Resulting Theory of GrammarWords, phrases, categories for words and phrases (e.g. nouns, verbs, noun phrases, verb phrases)

(basic concepts any theory of grammar must have in order to capture the data)

1) Every word belongs to a lexical category

2) Lexical categories forms heads of phrases

3) How phrases are formed is governed by rules (= „phrase structure rules‟)

Rules that determine…

what goes into a phrase („constituents‟)

how the constituents are orderedConstituent: a word or group of words that

function as a unit and can make up largergrammatical units

The component that determines the propertiesof the constituent is the head, and theconstituent can be referred to as a phrase: e.g.noun phrase“noun phrases have a Det and a N”NP Det N

1. S NP VP

2. NP {Det N, Pro, PN}

3. VP V (NP) (PP) (Adv)
