This lesson assumes you already know the case rules from Prepositions and Case. Every blank here already has the right case built into the sentence — the only decision is which preposition fits the meaning.

The accusative group used throughout:

Two traps are worth knowing in advance, especially if your native language uses one word where German splits the idea into several:

• seit vs. für vs. während — all three can show up as "for"/"during" in English, but they aren't interchangeable. Seit marks the starting point of something still true now (Ich wohne seit 2018 hier). Für measures a fixed, intended length, usually planned or future (Ich buche das Zimmer für drei Nächte). Während describes a period something happens inside, without measuring how long (Während des Sommers arbeite ich dort).
• aus vs. von — both can mean "from," but aus is for origin — a country you're from, a material something is made of. Von marks a starting point of movement, or who gave/sent something. Compare Ich komme aus der Slowakei (origin) with Der Zug kommt von Bratislava (departure point).

If a preposition here doesn't match your first instinct, it's rarely a vocabulary gap — it's that your native language groups these ideas differently than German does. Read the hint after each answer; it explains the rule, not just the correct word.
