Koordinationserfordernis

Koordinationserfordernis is a concept in linguistics that refers to the requirement for certain syntactic structures to be coordinated. Coordination is a grammatical process where two or more elements are combined to form a single unit, typically using conjunctions such as "and," "or," or "but." The Koordinationserfordernis principle states that certain syntactic structures must be coordinated if they are to be grammatically correct.

For example, in German, the Koordinationserfordernis principle applies to verb phrases. If two verb phrases are coordinated, they must both be in the same tense and mood. For instance, the sentence "Ich lese und du liest" (I read and you read) is incorrect because the verb "liest" (reads) is in the present tense, while "lese" (read) is in the subjunctive mood. The correct form would be "Ich lese und du liest" or "Ich lese und du lesest."

The principle also applies to noun phrases and adjective phrases. For example, the sentence "Der große und der kleine Hund" (The big and the small dog) is correct because both noun phrases are in the same case and number. However, the sentence "Der große und kleine Hund" (The big and small dog) is incorrect because the noun phrases are not coordinated.

The Koordinationserfordernis principle is an important concept in linguistics because it helps to explain why certain syntactic structures are required to be coordinated. It also provides insights into the structure and function of language.
