Satztyps
Satztyps is a term used in linguistics and language teaching to describe how sentences can be categorized by function and by structure. In German grammar, the concept helps explain how sentences communicate different meanings and how their form supports these meanings. Two primary axes are used: the functional type, which indicates what a sentence does, and the structural type, which shows how the sentence is built.
Functional types group sentences by their communicative purpose. The main categories are Aussagesatz (declarative sentence), Fragesatz
Structural types classify sentences by their internal organization. A simple Satz consists of a single clause
Terminology varies by grammar tradition. Some sources use Satzarten and others Satztypen, sometimes overlapping in meaning.
