El elenco entró, y eso que nadie avisó.

Elenco usually means the cast: the group of actors or performers in a play, film, show, etc.

In Spain, elenco is understood and widely used, especially in cultural or media contexts. Depending on context, you might also hear:

• el reparto = the cast
• la compañía = the company / troupe

So in this sentence, el elenco is a singular collective noun referring to a whole group.

Because the grammatical subject is el elenco, which is singular.

• El elenco entró = The cast entered
• Los actores entraron = The actors entered

Even though the cast contains many people, Spanish treats el elenco as one unit here, so the verb is singular: entró.

Entró is the preterite of entrar in the 3rd person singular.

• entrar = to enter / to go in
• entró = he/she/it entered

The preterite is used because this is seen as a completed action in the past: the cast entered. It is a single finished event.

Y eso que is an idiomatic expression. In this sentence, it means something like:

• and that’s despite the fact that...
• even though...
• although...
• and yet...

So:

• El elenco entró, y eso que nadie avisó. = The cast came in, even though nobody gave any warning.

It often introduces a surprising contrast: something happened despite another fact.

Not very naturally.

Word by word, it looks like:

• y = and
• eso = that
• que = that

But as a whole, y eso que functions as a fixed expression. A natural English rendering is usually:

• even though
• and that’s despite the fact that
• and yet

So it is better to learn it as a chunk rather than translating each word separately.

Because when nadie comes before the verb, Spanish does not use an extra no.

• Nadie avisó = Nobody warned / No one gave notice

But if the negative word comes after the verb, then Spanish does use no:

• No avisó nadie

Both mean basically the same thing.

This is a common pattern in Spanish:

• Nadie vino = Nobody came
• No vino nadie = Nobody came

It depends on context. Avisar can mean several related things:

• to warn
• to let someone know
• to notify
• to give notice
• to announce (in some contexts)

In this sentence, nadie avisó most likely means:

• nobody warned anyone
• nobody gave notice
• nobody let people know beforehand

So the idea is that the cast entered unexpectedly, without anyone announcing it or alerting others.

Spanish often leaves out subject pronouns or even unstated subjects when they are not important or are unknown.

• nadie avisó literally means nobody warned / nobody notified

The sentence does not say whom nobody warned, because Spanish can leave that implied if it is obvious from context or not important.

English often needs to be a bit more explicit, but Spanish is comfortable being more compact.

The comma separates the main statement from the contrasting comment introduced by y eso que.

Structure:

• El elenco entró = main fact
• y eso que nadie avisó = surprising contrast/explanation

The comma helps show that the second part is an added remark: the cast came in, even though nobody had announced it.

Yes, in many contexts you could say:

• El elenco entró, aunque nadie avisó.

That would also mean The cast entered, although nobody warned anyone / gave notice.

But there is a nuance:

• aunque is the more general word for although / even though
• y eso que often sounds a bit more conversational and can emphasize the unexpected contrast more strongly

So y eso que can feel slightly more expressive.

A Spaniard would definitely understand it, and it is perfectly acceptable in Spain. However, in everyday speech, some speakers in Spain might more often say reparto in certain contexts, especially for film or TV casts.

For example:

• el elenco de la obra = the cast of the play
• el reparto de la película = the cast of the film

So elenco is correct and natural, but reparto is also very common in Spain.

Yes. Entrar often translates as:

• to enter
• to go in
• to come in

Which one sounds best depends on context.

So:

• El elenco entró could be:
  • The cast entered
  • The cast came in

English chooses the most natural option based on style and situation.
