Reflexive Pronouns: mich, mir, sich

A reflexive pronoun is one that points back at the subject of its own clause: the doer and the receiver of the action are the same person. English marks this with the -self words — myself, yourself, himself — as in "I cut myself." German has a parallel set, but it is organised on a logic English speakers rarely expect. In the first and second persons, German simply reuses the ordinary object pronouns (mich/mir, dich/dir, uns, euch) — there is no special reflexive form at all. Only the third person has a dedicated reflexive word: sich, which is invariable and covers himself, herself, itself, themselves, and the formal yourself/yourselves. And there is a second wrinkle with no English counterpart: German reflexives come in two cases, accusative and dative, and you have to know which one a given sentence calls for.

The full reflexive paradigm

Here is the complete set, accusative and dative side by side. Look at how the first and second persons are identical to the normal personal-pronoun objects, and how the entire third person — singular and plural, all genders, plus formal Sie — collapses into the single form sich.

Two observations make this table much easier to hold in your head. First, uns and euch never change between accusative and dative — one form does both jobs. Second, sich does triple duty: third-person accusative, third-person dative, and every formal Sie — so the only forms you genuinely have to keep distinct are mich/mir and dich/dir, which you already know as ordinary pronouns.

Note the spelling: sich is always lowercase, even when it goes with the capitalised formal Sie. Setzen Sie sich keeps the capital on the pronoun Sie but the lowercase on the reflexive sich.

Accusative or dative? The deciding question

This is the heart of the page, and the part with no English shortcut. A reflexive can be either accusative or dative, and which one you use depends on a single test: is there another (accusative) object in the clause?

• If the reflexive is the direct object — the only thing being acted on — it is accusative.
• If there is already a direct object (typically a thing), the reflexive steps back to the dative, expressing the person for/to whom the action is done.

The textbook contrast is washing. Compare:

In the first sentence there is nothing else being washed — mich is the thing washed, so it takes the accusative. In the second sentence the thing being washed is die Hände (accusative direct object), and the reflexive mir now means "for myself / to myself" — the dative. The same person is doing and benefiting in both, but the grammar reshuffles because a second object has appeared.

This pattern recurs across the language wherever an action is done to one's own body or possessions:

For the body-part construction specifically — sich die Hände waschen, sich die Zähne putzen — German uses the definite article plus dative reflexive rather than a possessive: not meine Hände but mir die Hände. The dative reflexive already tells you whose hands they are. (See articles with body parts and possession.)

A few more accusative reflexives in context

Many common German verbs are inherently reflexive in the accusative — the reflexive is just part of the verb and has no separate "self" meaning to translate. These you simply learn as units:

For more on the difference between verbs that are always reflexive and verbs that are merely being used reflexively, see true vs partial reflexives.

How this differs from English

English does two things that mislead learners here. First, English uses a possessive for body parts — "I wash my hands" — where German uses the dative reflexive plus a plain article ("ich wasche mir die Hände"). Second, English builds every reflexive on a transparent -self word, so it never has to choose a case and never reuses an ordinary object pronoun. German makes you do both: pick the case, and (in the first/second person) reuse the same mich/mir you already use as a non-reflexive object. The payoff of the German system is its economy — third person and formal Sie all share one word, sich, so there is far less to memorise than the English -self series might lead you to fear.

Common Mistakes

1. Using a possessive for body parts instead of the dative reflexive. This is the single most common transfer error, straight from English "my hands."

2. Using ihn/ihm instead of sich in the third person. English "he hurt himself" tempts the object pronoun ihn, but ihn would refer to a different male person. The reflexive must be sich.

3. Using the accusative reflexive when there's a second object. When a thing is also being acted on, the reflexive must go dative — a frequent slip with body-part and clothing verbs.

4. Capitalising sich with formal Sie. Even though Sie is capitalised, the reflexive sich stays lowercase.

5. Forcing a 'self' translation onto inherently reflexive verbs. Verbs like sich freuen or sich beeilen carry the reflexive as part of the lexeme; dropping it is ungrammatical even though English has no "self."

Key Takeaways

• Reflexive pronouns point back to the subject; first and second person reuse the ordinary object pronouns (mich/mir, dich/dir, uns, euch).
• The third person — and formal Sie — uses the single invariable sich for both accusative and dative.
• Choose accusative when the reflexive is the only object; choose dative when there is already a direct object (the body-part construction: sich die Hände waschen).
• uns and euch are identical in accusative and dative; sich covers third person and formal Sie alike.
• sich is always lowercase, even after the capitalised formal Sie.
