Questions & Answers about Denkst du an mich?

Why does the sentence start with Denkst instead of Du?

In German yes/no questions the finite verb always comes first, then the subject. So Denkst du an mich? literally inverts du denkst (“you think”) to denk­st du (“are you thinking”) to form a question.

Why is the preposition an used here? Could I use über instead?

The verb denken takes a prepositional object with an + accusative when you mean “to think of” someone or something.
Über is used with the different verb nachdenken (“to reflect, to ponder”). You cannot say denken über mich, but you can say nachdenken über mich.

Why is it mich and not mir?

Here an governs the accusative case to mark the target of your thought, so you need mich.
When an indicates location (e.g. an der Wand), it takes the dative (der Wand), but for the action of thinking “of me,” it’s always accusative.

Is denken an a separable verb? Why can’t I say Denkst du mich an?
