The infinitive is the citation form of each verb. It is formed with the present tense stem and the ending -en or, more seldom, with the ending -n.
| Examples |
| spiel-en |
| fahr-en |
| tanz-en |
| sprech-en |
| änder-n |
Note: The infinitive ending -n is used in verbs sein and tun and when the verb stem ends in -el and -er.
