Questions & Answers about Ich werde den Schmuck in den Safe legen.
How could I use this lesson's grammar to ask 'What kind of jewelry will you put in the safe?'
You would ask: Was für einen Schmuck wirst du in den Safe legen? Because der Schmuck (the jewelry) is a masculine noun acting as the direct object (accusative case), the ein- part of the phrase takes the masculine accusative ending -en.
Why do we use in den Safe (accusative) instead of in dem Safe (dative)?
The preposition in is a 'two-way' preposition. It takes the accusative case when there is movement towards a destination, like putting the jewelry into the safe. If the jewelry were already resting inside the safe, you would use the dative case to show a fixed location: Der Schmuck liegt in dem Safe.
Could I use the verb liegen instead of legen here?
No, because they have different meanings. Legen means 'to lay' or 'to put' (an action you do to an object), while liegen means 'to lie' or 'to be located' (a state of rest). Since you are actively moving the jewelry, you must use legen.
Why is the verb legen at the very end of the sentence?
This sentence is in the future tense, which uses the helping verb werden (conjugated here as werde). In German, when you have a conjugated helping verb in the normal second position, the main action verb (legen) gets pushed to the very end of the sentence in its basic dictionary form (infinitive).
