An infinitive is the form of a verb that you find in the dictionary. It is the basic form of a verb before any changes for tense or people are made. In English, the infinitive can be thought of as the to form of a verb, like to eat or to go. German infinitives mostly end in -en, like spiel_en_ (to play).

You can change the infinitive to use different tenses by adding different endings. You can conjugate a verb depending on whom you are talking about.

Conjugate means changing the endings of a verb to match the person doing the action.

You can use the infinitive when using modal verbs and the future tense.

Modal verbs

Modal verbs are verbs like can and must. They need an infinitive to help the sentence make sense. For example, the modal verb 办枚苍苍别苍 (to be able to or can) needs an infinitive to make clear what it is you can do.

  • Ich kann spielen - I can play.
  • Ich kann Klavier spielen - I can play the piano.

The modal verb kann is the second idea in the sentence and the infinitive verb spielen goes to the end of the sentence.
