Word Classes

1. Word Classes Lecture 1b

2. Syntax • Syntax is how words are put together to form sentences. • There are many theories of syntax, with lots of different terminologies. We will be using the terminology used in the Grammar Survey and in Fromkin et al. • We’ll mostly concentrate on English, although we will make reference to other languages

3. Syntax • Words belong to different classes or “parts-of- speech”, like noun, verb or adjective. Let’s look at the following three groups of words: • Group 1: woman, table, dogs, morning, garden • Group 2: walk, see, hit, write, listen • Group 3: happy, blue, circular, big • How do we know which word belongs in which group or word class?

4. Notional vs Formal definitions What is a noun? • ‘a noun is a word that refers to a person, place or thing’ What is a verb? • ‘a verb is a doing word’ or ‘a verb is a word that refers to an event or state’ What is an adjective? • 'adjectives are words that refer to properties of things’

5. Notional vs Formal definitions • These definitions are meaning-based and are what are called notional definitions. • There are problems with notional definitions.

6. Problems with notional definitions • The explosion broke all the windows • The thirst was unbearable • Ponting took a great catch • We are expecting the train’s arrival What sort of words are explosion, thirst, catch and arrival in these sentences?

7. Problems with notional definitions • We want to say that they are nouns like the words in Group 1 (woman, table, dogs, morning, garden) • But do they refer to ‘a person, place or thing’? • an explosion is an event, not a thing • thirst is a state of being, not a thing • the arrival of the train is an event • a catch could be an event, or may be a thing

8. Problems with notional definitions Nouns can refer to a wide range of concepts: • physical entities (table, chair, house, stone …) • people (girl, uncle, daughter, student …) • attributes (brightness, clarity, sadness …) • mental states (confidence, love, meditation …) • abstract entities (truth, individuality, ownership…) • events (disappearance, arrival, explosion …)

9. Notional vs Formal definitions • Rather than relying on notional definitions, linguists use formal properties to decide whether a word is in a particular word class or not • Words in the same word class behave the same (are found in the same environments, have the same grammatical features).

10. Syntactic features • Distributional or combinatorial features – the position that a word occupies relative to the other words it occurs with. Example: • Nouns combine with words like the, a, this and my to form what is called a noun phrase: the dog, an explosion, this class • Adjectives combine with a following noun within a noun phrase: the clever dog, a loud explosion

11. Morphological features Associated grammatical categories Some words have variable forms which express special types of meaning or which depend on a relationship with other elements in a phrase or sentence. Example: • English nouns can get a final ‑s to show that there’s more than one of them (the grammatical category of ‘number’) dog/dogs,walk/walks • verbs can get a final ‑ed to show that the event happened in the past (the grammatical category of ‘tense’) walk/walked, paint/painted

12. Morphological features • Most English pronouns have variable forms. • The choice of form depends on the relationship between the pronoun and other words: • I saw him, He saw me (*Me saw he, *Him saw I) • In Latin, most nouns have variable forms: • Agricola nautam vidit. The farmer saw the sailor • Nauta agricolam vidit.The sailor saw the farmer.

13. Formal definitions • Formal definitions are less problematic than notional ones. • If a word behaves in a particular way, it belongs in the same word class as all the other words which behave in the same way.

14. Note: • Some English words with the same form and similar meanings can be in different classes. Example: There are two words catch in English : • Good cricketers always catch the ball. • Ricky Ponting took a great catch. These words have different formal properties: • they catch, they caught, they are catching • a great catch, several great catches.

15. Another example • The students find the work difficult • find is a verb • The archaeologists made several finds • find is a noun

16. Open word classes • We can divide words into two classes - open and closed classes. • The open word classes are ‘open’ in the sense that new words can be added into these classes. • Words in open word classes are often referred to as content words.

17. Nouns • Nouns make up one of the most important word classes in English. • This class includes words like: cat, dog, house, arrival, disappearance, John, Mary, Brisbane, linguistics, university, student

18. Morphological property of nouns • In English, many nouns have different forms depending on whether they refer to just one of the items, or more than one. Examples: • cat ~ cats, dog ~ dogs, horse ~ horses • child ~ children, goose ~ geese • The subclass of nouns that vary in this way are called count nouns. • Massnouns (sugar, snow, chalk, rice) • Propernouns (Peter, Brisbane, Queensland)

19. Syntactic properties of nouns • Nouns can occur alone in the context: DETV ____ • DETV is the abbreviation for determinative • Determinatives include words like the, a, this, these, some Examples: • the book, an apple, those elephants, some sugar • The nouns which can occur in this context are the common nouns (mass nouns and count nouns). • Proper nouns in English do not (usually) occur with articles a/the(*the Samantha, *a/the Brisbane)

20. Syntactic properties of nouns All nouns can occur alone in the context: • (DETV) ____ VERB • The parentheses mean that what it contains is optional. Examples: • The cat smells,John smokes, Water freezes, Doors open

21. Lexical verbs • Lexical verbs make up a large openclass • There are many lexical verbs in English (which we’ll discuss in detail in week 4). • Lexical verbs include words like go, come, take, run, walk, read, write,think,cook,eat, understand, and arrive.

22. Morphological property of lexical verbs Lexical verbs have an ‑ing form, an ‑s form, and a past tense form (at least). Example: the verb eat has forms eating, eats and ate Many lexical verbs (but not all) have a form in ‑ed (as in walked) or a form in ‑en (as in eaten).

23. Syntactic property of lexical verbs Lexical verbscan occur alone in the context: • MODAL NP ____ where MODAL is a type of auxiliary verb (which will be discussed shortly) like can, must, will; and NP stands for noun phrase (which we will look at in Week 2) e.g., the book, John, some sugar, cats, a big elephant.

24. Syntactic property of lexical verbs MODAL NP ____ ? Examples: • Must you go? • Can he stay? • Should we hyphenate? • Will the horses eat? • Should the students leave?

25. Adjectives • Adjectives include words like big, small, large, heavy, interesting, expensive and fast Example: a fast car, the expensive coat

26. Morphological properties of adjectives • Many adjectives inflect for grade. • Most adjectives with only one or two syllables can take the suffixes ‑er and ‑est to form the comparative (‘more’) and superlative (‘most’). Examples: • great ~ greater ~ greatest • happy ~ happier ~ happiest NOTE: Many adverbs also have this property

27. Morphological properties of adjectives • Most adjectives can take the suffix ‑ly to form an adverb. Examples: • quick ~ quickly, ready ~ readily, beautiful ~ beautifully, unconstitutional ~ unconstitutionally • The first member of these pairs is an adjective • The second is an adverb. NOTE: • This -ly must not be confused with the -ly that forms adjectives from nouns: • man ~ manly, cost ~ costly, friend ~ friendly, love ~ lovely

28. Syntactic property of adjectives Adjectives can occur alone in the context: • (DETV) NOUN is ____ Nearly all adjectives (and mass nouns) can occur in this position Examples: • This car is green • Peter is hungry • A lion is dangerous • My neighbour is happy

29. Syntactic property of adjectives Most adjectives can occur in the context DETV ____ NOUN Examples: • the big elephant, a fast car, a dangerous lion However, some nouns can also occur in this position. Examples: • the police car, the kitchen floor

30. A syntactic test which does distinguish adjectives from nouns is: • DETV ADJ NOUN • * DETV NOUN ADJ Examples: • a beautiful baby (*a baby beautiful) • the fantastic film (*the film fantastic) • this yummy meal (*this meal yummy)

31. A noun can precede or follow another noun • DETV NOUN NOUN Examples: • A corporation law • A law corporation • A prayer meeting • A morning prayer

32. Adverbs • Adverbs are words like quickly, slowly, fortunately and fast (e.g., She ran fast). • Degree adverbs form a subclass of adverbs which combine with adjectives or other adverbs Examples: very, rather, extremely and quite. verynice, rather handsome, quite slowly

33. Morphological property of adverbs • Many adverbs have the form adjective +ly, as in happily, quickly, beautifully, amazingly • Not all words ending in -ly are adverbs; when added to a noun, -ly forms an adjective, as in costly, heavenly, manly, womanly, friendly… • Some adverbs have no distinctive ending (and no related adjective), e.g., soon, just, very, less, well, worse. • Don’t rely on the traditional formal definition that “adverbs end in –ly”, this is not always the case.

34. Syntactic property of adverbs • Most adverbs can appear alone in the context: NP VERB NP ____ Examples: • The boys finished the job quickly • She did the job badly/well.

35. OPEN WORD CLASSES • noun • lexical verb • adjective • adverb

36. Closed word classes • Closed word classes are ‘closed’ in that they do not easily accept new members, and most of them are quite small, so that it is possible to exhaustively list all the members of the class. • Unlike with the open word classes, there is often variation in the terms and classifications used in talking about closed word classes, and different languages have different closed word classes.

37. Closed class words: • Pronouns • Determinatives/determiner • Prepositions • Auxiliary Verbs • Coordinators / conjunctions • Subordinators / complementisers

38. Pronouns We will talk about three different types of pronouns: • personal pronouns • interrogative pronouns • relative pronouns. (Traditional grammar also talks about demonstrative pronouns and indefinite pronouns, but we will not use these terms.)

39. Personal pronouns Personal pronouns have different forms for: • person (first, second, third): I, you, he/she • number (singular, plural): I, we • case (nominative, accusative, dependent genitive, independent genitive and reflexive): I, me, my, mine, myself • The forms of the personal pronouns in standard English are listed on page 5 of your lecture notes 1B.

40. Interrogative pronouns • Interrogative pronouns: • who, whose, whomfor humans • what for non-humans • We use these forms to ask about someone or something: • Who said that? What happened? Whose book?

41. Relative pronouns • Relative pronouns areused within a noun phrase in constructions like: • the woman who took the car • the woman whose book you borrowed • the man whom you interviewed • the tree which fell • a pub where we met • that time when you fainted • one reason why they left

42. Determinatives/determiners • Determinatives usually indicate whether the speaker has a particular individual in mind or whether they assume that the addressee can – or cannot – identify what is being referred to: • the, this, each, every, a, some, any … • The most important members of the class of determinatives are the (definite article) and a/an (indefinite article).

43. Syntactic property of Determinatives • Determinatives occur as the first word in a noun phrase: • the happy boy • those new books • a dirty face • some fast cars • many new books • several unhappy people • various brave and hearty students

44. Types of Determinatives • There are quite a few determinatives, and they can be sub-classified according to the kinds of meanings they express. • The major determinatives are: • Article: the, a, an • The student came to class. • Demonstrative: this, these, that, those • That student came to class.

45. More Determinatives Universal: all, both • Both students came to class. Distributive: each, every • Every student came to class. Existential: some, any • Some students came to class. Cardinal numerals: one, two, three, etc. • Three students came to class.

46. Determinatives Disjunctive: either, neither • Neither student came to class. Negative: no • No student came to class. Additive: another • Another student came to class. Degree: many, more, few, little • Few students came to class. Sufficiency: enough, sufficient • Enough students came to class.

47. Prepositions • Traditionally, the notional definition of prepositions has to do with space and time, and the traditional formal definition is that it occurs before a noun phrase: • in the box, on the sofa, at 3 o’clock, before dawn • Prepositions in English are morphologically invariable (that is, they do not change form). This means we’ll have to concentrate on their syntactic properties to define them.

48. Syntactic Properties of Prepositions • ____ NP • He was standing outside the house • The horse jumpedover the fence • He ranfrom the burning building. • Joseph cameafter the party. • Some prepositions can stand alone without a following NP • He was standing outside • The horse jumpedover • Joseph cameafter • * He ranfrom

49. Syntactic Properties of Prepositions • Some prepositions precede other prepositions: • ____ P + NP • He crawled out from behind the sofa • He looked over from the house • She took it offof the table. (American English) • She threw it out of the window. • She stole it from under his nose.

50. Syntactic Properties of Prepositions • Most prepositions can be modified by right Examples: • He was standing RIGHToutside the house • The horse jumped RIGHT over the fence • He ran RIGHT from the burning building. • Joseph cameRIGHTafter the party.
