Linguist Noam Chomsky, among many others, has argued that the lack of an upper bound on the number of grammatical sentences in a language, and the lack of an upper bound on grammatical sentence length (beyond practical constraints such as the time available to utter one), can be explained as the consequence of recursion in natural language. In mathematics, logic and computer science, a formal language (a set of finite sequences of symbols taken from a fixed alphabet) is called recursive if it is a recursive subset of the set of all possible finite sequences over the alphabet of the language. Equivalently, a formal language is recursive if there … See more There are two equivalent major definitions for the concept of a recursive language: 1. A recursive formal language is a recursive subset in the set of all possible words over the alphabet of the language. 2.

Thus, a simple example of a recursive language is the set L={abc, aabbcc, aaabbbccc, ...}; more formally, the set See more Recursive languages are closed under the following operations. That is, if L and P are two recursive languages, then the following languages are recursive as well: • The Kleene star $${\displaystyle L^{*}}$$ • The image φ(L) under an e-free homomorphism See more WebYou can think of c o R E as recursively enumerating the complement (hence the name).
