SEMANTICS
PRAGMATICS
Phonology looks at and describes the sound system
of a language.
Morphology looks at the way words are formed .
Syntax describes the way words fit together to form
sentences or utterances.
Semantics study meaning.

Semantics study meaning.
Pragmatics study usage.
Syntax
• Syntax: is the branch of
linguistics deals with sentence
structure.
• In order to study the structure of • In order to study the structure of
sentences, we have to know the
grammatical rules governing the
way words are combined to form

rules
phrase structure rules
To understand the language in terms of syntactic rules, we
have to know what are the SYNTACTIC CATEGORIES!
A syntactic category is either a phrasal category, such as
noun phrase or verb phrase, which can be decomposed into
smaller syntactic categories, or a lexical category, such as
noun or verb, which cannot be further decomposed.
SYNTACTIC CATEGORIES

noun or verb, which cannot be further decomposed.
The three criteria used in defining syntactic categories are:
1. The type of meaning it expresses.
2. The type of affixes it takes.
3. The structure in which it occurs.
A family of expressions that can substitute for one another without loss of grammaticality is called a syntactic category.
1. The cat chases the mouse.
2. The dog chases the mouse2. The dog chases the mouse
3. The policeman chases the mouse.
4. The mother mouse chases the mouse.
If words and phrases could not be assigned to a small group of categories, it would be very hard to learn or use a language.
Dr. Shadia Yousef Banjar 9
– In the given examples: 1-4,
– every word is a member of a category.
– a word’s category type determines the
kind of phrase it can form.
– a phrase is a word or string of words that functions as a unit in a sentence,
built around a head.built around a head.
– Every language has specific phrase
structure rules determining how phrasescan be combined to form sentences.

CATEGORIES
�Lexical word categories are:
� Words that have some sort of inherent meaning
are called lexical words (or content words).
� Categories pertaining to such words are called
lexical categories e.g. NOUN, VERB, ADJECTIVE.
Open-class in the sense that new words can be
LEXICAL WORD CATEGORIES
Dr. Shadia Yousef Banjar 12
�Open-class in the sense that new words can be
added, and thus have a large number of class
members.
Functional word categories are:
� Words that don’t have (an easily detectable) inherent
meaning are called functional words because such words
perform some function in the sentence.
�Categories belong to such words are called FUNCTIONAL
CATEGORIES e.g. DETERMINER, CONJUNCTION
Functional word categories
Dr. Shadia Yousef Banjar 13
CATEGORIES e.g. DETERMINER, CONJUNCTION
� Functional word categories tend to be CLOSED-CLASS
(new words may not be added) and have a small number of
class members.
Morphological properties
� it can take a plural -s morpheme;
Exceptions: children, deer, mice, fish, . . .
�it can be modified by a possessive (apostrophe: ’s)
� it contains morphemes like the following: -ity, -ness,
NOUN
Dr. Shadia Yousef Banjar 14
� it contains morphemes like the following: -ity, -ness,
-action, -er, -ion, -ment, -ance, -hood.
These are all NOUN- OR NOMINAL SUFFIXES e.g
friendliness, writer, government, neighborhood.
Syntactic properties of the class of NOUN
• preceded by articles like: the, demonstrative
pronouns like: this, that, these, those and
numerals like: one, two, three.
•preceded by an ADJECTIVE or several
Dr. Shadia Yousef Banjar 15
•preceded by an ADJECTIVE or several
ADJECTIVES.
•followed by a PREPOSITION.
•preceded by a PREPOSITION.
Morphological properties
• takes a past tense –ed1 form e.g. He walked.
• takes the –s form of the verb for third-person
singular agreement e.g. He goes to work daily.
• takes the –ing form to express the
Verb
Dr. Shadia Yousef Banjar 16
• takes the –ing form to express the
progressive aspect e.g. he is running.
• takes the –ed2 form to express the perfective
aspect e.g. I have finished my work.
Syntactic properties of the class of VERB
• preceded by AUXILIARIES. These are words
like do and have e.g. has come, does like.
•preceded by MODAL VERBS. These are words
like can, must, will and should e.g. can
cook, must work, will sleep, and should eat.
Dr. Shadia Yousef Banjar 17
•preceded by negation words like not and
never e.g. not cry, never shouts.
• preceded by an ADVERB or ADVERBS e.g.
quickly run.
• can be followed by a NOUN e.g. hate John.
Morphological properties
• has morphemes like -ous, -y, -ish, e.g. furious,
angry, brownish, friendly.
•able to form comparatives and superlatives with -er
ADJECTIVE
Dr. Shadia Yousef Banjar 18
•able to form comparatives and superlatives with -er
and -est. e.g. bigger , biggest.
Syntactic properties
• can be preceded by ADVERBS e.g. very
angry, more hard-working.
•can occur after determiners like the, a, this,
these, those and numerals and before
NOUNS e.g. the angry boy, those twelve small
Dr. Shadia Yousef Banjar 19
NOUNS e.g. the angry boy, those twelve small
monkeys.
• modifies a NOUN.
•cannot immediately follow PREPOSITIONS
e.g. *in angry.
•can follow VERBS. E.g. He is angry.
XXXXXXX
Morphological properties
• often followed by the morpheme –ly, e.g. swiftly,
quickly, angrily.
Exceptions: abroad, now, fast, often, well, also, very,
too, never, so, ...
Syntactic properties
ADVERB
Dr. Shadia Yousef Banjar 20
Syntactic properties
• modifies a VERB; e.g. walks quickly.
•modifies an ADJECTIVE; e.g. swiftly angry.
•modifies another ADVERB; e.g. very angrily.
Constituents
A constituent is a grammatical unit which is part of a larger grammatical unit.
in example (1):
• The cat = noun phrase
• Noun Phrase =determiner + noun
Dr. Shadia Yousef Banjar 21
• Noun Phrase =determiner + noun
• "determiner" and "noun“ are the constituents of the noun phrase.
Three aspects of a speaker’s syntactic
knowledge are explicitly represented in tree
diagrams:
1. The linear order of the words in the
sentence,

sentence,
2. the groupings of words into syntactic
categories, and
3. the hierarchical structure of the syntactic
categories.

•Words can be grouped in certain patterns to
form sentences.
•In terms of forms, a sentence consists of a
noun phrase and a verb phrase.
•In terms of function, a sentence consists of a
Form and Function
Dr. Shadia Yousef Banjar 24
•In terms of function, a sentence consists of a
subject and a predicate. A predicate must contain
a predicator which is a verb.
•The class of a constituent indicates its form
and what the form does or act as a grammatical
unit indicates its function.
