When a pronoun is the object of a verb or preposition rather than the subject, German makes you choose between two forms: the accusative (the direct object — the thing acted on) and the dative (the indirect object — the recipient, and the object of dative verbs and prepositions). English mostly merged these long ago, so "him" does double duty in "I see him" and "I give him the book." German keeps them apart, and every single object pronoun forces an explicit accusative-or-dative decision. This page drills the contrasts that trip up English speakers the hardest: ihn vs ihm, sie vs ihr, sie vs ihnen.
The full object paradigm
| Subject (nom.) | Direct object (acc.) | Indirect object (dat.) |
|---|---|---|
| ich | mich | mir |
| du | dich | dir |
| er | ihn | ihm |
| sie (she) | sie | ihr |
| es | es | ihm |
| wir | uns | uns |
| ihr | euch | euch |
| sie (they) | sie | ihnen |
| Sie (formal) | Sie | Ihnen |
Notice the merciful pattern: in the plural, uns and euch are the same in both cases, so you only have to worry about the singular and the third-person plural. The real work is in the third person — exactly where English gives you no help.
Siehst du mich?
Can you see me? (acc. — direct object)
Gib mir bitte das Salz.
Pass me the salt, please. (dat. — recipient)
The third-person contrasts English collapses
Here is the crux. English "him," "her," and "them" each cover two German forms, and you have to pick the right one every time.
| English | Accusative (direct object) | Dative (recipient) |
|---|---|---|
| him | ihn | ihm |
| her | sie | ihr |
| them | sie | ihnen |
The difference between ihn and ihm is a single letter, but it encodes the whole grammatical role of the pronoun. ihn is the thing being acted on; ihm is the person receiving or benefiting. Watch them in the same sentence:
Ich sehe ihn und gebe ihm das Buch.
I see him and give him the book.
In that one clause, the same man is first ihn (the one I see — direct object) and then ihm (the one I give the book to — indirect object). English uses "him" twice and you'd never notice the role switch; German marks it.
Kennst du sie? — Ja, und ich habe ihr gestern geschrieben.
Do you know her? — Yes, and I wrote to her yesterday.
Die Kinder sind müde; bring sie ins Bett und lies ihnen eine Geschichte vor.
The kids are tired; put them to bed and read them a story.
Minimal pairs: kennen vs helfen
The cleanest way to feel the difference is to swap one verb for another and watch the pronoun change. Some verbs take a direct (accusative) object; a special set — the dative verbs, like helfen, danken, gratulieren, gehören, glauben — take a dative object even though English treats it as direct.
Ich kenne ihn gut.
I know him well. (kennen → accusative ihn)
Ich helfe ihm gern.
I'm happy to help him. (helfen → dative ihm)
In English both are plain transitive verbs — "I know him," "I help him" — so nothing warns you that helfen demands the dative. There is no logical reason for it; helfen, danken, antworten and the others simply belong to the dative-verb list, and you have to memorise them. The reward is that once a verb is filed as a dative verb, its pronoun is automatic: helfen always pulls mir, dir, ihm, ihr, uns, euch, ihnen.
Prepositions decide case too
Pronouns after prepositions follow the case the preposition governs. für, ohne, gegen, um take the accusative; mit, nach, aus, bei, von, zu take the dative. So the preposition, not the meaning, sets the form.
Dieses Geschenk ist für dich.
This present is for you. (für → accusative dich)
Kommst du mit mir ins Kino?
Are you coming to the cinema with me? (mit → dative mir)
Ohne ihn fahren wir nicht los.
We're not setting off without him. (ohne → accusative ihn)
This is where the English-driven slip für mir / mit mich comes from: English doesn't change "me" after a preposition, so learners reach for whichever form feels familiar. In German you must check what the preposition governs — für is accusative (für mich), mit is dative (mit mir).
Contrast with English
Modern English has exactly one object form per pronoun: me, you, him, her, it, us, them. It uses that single form for the direct object ("she called me"), the indirect object ("she gave me a call"), and the object of every preposition ("with me," "for me"). German splits this one slot into two, by case. The practical consequence: where an English speaker can switch off and reuse "him," a German speaker has to ask, for every object pronoun, is this accusative or dative? — and the answer comes from the verb or the preposition, not from the meaning of "him." Train yourself to make that decision consciously and the ihn/ihm confusion dissolves.
Common Mistakes
❌ Ich helfe ihn mit den Hausaufgaben.
Incorrect — helfen is a dative verb, so it needs ihm, not ihn.
✅ Ich helfe ihm mit den Hausaufgaben.
I'm helping him with his homework.
❌ Das Buch ist für mir.
Incorrect — für governs the accusative, so it's mich, not mir.
✅ Das Buch ist für mich.
The book is for me.
❌ Kommst du mit mich ins Konzert?
Incorrect — mit governs the dative, so it's mir, not mich.
✅ Kommst du mit mir ins Konzert?
Are you coming to the concert with me?
❌ Ich habe sie das Foto geschickt.
Incorrect — the recipient is the indirect object, so use dative ihr (to her).
✅ Ich habe ihr das Foto geschickt.
I sent her the photo.
❌ Ich danke ihn für die Hilfe.
Incorrect — danken is a dative verb, so it needs ihm.
✅ Ich danke ihm für die Hilfe.
I thank him for the help.
Key Takeaways
- Object pronouns come in two cases: accusative (mich, dich, ihn, sie, es, uns, euch, sie, Sie) and dative (mir, dir, ihm, ihr, ihm, uns, euch, ihnen, Ihnen).
- The third person is where English fails you: him = ihn/ihm, her = sie/ihr, them = sie/ihnen.
- The verb decides the case: sehen, kennen
- accusative; helfen, danken, antworten
- dative.
- accusative; helfen, danken, antworten
- The preposition decides the case after it: für/ohne/gegen
- accusative, mit/von/zu/bei
- dative.
- accusative, mit/von/zu/bei
- uns and euch are identical in both cases — one fewer thing to memorise.
