Expressing obligation in German, Italian, French, and Spanish

There are a number of ways to express obligation in language. My go to expressions involve the use

of auxiliary, or helping, verbs. I've written a list of those helping verbs below. In this lesson I'll focus solely on a simple sentence; so, there will be no conjunctions or changes of subjects.

Some of these expressions of obligation overlap with expressions of intention, but that's okay. They're all useful to know and even follow the same syntax.

As per usual, I will work in the first person, singular as a jumping off point.
