In German, the verb verstehen is used in a wide variety of contexts, from hearing what someone says to understanding a fact or the nature of a particular situation or circumstances.

Habt ihr es verstanden? -Ja.

Have you understood it? -Yes.

When you are expressing a deeper level of comprehension, for example being able to follow why something happened the way it did, reconstruct a line of thought, relate to something, or grasp connections, there are additional verbs you can use.

Zwar ist das Wort „Nachhaltigkeit“ in aller Munde,

Indeed, the word "sustainability" is in all mouths (on everyone's lips),

Kinder können das aber kaum nachvollziehen.

but children are hardly able to understand it.

Und das müssen wir wirklich alle begreifen.

One verb that you may encounter is kapieren. In English, we use "to get" to mean "to understand" and this is a similar slang expression. 

Und es wäre schön, wenn du es endlich mal kapieren würdest.

And it would be nice if you would finally understand that.

You can find many examples on Yabla German, but also consider the first four above. Which of these could be replaced with a verb other than verstehen?

I have been speaking German for well over three decades, and although I've only lived in Germany and spoken German on a daily basis for about 15 of those years, I still get confused occasionally by verb prefixes. As I was formulating a freelance job offer the other day, it struck me that I wasn't entirely sure about the difference between bieten and anbieten, both of which are commonly defined as "to offer" in English.

BANNER PLACEHOLDER

To confuse matters even further, the Duden dictionary, which sets the standards for the German language, gives the primary definitions as: anbieten: zur Verfügung stellen und seine Bereitschaft dazu erkennen lassen, zeigen and bieten: anbieten, zur Verfügung, in Aussicht stellen. As you see, the meanings seem nearly identical; in fact, the first definition of bieten is anbieten!

There is, however, a rule of thumb that can help you remember the main difference between the two: anbieten is the specific process or act of making an offer, whereas bieten is a general state or condition, that is, a standing offer or a feature.

To illustrate, here are a few examples of anbieten from Yabla German, first in present tense, then in past tense, then in simple tense as a separable verb:

Kann ich Ihnen einen Kaffee anbieten?

Can I offer you a coffee?

Lastly, when someone is bidding in an auction you would always use the word bieten (or steigern), but never anbieten.

Make up some sentence examples in English using the word "offer" and then translate them into German to see if you understand the principal difference between bieten and anbieten.  Also, do a search on German Yabla for both of the words to find some examples of their usage in a real-world context.

English adjectives for being sure or certain about something are often interchangeable, but German expressions like bestimmt, gewiss, and sicher are more specific to the particular context in which they are used. Let's take a look at all three.

Bestimmt can mean either "definitely"

Du machst Filme und die Leute sagen „Das wird bestimmt so“,

You make films and the people say, "It will definitely be like this",

or in the nominalized noun something specific or in particular:
