaker is talking about the moment they learned the news, so the preterite is the natural choice.

Because enterarse normally takes the preposition de:

• enterarse de algo = to find out about something
• enterarse de que + clause = to find out that...

So:

• Me enteré de la noticia = I found out about the news
• Me enteré de que Laura va a cambiar de trabajo = I found out that Laura is going to change jobs

This is standard Spanish. The de belongs to the verb enterarse.

Because enterarse de que introduces information that the speaker presents as a fact, not as a wish, doubt, or possibility.

So you use the indicative:

• Me enteré de que Laura va a cambiar de trabajo

The speaker is saying this as something real that they learned.

You would not normally use the subjunctive after enterarse de que in this kind of sentence.

Ir a + infinitive is a very common way to talk about the future in Spanish.

• va a cambiar = is going to change
• cambiará = will change

Both can be correct, but ir a + infinitive is very common in everyday speech and often sounds more natural and conversational.

So:

• Laura va a cambiar de trabajo = Laura is going to change jobs
• Laura cambiará de trabajo = Laura will change jobs

In many contexts, the first one feels more colloquial and immediate.

In Spanish, when you mean to change from one job to another, the usual expression is cambiar de trabajo.

• cambiar de trabajo = to change jobs
• literally, to change of job

The preposition de is part of the idiomatic expression.

Compare:

• cambiar de casa = to move house / change homes
• cambiar de ropa = change clothes
• cambiar de idea = change one’s mind

So de is important here.

Aunque means although, even though, or sometimes though.

Here it introduces a contrast:

• Me enteré esta mañana... = I found out this morning...
• aunque yo ya sospechaba algo = although I already suspected something

So the idea is:

• the speaker only found out this morning,
• but they had already had some suspicion before that.

It connects two ideas that are slightly opposed.

Because ya sospechaba algo describes an ongoing mental state or background situation in the past.

• sospechaba = I suspected / I had my suspicions
• It was not a single completed event.
• It was something the speaker already felt before finding out.

This is a classic use of the imperfect:

• background information
• ongoing states
• repeated or habitual past situations

So the contrast is:

• Me enteré = completed event
• yo ya sospechaba algo = existing background suspicion

Normally, sospechaba is better here.

Sospeché would suggest a more specific, completed moment of suspicion:

• I suspected something at one particular moment

But the sentence is not really about one isolated instant. It means the speaker had already been suspecting something before the news was confirmed. That is why the imperfect sospechaba fits better.

So:

• ya sospechaba algo = I already suspected something / I already had a feeling
• more natural here

Yes, Spanish often omits subject pronouns because the verb ending already shows the subject.

So you could say:

• aunque ya sospechaba algo

That would still be correct.

But yo can be included for emphasis, contrast, or clarity. Here it slightly highlights the speaker’s personal point of view:

• aunque yo ya sospechaba algo = although I already suspected something

It adds a subtle sense of:

• as for me
• I, personally, already suspected something

So yo is not required, but it is perfectly natural.

Ya means already here.

It shows that the suspicion existed before the speaker found out the news.

So the timeline is:

1. the speaker had some suspicion
2. this morning, they found out for sure

Without ya, the sentence would still make sense:

• aunque yo sospechaba algo

But ya makes the sequence clearer and more natural:

• although I already suspected something

Algo means something.

In this sentence, it suggests that the speaker did not know the full truth, but sensed that something was going on.

• sospechaba algo = I suspected something
• more naturally in English: I had a feeling / I suspected as much

Why not the others?

• nada = nothing
  That would mean the opposite.
• eso = that
  This would point to something more specific and usually already identified.

So algo is the natural choice when the speaker only had a vague suspicion.

Yes. Esta mañana usually means this morning, and in context it often refers to the morning of the current day.

In Spanish, it can be used with the preterite:

• Me enteré esta mañana = I found out this morning

Even if it is now later in the day, that is still perfectly normal.

This is slightly different from some learners’ expectations, because in English people sometimes avoid certain past forms depending on how they view today. In Spanish, esta mañana with the preterite is completely standard.

Yes, it is natural in Spain.

A native speaker in Spain might also say similar versions such as:

• Esta mañana me he enterado de que Laura va a cambiar de trabajo, aunque yo ya sospechaba algo.
• Me he enterado esta mañana de que Laura cambia de trabajo, aunque ya me lo olía un poco.

A small note: In many parts of Spain, especially in everyday speech, speakers often use the present perfect for recent past events connected to today:

• me he enterado esta mañana

But me enteré esta mañana is also grammatical and understandable. Depending on region and style, one may sound more usual than the other.

Yes. The literal translation is I suspected something, but in natural English you might also say:

• I already had my suspicions
• I already suspected as much
• I already had a feeling

These translations often sound smoother in English, even though the Spanish wording is simple and direct.

So depending on context, yo ya sospechaba algo may be better understood as:

• I already had my suspicions

rather than only the word-for-word version.
