Definition

A reflexive verb is a verb that has an object which is the same as the subject of the verb ==> the action of the reflexive verb is something one is doing to or for oneself.  Some verbs are reflexive all or most of the time, others are only reflexive when used in certain ways.  Here are some examples to illustrate what is meant by this definition.  Where the infinitive is listed with a reflexive pronoun in the table below, the verb is reflexive all or most of the time; in many cases, the corresponding English verb is not reflexive.  This is discussed in more detail below.

sich erkälten Er erkältetsich. He catches a cold. [literally: he “colds” himself ==> he is the subject, and he is also the object]
sich anziehen Sie ziehtsich an. She gets dressed. [literally: she dresses herself ==> she is the subject, and she is also the object]

The only way for this verb not to be reflexive is if someone dresses someone else.

sich amüsieren Ich habemich auf dem Nagelbett amüsiert. I enjoyed myself on the bed of nails. [==> I am the subject, and I am also the object]

The only way for this verb not to be reflexive is if someone amuses someone else.

machen Er machtsich einen Teller Käsespätzle. He makes himself a plate of cheese Spätzle. [==> He is the subject, and he is doing this for himself, so he is also the (indirect) object (the Spätzle being the direct object in this case)]
lieben Erst muss man sichselbst lieben.  Dann kann man Deutsch lieben. First one must love oneself.  Then one can love German. [In the first sentence one is loving oneself, i.e. one is the subject and the object, and the sentence is reflexive.  In the second sentence, one is the subject and German is the object; these are different, so the second sentence is not reflexive.]
weh tun Er hat sichauf dem Nagelbett weh getan.  Ich habe ihm nicht weh getan. He hurt himself on the bed of nails. I did not hurt him.  [In the first sentence he is the subject, and he is also the object and the sentence is reflexive.  In the second sentence, I am and he is the object; these are different, so the second sentence is not reflexive.]

Table of Reflexive Pronouns

The reflexive pronouns are similar to the regular accusative and dative pronouns, but in the 3rd person singular and plural, there is only one form of the reflexive pronoun for all genders and both accusative and dative: sich:

Person Accusative Reflexive Pronoun Dative Reflexive Pronoun
ich mich mir
du dich dir
er/sie/es sich sich
wir uns uns
ihr euch euch
sie/Sie sich sich

Compare this to the table of regular accusative and dative pronouns:

Person Accusative  Pronoun Dative  Pronoun
ich mich mir
du dich dir
er/sie/es ihn/sie/es ihm/ihr/ihm
wir uns uns
ihr euch euch
sie/

Obligatory and Optional Reflexives

Obligatory Reflexives

Languages differ in what actions they consider to be reflexive.  Some verbs will always be accompanied by a reflexive pronoun, e.g. Germans always think of sich kämmensich waschensich beeilen [=to hurry up] and even sich erkälten [=to catch a cold] as something one is doing to oneself.  In general, the reflexive is obligatory for many more verbs in German than in English; a representative list of such reflexive verbs is provided in the last section; here is an exceprt from that list related to grooming and one’s daily routine:
