Hey there! Today, we're going to talk about two of the most important verbs in the German language: "haben" and "sein." These verbs are absolute powerhouses, and once you master them, they'll become your best friends in constructing sentences and expressing yourself in German. So, let's get started!

First things first, let's talk about "haben." In German, "haben" means "to have." It's an irregular verb, which means it doesn't follow the regular pattern of verb conjugation. But don't worry, this verb is actually quite common in German, so you'll get used to it in no time. Here's how "haben" is conjugated:

Now, let's move on to "sein." "Sein" means "to be" in German, and just like "haben," it's an irregular verb. Here's how "sein" is conjugated:

It's crucial that you memorize these forms thoroughly as they'll be used for many purposes in German. The exercise on the next screen will help you with that. Do it until you can recite all forms of haben and sein in your sleep.

A few things worth noticing

1. You might have noticed the three forms of "sie" above:
   "sie" = she
   "sie (plural) = they
   "Sie (formal) = you, Sir / Ma'am or you, Sirs / Ma'ams
   
   Don't worry about remembering that right now. You'll get used to that over time and context is always your friend. Just know that there are three kinds of "sie" (of which one - the formal one - is always capitalized). We'll talk abou the capital "Sie" later on.
   
   
2. I numbered the forms above 1. 2. 3. That's because we refer to them as follows:
   The first person singular is "ich"
   The second person plural is "wir"
   
   You don't really have to do that and I won't do that (too often) in this course either. But it's good to know about this.
   
   
   
3. Last but not least, the verb "sein" is THE most irregular verb you'll come across. All other irregular verbs show a certain consistency in regards of how they change and their endings which are almost always the same as the endings of the regular verbs.
