Using Gerunds and Infinitives
Mit Gerundien und Infinitive

Gerunds and infinitives are verb forms that can take the place of a noun in a sentence. The following guidelines and lists will help you figure out whether a gerund or infinitive is needed.

Following a verb (gerund or infinitive)

Both gerunds and infinitives can replace a noun as the object of a verb. Whether you use a gerund or an infinitive depends on the main verb in the sentence. Consult the lists below to find out which form to use following which verbs.

I expect to have the report done by Friday. [INFINITIVE]
I anticipate having the report done by Friday. [GERUND]
