of the language of which it is a part. Well-formed words or phrases are grammatical, meaning they obey all relevant rules of grammar. In contrast, a form that violates some grammar rule is ill-formed and does not constitute part of the language. A word may be phonologically well-formed, meaning it conforms to the sound pattern of the language. For example, the nonce word ''wug'' coined by Jean Berko Gleason is phonologically well-formed, so informants are able to pluralize it regularly. A word, phrase, clause, or utterance may be grammatically well-formed, meaning it obeys the rules of morphology and

syntax In linguistics, syntax ( ) is the study of how words and morphemes combine to form larger units such as phrases and sentences. Central concerns of syntax include word order, grammatical relations, hierarchical sentence structure (constituenc ...

. A semantically well-formed utterance or sentence is one that is meaningful. Grammatical well-formedness and semantic well-formedness do not always coincide. For example, the following sentence is grammatically well-formed, but has no clear meaning. :'' Colorless green ideas sleep furiously.'' The concept of well-formedness was developed in

Gradient well-formedness

Gradient well-formedness is a problem that arises in the analysis of data in generative linguistics, in which a linguistic entity is neither completely grammatical nor completely ungrammatical. A native speaker may judge a word, phrase or pronunciation as "not quite right" or "almost there," rather than dismissing it as completely unacceptable or fully accepting it as well-formed. Thus, the acceptability of the given entity lies on a "
