German Grammar 104 – To Be – Sein

Most verbs in German are regular, but “sein“ – to be, is one of the irregular verbs. It’s used in a very similar way to English.

As it is a very important verb you will use it a lot. It also is used to form tenses and other grammatical forms.

One important difference is that German has only one present tense, so while in English you use forms with the verb ‘to be’ like: “I am cooking“, in German there exists only the simple form “Ich koche“ (lit. “I cook“).
