Kompositionalityyn

Kompositionalityyn is a theoretical concept in linguistics and philosophy of language that describes how the meaning of a complex expression is determined by the meanings of its constituent parts and the rules used to combine them. In simpler terms, it's the idea that we can understand the meaning of a sentence or phrase by understanding the meaning of individual words and how they are put together. For example, in the sentence "The cat sat on the mat," the meaning of the whole sentence is derived from the meanings of "the," "cat," "sat," "on," and "the," "mat," and the grammatical structure that connects them.

This principle is fundamental to understanding how humans can generate and comprehend an infinite number of novel sentences from a finite set of words and grammatical rules. Without kompositionalityyn, each sentence would have to be learned as a completely new unit of meaning, making language acquisition and use practically impossible. The concept has been extensively discussed in the philosophy of language, particularly concerning issues of meaning, reference, and understanding. Debates often revolve around the precise nature of the "rules" of composition and whether all meaningful expressions are truly compositional.
