Extended projection principle
The extended projection principle (EPP) is a linguistic hypothesis about subjects. It was proposed by Noam Chomsky as an addendum to the projection principle. The basic idea of the EPP is that clauses must contain a noun phrase or determiner phrase in the subject position (i.e. in the specifier of a tense phrase or inflectional phrase or in the specifier of a verb phrase in languages in which subjects don't raise to TP/IP, e.g. Welsh). Most verbs require meaningful subjects—for example, "kick" in "Tom kicked the ball" takes the subject "Tom".
Complementizer
In linguistics (especially generative grammar), a complementizer or complementiser (glossing abbreviation: ) is a (part of speech) that includes those words that can be used to turn a clause into the subject or object of a sentence. For example, the word that may be called a complementizer in English sentences like Mary believes that it is raining. The concept of complementizers is specific to certain modern grammatical theories. In traditional grammar, such words are normally considered conjunctions.
Finite verb
Traditionally, a finite verb (from fīnītus, past participle of fīnīre - to put an end to, bound, limit) is the form "to which number and person appertain", in other words, those inflected for number and person. Verbs were originally said to be finite if their form limited the possible person and number of the subject. A more recent concept treats a finite verb as any verb that heads a simple declarative sentence. Under that newer articulation, finite verbs often constitute the locus of grammatical information regarding gender, person, number, tense, aspect, mood, and voice.
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.
