Learn Hardcore German: Es ist ziemlich spät, also gehe ich jetzt schlafen. - It is quite late, so I am going to sleep now.

In sentences about weather, time, or general conditions, German often uses es as a “dummy” subject—similar to English it in It’s late. It doesn’t refer to a specific thing; it just fills the required subject slot in the sentence: Es ist ziemlich spät.

What does ziemlich mean, and where does it go in the sentence?

Ziemlich means quite / pretty / rather. It typically sits right before the adjective or adverb it modifies:

ziemlich spät = quite late

You can also use it with other adjectives: ziemlich müde (quite tired), ziemlich teuer (quite expensive).

Why is there a comma before also?

Here also introduces a new main clause and expresses a conclusion (so / therefore). In German, when two main clauses are connected this way, you normally put a comma before the connector:

Es ist ziemlich spät, also gehe ich jetzt schlafen.

(Also note: German punctuation is generally stricter about commas than English.)

Does also mean “also” (as in “too”)?

No—this is a classic false friend. German also usually means so / therefore / thus.
If you mean English “also/too/as well,” you’d commonly use:

auch = also/too
Example: Ich gehe auch schlafen. = I’m going to sleep too.

Why is the verb gehe in second position in also gehe ich ...?

German main clauses follow the V2 rule: the conjugated verb is in the second position. When also is placed first, it counts as position 1, so the verb must come next:

Also | gehe | ich | jetzt | schlafen.

That’s why you get gehe ich, not ich gehe, after also at the start.

Could I also say ..., also ich gehe jetzt schlafen?

In standard written German, also gehe ich ... (with V2) is the normal structure.
..., also ich gehe ... can occur in casual speech when also is more of a discourse filler (like “well, so...”), but it’s less formal and can sound like you’re restarting the sentence.

Why does German say gehe ich schlafen instead of using a separate verb like “to go to sleep”?

German commonly expresses “go to bed / go to sleep” with gehen + infinitive:

gehen schlafen = go (and) sleep / go to sleep
gehen essen = go eat
gehen arbeiten = go work

So ich gehe schlafen is a natural German way to say “I’m going to sleep.”

Why is schlafen at the very end?

Because schlafen is an infinitive, and infinitives typically go to the end of the clause in German when used with another verb (here, gehen):

gehe ... schlafen

This “verb-at-the-end” behavior is very common with infinitives and separable/additional verb parts.

What does jetzt add here, and where can it be placed?

Jetzt means now and adds immediacy: “so I’m going to sleep now.”
It’s flexible, but common positions are:

Also gehe ich jetzt schlafen.
Also gehe ich schlafen. (more neutral; “now” is implied from context)
Also gehe ich jetzt ins Bett. (if you choose that phrasing)

Is ziemlich spät the only natural way to say “pretty late”?

It’s very natural, but there are alternatives with slightly different tone:

Es ist schon spät. = It’s already late. (very common)
Es ist recht spät. = It’s fairly late.
Es ist echt spät. = It’s really late. (more informal)
Es ist sehr spät. = It’s very late. (stronger than ziemlich)
