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?

No — an in denken an is a preposition, not a separable prefix. It forms a prepositional object which stays together (an mich). Saying Denkst du mich an? would treat an like a prefix, which isn’t correct here.

How is denken an different from nachdenken über?

• denken an = “to think of someone/something” (a quick thought or remembrance)
• nachdenken über = “to think about / reflect on” something (more deliberate, analytical)
  They use different verbs and prepositions and have distinct nuances.

How would I ask this formally or to more people?

• Formal (Sie-form): Denken Sie an mich?
• Plural informal (ihr-form): Denkt ihr an mich?

How do I ask the same thing in the past tense?

Use the perfect tense with haben + past participle gedacht, keeping the prepositional object at the end:
Hast du an mich gedacht? (“Did you think of me?”)

Is there a way to stress “right now” (continuous aspect)?

German doesn’t have a separate present-continuous. You simply add a time adverb:
Denkst du gerade an mich? or Denkst du im Moment an mich?

How do I pronounce Denkst? Do I say all the consonants?

In Standard German Denkst is pronounced [dɛŋkst]:

• d as in English day
• enk with a nasal ng like in sing
• st as two separate sounds, s
  • t (not “sch”)
    You do hear both the k and the s, so it’s not reduced to just “denk.”
