Yes/No Questions Edit
Questions can be asked by switching the subject and verb. For instance, "Du verstehst das." (You understand this) becomes "Verstehst du das?" (Do you understand this?). These kinds of questions will generally just elicit yes/no answers. In English, the main verb "to be" follows the same principle. "I am hungry." becomes "Am I hungry?". In German, all verbs follow this principle. There's no do-support.
This skill contains both questions and statements.
