Questions & Answers about Zu Hause lese ich meinen Mietvertrag noch einmal, weil ich eine Frage zur Mülltrennung habe.

Why is Zu Hause at the beginning, and why does the sentence start with lese ich instead of ich lese?

German is often verb-second (V2) in main clauses. Whatever you put in position 1 (the Vorfeld) can be moved there for emphasis or context—here Zu Hause (At home).
Because Zu Hause takes the first slot, the finite verb must still come second, so you get Zu Hause lese ich ... (not Zu Hause ich lese ...).
If you start with the subject, you’d say Ich lese zu Hause ....

Why is zu Hause written as two words, and what does it mean exactly?

zu Hause (two words) is a fixed expression meaning at home (location/state). It’s different from:

• nach Hause = (going) home (direction)
• von zu Hause = from home

So Zu Hause lese ich ... describes where you are while reading.

Why is Hause capitalized in Zu Hause?

In zu Hause, the word Hause is historically a noun form (related to das Haus), and in modern spelling it’s commonly capitalized as part of the set phrase zu Hause / Zu Hause. At the start of a sentence, it’s capitalized anyway.
