Grammatical/Ungrammatical

A string of words is grammatical if it follows the principles of grammar of a language, ungrammatical if it does not. For instance, in English the sentence "John did ran" is ungrammatical, and "John ran" is grammatical. According to Chomsky, grammatical sentences should be judged as appropriate sentences of a language by native speakers of the language. Whether the principles of grammar are innate and whether they are explicitly represented in the brain are matters of debate.
