German Personal Pronouns: ich, mich, mir and the Formal Sie

German personal pronouns are where the case system stops being theory. A noun can hide its case behind an article; a pronoun cannot hide anything. ich, mich and mir are three different words, and choosing between them is a decision you make in almost every sentence.

The good news is that English already has most of this machinery. I and me are two cases of the same pronoun, and so are he and him, she and her, we and us. German keeps one more case than English does, and it splits you three ways. That is the whole difference, and it fits in one table.

The full chart

The three columns are the first three cases: nominative for the subject, accusative for the direct object, dative for the indirect object and after certain verbs and prepositions. There is a genitive set too, but it is so rare in modern German that you can safely ignore it until you meet it in print.

Now look for the shortcuts, because there are plenty:

• wir and ihr only have two forms. uns and euch do both the accusative and the dative job.
• sie, es and Sie do not change in the accusative. Only the masculine er becomes ihn, exactly as the masculine article der becomes den while die and das stay put.
• The dative endings echo the articles. ihm ends in -m like dem; ihr ends in -r like the feminine dative der; ihnen ends in -n like the plural den. If you already know the article chart, you already half-know this one.

The rows that repay the most practice are the first two, mich/mir and dich/dir, because those are the ones you will use most.

Mich or mir: the verb decides

This is the mistake that marks an English speaker faster than any other. English has one word, me, for both jobs:

• He sees me.
• He helps me.

German splits them:

• Er sieht mich. - He sees me. (accusative)
• Er hilft mir. - He helps me. (dative)

Nothing in the meaning tells you which. Seeing and helping both land on me in exactly the same way. The difference is that sehen takes an accusative object and helfen takes a dative one, and that is a fact about the verb, the same way listen needs to in English and hear does not.

So the practical rule is: most verbs take the accusative, and a short list takes the dative. Learn the short list. These are the common ones:

Two of those deserve a note. Das gefällt mir is the everyday way to say I like that, but the grammar is back to front: the thing liked is the subject and the person who likes it is the dative. Du fehlst mir works the same way, and means I miss you, literally you are missing to me.

Prepositions decide too

Most German prepositions have already chosen their case, and a pronoun after one has to follow:

• Dative: mit mir (with me), von dir (from you), zu ihm (to him), bei uns (at our place).
• Accusative: für dich (for you), ohne mich (without me), gegen ihn (against him).

Kommst du mit mir? and Das ist für dich. both use me or you in English and different cases in German, and the preposition is the only reason. The prepositions that can take either case depending on meaning (in, auf, an and a few others) are covered in the cases chart.

Du, ihr or Sie

English has one you. German has three, and picking the right one is a social decision before it is a grammatical one.

• du is one person you are on familiar terms with: a friend, a relative, a child, a pet, and increasingly anyone your own age in a casual setting.
• ihr is several of those people at once: Kommt ihr heute? (Are you all coming today?)
• Sie is the polite form, for one person or several: strangers, shop staff, colleagues in most workplaces, anyone older or more senior.

Formal Sie is always capitalised, in every case: Sie, Ihnen. That capital is the only thing that separates it from sie meaning they, because it uses the same verb form. Sie kommen is you come; sie kommen is they come. In speech, context sorts it out.

If you are not sure, use Sie. The worst that happens is someone smiles and offers you du, which is a small social event in its own right. Getting it wrong in the other direction is the mistake that can land badly, particularly with older people and in shops.

Note that ihr is doing two unrelated jobs in the chart: it is the nominative you all and the dative to her. The verb ending usually settles which one you are looking at. Ihr kommt is you all come; Ich helfe ihr is I help her.

Er, sie and es for things

This is the second classic mistake, and it follows straight from German articles. A German pronoun matches the noun's grammatical gender, not whether it is a person:

• Wo ist der Schlüssel? Er ist hier. - Where is the key? It is here.
• Die Tür ist offen. Sie ist offen. - The door is open. It is open.
• Das Haus ist alt. Es ist alt. - The house is old. It is old.

English says it for all three. German says er, sie and es, because the key is masculine, the door is feminine and the house is neuter. Using es for everything is wrong more often than it is right, and it sounds as odd to a German ear as calling a table she does to yours. It is one more reason to learn every noun with its article.

Word order with two pronouns

When a sentence has a direct and an indirect object, the order depends on what they are:

• Two nouns: dative before accusative. Ich gebe dem Kind das Buch. (I give the child the book.)
• One pronoun, one noun: the pronoun comes first. Ich gebe ihm das Buch. (I give him the book.)
• Two pronouns: accusative before dative. Ich gebe es ihm. (I give it to him.)

The underlying rule is that short, known information goes early, and pronouns are as short and known as it gets. Get the cases right and the order will usually sound right too.

Es with nothing behind it

es has one more job that English gives to it and there: filling the subject slot when there is no real subject at all. German almost always wants a subject in a statement, so es stands in:

• Es gibt ein Problem. - There is a problem.
• Wie geht es dir? - How are you? (literally, how does it go for you?)
• Es tut mir leid. - I am sorry. (literally, it does sorrow to me)

Notice that the person in the last two sits in the dative, dir and mir, exactly like the gefallen sentences above. Once you spot that pattern, a surprising number of everyday phrases stop looking like idioms and start looking like grammar.

The same forms, pointing back

The accusative and dative pronouns do one more job: they double as reflexive pronouns, for when the subject does something to itself. Ich freue mich is I am pleased, literally I gladden myself. For ich, du, wir and ihr the reflexive is simply the form you already know from the chart: mich, dich, uns, euch. Only the third person and formal Sie get a new word, sich. Learn the chart well and reflexive verbs cost you one extra word.

Mistakes English speakers make

Using mich after a dative verb. Er hilft mich is the textbook error. helfen takes the dative, so it is Er hilft mir, every time.

Translating I like with ich gefalle. Ich gefalle means I am pleasing, which is not what you meant. Turn the sentence around: Das gefällt mir. Or use mögen or gern instead: Ich mag das.

Using du with strangers. Grammatically perfect, socially a misstep. Default to Sie with any adult you do not know.

Forgetting the capital on Sie and Ihnen. In writing, Wie geht es ihnen? asks how they are. Wie geht es Ihnen? asks how you are.

Calling every object es. Match the gender: der becomes er, die becomes sie, das becomes es.

What to do next

Learn the chart row by row, out loud, starting with ich, mich, mir and du, dich, dir. Then learn the dative verbs from the table above as a group, because they are few and extremely common. After that, the pronouns take care of themselves: every new verb you meet comes with a case, and every preposition has already chosen one.

The pronouns tell you who is speaking; German verb conjugation gives the verb the matching ending, and the German course drills both together from the first chapter, where ich and du are among the very first words you meet.
