flatestruktur
Flatestruktur is a term used in linguistics to describe the observable syntactic form of a sentence—the arrangement of words and phrases as it is spoken or written. It is commonly contrasted with dypstruktur, or deep structure, which refers to the underlying, more abstract representation of meaning and grammatical relations inside a sentence. In generative grammar, transformations can convert a deep-structure representation into a surface-structure representation; for example, movement of a wh-word can alter the surface order without changing the core meaning. The concept helps linguists analyze how different languages realize the same underlying structures and how surface variations relate to interpretation.
Beyond linguistics, flatestruktur is also used in organizational theory and practice to describe flat organizational structures.
