1. Goals of Linguistic Theory (cf. Van Valin & LaPolla 1997)
- Describing linguistic phenomena (passive sentences, wh-questions, etc.)
- Explaining linguistic phenomena
- Understanding the cognitive basis of language (processing, knowledge, acquisition)
- Inductive vs. Deductive theories (inductive: data ---> hypothesis, deductive: hypothesis ---> data)
- Types of explanation criteria (economy: simplicity, motivation: independent evidence, predictiveness: broader coverage even unseen data)
2. Levels of Adequacy in Linguistic Theory (cf. Chomsky 1965, Dik 1978, 1991)
- Observational adequacy: a grammar can accept or reject a sentence
- Descriptive adequacy: assigning structures to sentences that match native speakers' intuition about structure and meaning
- Explanatory adequacy: can explain how the facts are the way they are and how they arise in the mind og the speaker and hearers
- Psychological adequacy (acquisition, processing, production, interpretation, etc.)
- Pragmatic adequacy (compatible with a pragmatic theory of verbal communication)
- Typological adequacy
3. Linguistic Competence vs. Performance (cf. Chomsky 1965)
I-language vs. E-language (cf. Chomsky 1986)
- Linguistic competence is a native speaker's knowledge of language
- Linguistic Performance is the actual use of language on particular occasions.
- E(xternal)-language corresponds roughly to the pretheoretical idea of what a language is. It consists of the overt phenomena of linguistic interaction in the social-cultural realm.
- I(nternal)-language (the grammar) is an abstract object accessible only through native speakers' intuitions, and in this view, only I-language falls within the scope of linguistic study. Thus, linguistics is the science of grammar, not of language.
- Universals are generalizations about I-languages, e.g. properties of grammars; they are not about E-languages, e.g. properties of languages.
4. Infinite Rule-governed Creativity
- Finite number of rules, but infinite number of sentences
- Recursive rules
- examples: NP ---> Det N PP, PP ---> P NP, VP ---> V NP InfP, InfP ---> to VP, etc.
5. Principles and Parameters (cf. Haegeman 1994)
- Principles in Universal Grammar (UG) refer to absolute universals and notions that do not vary from one language to the next, e.g. Empty Category Principle (ECP), (Extended) Projection Principle.
- Parameters in UG refer to language-specific properties which are not fully determined by UG but which vary cross-linguistically, and for these properties a range of choices is made available by UG, the pro-drop parameter, head-final/head-initial parameter.
- Some principle can also be parameterized, e.g. Subjacency Principle can have a parameter for the bounding node which is S for English but S-bar for French.
6. Levels of Syntactic Representation
