Learn Hardcore German: Irgendjemand hat den Stecker gezogen, aber niemand sagt etwas. - Somebody pulled the plug, but nobody says anything.

Both refer to an unspecified person. jemand = someone. irgendjemand = someone or other / anyone (at all). The prefix irgend- makes it more indefinite and often signals “we don’t know or care who exactly.” In this sentence, irgendjemand emphasizes that the identity is unknown.

What tense is hat … gezogen, and why is gezogen at the end?

It’s the present perfect (Perfekt), the default past in spoken German. In main clauses with Perfekt, the finite auxiliary (hat) sits in the 2nd position and the past participle (gezogen) goes to the clause-final position: Irgendjemand [1] hat [2] … gezogen [end].

Why is it hat and not ist gezogen?

The auxiliary is haben because ziehen here is transitive (it takes a direct object: den Stecker). sein is used mainly with intransitive verbs of motion or change of state. Contrast:

Transitive: Wir haben den Schlitten gezogen.
Intransitive motion: Wir sind nach Berlin gezogen.

What does the phrase den Stecker ziehen mean—literal and figurative?

Literally, “to pull the plug (out of the socket).” Figuratively, it’s an idiom meaning “to pull the plug on something,” i.e., to shut something down, end a project, cut off support/funding, or stop an activity: Die Firma hat dem Projekt den Stecker gezogen.

Why is it den Stecker (and not der/dem/einen Stecker)?

den is masculine accusative singular; Stecker (plug) is masculine. It’s the direct object, so accusative is required.
The idiom often uses the definite article (den) even in a generic sense (much like English “pull the plug”).
You’d say einen Stecker if you meant “a plug (one of several),” not the idiomatic “the plug (on something).”

Why is there a comma before aber, and what happens to word order after aber?

A comma is mandatory before the coordinating conjunction aber when it links two main clauses. aber does not change word order; the second clause stays verb‑second: aber [0] niemand [1] sagt [2] …

Why is it niemand sagt etwas and not niemand sagt nichts?

Standard German avoids double negation. Since niemand already negates, the object must be the non‑negative etwas (“something/anything”). Niemand sagt nichts is common in some dialects (negative concord) but nonstandard in formal German.

Can I use was instead of etwas?

Yes, was is a very common colloquial reduction of etwas. So niemand sagt was is natural in informal speech; niemand sagt etwas is neutral/formal.

What’s the subject–verb agreement with niemand?

niemand is grammatically singular and takes 3rd‑person singular verb forms: niemand sagt, not niemand sagen.

Can I front the object for emphasis, like Den Stecker hat irgendjemand gezogen?

Yes. German allows fronting for emphasis. The verb still stays in 2nd position:

Neutral: Irgendjemand hat den Stecker gezogen.
Emphatic object: Den Stecker hat irgendjemand gezogen.

Is Irgendjemand capitalized for a special reason? And why is Stecker capitalized?

Irgendjemand is capitalized here only because it starts the sentence; otherwise it’s lowercase (it’s a pronoun). Stecker is a noun, and all nouns are capitalized in German.

How do jemand and niemand decline in other cases?

Standard forms:

jemand: nominative jemand, accusative jemanden, dative jemandem, genitive jemandes (rare; often replaced by von jemandem).
niemand: nominative niemand, accusative niemanden, dative niemandem, genitive niemands (rare; often replaced by von niemandem). In casual speech, you’ll sometimes hear forms without endings (e.g., Ich sehe niemand), but the forms with endings are standard.

What’s the difference between niemand and keiner?

Both mean “no one.” niemand is a standalone pronoun; keiner declines like kein and can feel a bit more colloquial or emphatic:

Niemand sagt etwas.
Keiner sagt was. (very common in speech)

Why aber and not sondern?

sondern is used after a negation to correct/replace something: nicht A, sondern B. Here there’s no prior negation that’s being corrected, so aber (“but/however”) is the right choice.

Could I use doch instead of aber?

Yes. As a coordinating conjunction, doch can substitute for aber with a slightly more formal/literary tone: …, doch niemand sagt etwas. Word order remains verb‑second in the clause after doch.

When would I use Präteritum (zog den Stecker) instead of Perfekt (hat den Stecker gezogen)?

In spoken German, Perfekt is preferred. In written narratives or reports, Präteritum is common: Irgendjemand zog den Stecker, aber niemand sagte etwas. Both are correct; choice depends on register.

Why not just say zieht (present) if the situation is current?

The sentence reports a completed past action (the plug has already been pulled). If it were happening right now, you’d use present: Irgendjemand zieht den Stecker, aber niemand sagt etwas. Context decides.

Is ziehen a separable verb here? Why is the participle gezogen?

ziehen itself is not separable; it’s an irregular strong verb with the participle gezogen. The phrase den Stecker ziehen is a verb–object collocation, not a separable prefix verb. Don’t confuse it with separable compounds like umziehen → ist/hat umgezogen (depending on meaning).
