Empty category
In linguistics, an empty category, which may also be referred to as a covert category, is an element in the study of syntax that does not have any phonological content and is therefore unpronounced. Empty categories exist in contrast to overt categories which are pronounced. When representing empty categories in tree structures, linguists use a null symbol (∅) to depict the idea that there is a mental category at the level being represented, even if the word(s) are being left out of overt speech.
Syntactic movement
Syntactic movement is the means by which some theories of syntax address discontinuities. Movement was first postulated by structuralist linguists who expressed it in terms of discontinuous constituents or displacement. Some constituents appear to have been displaced from the position in which they receive important features of interpretation. The concept of movement is controversial and is associated with so-called transformational or derivational theories of syntax (such as transformational grammar, government and binding theory, minimalist program).
Principles and parameters
Principles and parameters is a framework within generative linguistics in which the syntax of a natural language is described in accordance with general principles (i.e. abstract rules or grammars) and specific parameters (i.e. markers, switches) that for particular languages are either turned on or off. For example, the position of heads in phrases is determined by a parameter. Whether a language is head-initial or head-final is regarded as a parameter which is either on or off for particular languages (i.
Théorie X-barre
La théorie X-barre (notée X̅) a été proposée par Noam Chomsky en 1970 dans le cadre de la linguistique générative, et développée ensuite par Ray Jackendoff (1977). Elle permet d'imposer des restrictions sur la classe des catégories grammaticales possibles tout en permettant une mise en parallèle de ces dernières grâce à des métarègles (généralisation de plusieurs règles). Par extension, cette théorie prédit des catégories grammaticales non-marquées au contraire des catégories majeures (nom, verbe, adjectif et adverbe) : déterminant (Dét.
