Surface structures and deep structures are concepts that are used in NLP to explain the metamodel of a language. They reflect two states of thought - what a person experiences and what he ultimately says.
Have you ever noticed that the experiences within us are much fuller and more colorful than those that we can express verbally? This complete picture of our feelings is. It consists of conscious and unconscious components, but most of it, of course, is not conscious: a huge layer of sensations and thoughts is beyond the capabilities of verbal communication. Deep structure is the first, not yet formed, step towards the final formulation of a sentence and the expression of words out loud or in writing. - this is how a person ultimately formalized his experiences into a verbal form. Spoken or written words often do not contain even a small part of what was in the deep structures. As mentioned above, a lot is simply not conveyed by words, but some thoughts are lost due to three processes that simulate the final verbal form of the language: omission, distortion and generalization of information. The ratio of deep and surface structures can be simplified in any sentence. For example: "I am studying the metamodel" and "The metamodel is being studied by me." In these sentences, the original thought, i.e. deep structure, one, but thought is framed in different ways. The design is the surface structure. The study and understanding of these terms is necessary for mastering the basics of NLP, in particular its fundamental theory - the metamodel of language.
