The verb geben in German is when you give something away, give it away, or even give it as a gift. Imagine you have a delicious chocolate bar and you decide to share a piece with a friend - you gibst him the chocolate bar. What if your mom gives you pocket money? She gibt you a euro!
This verb translates as “to give”, but it can actually do more than that. For example:
Ich gebe dir einen Tipp. - I'm giving you some advice.
Kannst du mir mir das Buch geben? - Can you give me a book?
Es gibt viele Parks in dieser Stadt. - There are many parks in this city.
This last example is the trickiest! Es gibt means “is” or “exists”, and here geben no longer conveys anything to anyone, but you can't get anywhere in German without it.
So, if you want to generously “give away” knowledge in German, memorize geben - it is always at hand!
