Components of the grammar: phonetics,
phonology, morphology, syntax, semantics
Syntax – rules for combining words to form
sentences or relations that hold between the
elements of a sentence.
Grammatical sentence: any utterance judged by a
native speaker as well-formed.
Ungrammatical sentence: an ill-formed sentence
that is unlikely to be ever generated by a native
speaker
Transformational syntax – the most popular
approach to syntactic analysis

Transformational syntax – rules
specifying how
tree structures can be
modified by moving an element from
one position to another
Word-level categories
Word-level categories
Lexical categories – have a dictionary
meaning:
Verb – arrive, love, smile, kick,
Noun – boy, table, dogs, loyalty,
bravery
Adjective – nice, funny, ridiculous,
Adverbs – beautifully, carefully, fast,
hard
Word-level categories
Word-level categories
Non-lexical categories – do not usually have a
dictionary meaning:
Determiner: the, a, an, this, those
Degree word: too, so, very, more, quite
Qualifier: always, perhaps, almost, often
Auxiliary: will, have, do, should, might
Conjunction: and, but, or
!!! Some words belong to two different
categories, e.g. work, walk, hard, fast, near,
etc.

category
category
Meaning – nouns name entities, verbs name
actions, adjectives desribe certain properties of
nouns, adverbs describe how actions are
performed
Distribution: nouns appear with determiners (the
book), verbs with an auxiliary (will see), adjectives
with a degree word (very rich)
Inflection:
nouns - the plural suffix –s: books, cars
verbs – the past suffix –ed: watched, looked
the progressive – ing: watching
adjectives – comparative suffixes –er, -est: taller,
tallest
Phrases
Phrases
The man is good to the baby
Det N V A P Det N
Sentence structure
S → Det N V A P Det N
Almost any sequence of category types are possible:
N, A (the best thing imaginable)
A, N (such a kind girl)
V, P (I look into your eyes)
P, V (the man you are waiting for has called)
A, P (living is easy with eyes closed)
V, N (I’ll never lose affection)
N, V (Moscow girls make me sigh)
Certain groups of words tend to occur in the same positions,
e.g. Det N, Aux V. Such strings of words are referred to as
phrases.

Phrase structure
Phrase structure
Phrases and sentences are not formed by stringing
words together:
John doesn’t like his uncle.
*like doesn’t John uncle his
Inflectional languages are more flexible in this respect:
Rdza zżera stare żelazko vs. Żelazko stare zżera rdza.
* Stare rdza zżera żelazko.
The word around which a phrase is built is called the
head.
NP, VP, AP, PP
Phrases don’t normally contain one word, e.g. the bird

Specifiers
Specifiers
Specifiers make the meaning of the head more
precise:
the boy – the indicates that the speaker has a
specific boy in mind
Never drinks coffee – never indicates non-
occurring event
Quite nice – quite shows the extent to which a
given property is manifested
In English specifiers are always located to the
left of the head
Complements
Complements
Complements provide information
about entities and locations whose
existence is implied by the meaning of
the head, e.g.
[NP the books about the war]
[VP never drinks coffee with milk]
[AP quite sure about Luke’s innocence]
[PP almost ready to become president]

Phrase structure rules
Phrase structure rules
Phrase structure rules stipulate, i.e.
state, the position of specifiers,
heads and complements in phrases.
NP → (Det) N (PP) ...
VP → (Qual) V (NP) ...
AP → (Deg) A (PP) ...
PP → (Deg) P (NP) ...
Sentence structure
Sentence structure
Sentence – the largest unit of syntactic
analysis.
Sentences usually consist of a NP combined
with a VP.
The young scientist invented a mobile
phone.
It is assumed that sentences have as their
head an abstract category called inflection,
which indicates the sentence’s tense.

Tests for phrase structure
Tests for phrase structure
The substitution test:
[The guests] left after [they] had been
cheated.
The movement test:
There is a lamp [on the table] vs. [On the
table], there is a lamp.
The coordination test:
The children [often sweep the floor] but
[never make the bed].
Transformations
Transformations
Transformations – various
syntactic operations performed to
make questions.
Basic operations include:
inversion in yes-no questions,
wh-movement,
