INTRODUCTION
The model of immediate constituents is based on the group-parsing
of the sentence which has been developed by traditional grammar together with
the sentence-part parsing scheme. It consists in dividing the whole of the
sentence into two groups: that of the subject and that of the predicate, which,
in their turn, are divided into their sub-group constituents according to the
successive subordinative order of the latter. Profiting by this type of
analysis, the IC-model explicitly exposes the binary hierarchical principle of
subordinative connections, showing the whole structure of the sentence as made
up by binary immediate constituents. As for equipotent (coordinative)
connections, these are, naturally, non-binary, but, being of a more primitive character
than subordinative connections, they are included in the analysis as possible inner
subdivisions of subordinative connections [1].
THE IC METHOD (METHOD OF IMMEDIATE CONSTITUENTS)
This method was elaborated by the
head of American Descriptive Linguistics Leonard Bloomfield.The IC method aims
at describing any complex form ranging from long sentences to multi-element
words in terms of their constituents. The form is divided into two parts, the
remaining parts are also divided into parts until ultimate indivisible pieces
are arrived at un][gent]le][man][ly. The main requirement on the
morphological level is that ultimate constituents (or at least one of them)
should be recognizable as morphemes: book||let; let is a
diminutive suffix. The word ham||let (a small village) can also be
divided into 2 parts , though we do not know what ham here means.
Proceeding from the intuition of a
native speaker, L.Bloomfield analyzed the sentence Poor John ran away
in the following way Poor ][ John// ran ][ away.
The main requirement of the method on
the syntactical level is that ultimate constituents should be words [2].
There are several varieties of
diagramming of this analysis. We can represent the candelabra division (1) and
the derivation tree division (2).

refers to the noun rain, but the diagram doesn’t show it..
The method shows the derivation of a
sentence, but it’s formalized, mechanistic, it disregards meanings and can’t be
employed to analyze polysemy, homonymy, ambiguity, implicit syntactic
relations, syncretism.
The IC method,
introduced by American descriptivists, presents the sentence not as a linear
succession of words but as a hierarchy of its ICs, as a ’structure of
structures’.
Ch. Fries, who further
developed the method proposed by L.Bloomfield, suggested the following diagram
for the analysis of the sentence which also brings forth the mechanism of
generating sentences: the largest IC of a simple sentence are the NP (noun
phrase) and the VP (verb phrase), and they are further divided if their
structure allows.

The deeper the layer of the phrase
(the greater its number), the smaller the phrase, and the smaller its ICs. The
resulting units (elements) are called ultimate constituents (on the level of
syntax they are words). If the sentence is complex, the largest ICs are the
sentences included into the complex construction.
The diagram may be drawn somewhat
differently without changing its principle of analysis. This new diagram is
called a ‘candelabra’ diagram.
The man hit the ball.

If we turn the analytical
(‘candelabra’) diagram upside down we get a new diagram which is called a
‘derivation tree’, because it is fit not only to analyze sentences, but shows
how a sentence is derived, or generated, from the ICs.
IC-MODEL OF THE SENTENCE
In
linguistics, immediate constituent
analysis or IC analysis is a method of
sentence analysis that was first mentioned by
Leonard Bloomfield and developed further by Rulon Wells. The process reached a full blown
strategy for analyzing sentence structure in the early works of Noam Chomsky. The practice is now widespread. Most
tree structures employed to represent the syntactic structure of sentences are
products of some form of IC-analysis. The process and result of IC-analysis
can, however, vary greatly based upon whether one chooses the constituency
relation of phrase structure grammars (constituency grammars) or the dependency
relation of dependency grammars as the underlying principle that organizes constituents into hierarchical structures.
IC-analysis divides up a sentence into major parts or immediate
constituents, and these constituents are in turn divided into further immediate
constituents. The process
continues until irreducible constituents are reached, i.e., until each
constituent consists of only a word or a meaningful part of a word. The end
result of IC-analysis is often presented in a visual diagrammatic form that
reveals the hierarchical immediate constituent structure of the sentence at
hand. These diagrams are
usually trees. For
example:
This tree illustrates the manner in which the entire sentence is
divided first into the two immediate constituents this tree and illustrates
IC-analysis according to the constituency relation; these two constituents
are further divided into the immediate constituents this and tree,
and illustrates IC-analysis and according
to the constituency relation; and so on.
An important aspect of IC-analysis in phrase structure grammars is
that each individual word is a constituent by definition. The process of
IC-analysis always ends when the smallest constituents are reached, which are
often words (although the analysis can also be extended into the words to
acknowledge the manner in which words are structured). The process is, however,
much different in dependency grammars, since many individual words do not end
up as constituents in dependency grammars.
IC-analysis
is much different in dependency grammars. Since
dependency grammars view the finite verb as the root of all sentence structure,
they cannot and do not acknowledge the initial binary subject-predicate division of the clause associated with phrase
structure grammars. What this means for the general understanding of
constituent structure is that dependency grammars do not acknowledge a finite verb phrase (VP) constituent and many individual words also do
not qualify as constituents, which means in turn that they will not show up as
constituents in the IC-analysis. Thus in the example sentence This tree illustrates IC-analysis
according to the dependency relation, many of the phrase structure grammar
constituents do not qualify as dependency grammar constituents:
Dependency
grammar (DG) is a
class of modern syntactic theories that are all based on the dependency
relation and that can be traced back primarily to the work of Lucien Tesnière. The dependency relation views the (finite) verb
as the structural center of all clause structure. All other syntactic units
(e.g. words) are either directly or indirectly dependent on the verb. DGs are
distinct from phrase structure grammars (= constituency grammars), since DGs lack phrasal
nodes. Structure is determined by the relation between a word (a head) and its
dependents. Dependency structures are flatter than constituency structures in
part because they lack a finite verb phrase constituent, and they are thus well suited for the analysis
of languages with free word order.
The
IC-analysis for a given sentence is arrived at usually by way of constituency tests. Constituency tests (e.g. topicalization, clefting, pseudoclefting, pro-form substitution, answer ellipsis, passivization, omission, coordination, etc.) identify the constituents, large and
small, of English sentences. Two illustrations of the manner in which
constituency tests deliver clues about constituent structure and thus about the
correct IC-analysis of a given sentence are now given. Consider the phrase The girl in the following trees:
The acronym
BPS stands for "bare phrase structure", which is an indication that
the words are used as the node labels in the tree. Again, focusing on the
phrase The girl, the tests unanimously confirm that it is a
constituent as both trees show:
...the girl is
happy - Topicalization (invalid test because test constituent is already
at front of sentence)
It is the
girl who is happy. - Clefting
(The one)Who
is happy is the girl. - Pseudoclefting
She is happy. - Pro-form substitution
Who is happy?
-The girl. - Answer ellipsis
Based on
these results, one can safely assume that the noun phrase The girl in
the example sentence is a constituent and should therefore be shown as one in
the corresponding IC-representation, which it is in both trees. Consider next
what these tests tell us about the verb string is happy:
*...is happy,
the girl. - Topicalization
*It is is
happy that the girl. - Clefting
*What the
girl is is happy. - Pseudoclefting
*The
girl so/that/did that. - Pro-form substitution
What is the
girl? -*Is happy. - Answer ellipsis
The star *
indicates that the sentence is bad (i.e. it is not acceptable English). Based
on data like these, one might conclude that the finite verb string is
happy in the example sentence is not a constituent and should
therefore not be shown as a constituent in the corresponding IC-representation.
Hence this result supports the IC-analysis in the dependency tree over the one
in the constituency tree, since the dependency tree does not view is
happy as a constituent.
In syntactic analysis, a constituent is a word or a group of words that
functions as a single unit within a hierarchical structure. The analysis of
constituent structure is associated mainly withphrase structure grammars, although dependency grammars also allow sentence structure to be broken down
into constituent parts. The constituent structure of sentences is identified
usingconstituency tests. These tests manipulate some portion of a
sentence and based on the result, clues are delivered about the immediate constituent structure of the sentence. Many constituents are phrases. A phrase is a sequence of two or more words
built around a head lexical item and working as a unit within a sentence. A word sequence is
shown to be a phrase/constituent if it exhibits one or more of the behaviors
discussed below.
Constituency
tests are diagnostics employed to identify the constituent structure of
sentences. There are numerous
constituency tests applied to English sentences, many of which are listed here:
1. topicalization (fronting)
2. clefting
3.
pseudoclefting
4.
pro-form substitution (replacement)
5. answer ellipsis (question test),
6.
passivization
7.
omission (deletion)
8. coordination, etc.
These
tests are rough-and-ready tools that grammarians employ to reveal clues about
syntactic structure. A word of caution is warranted when employing these tests,
since they often deliver contradictory results. Some syntacticians even arrange
the tests on a scale of reliability, with less-reliable tests treated as useful
to confirm constituency though not sufficient on their own. Failing to pass a
single test does not mean that the unit is not a constituent, and conversely,
passing a single test does not mean necessarily that the unit is a constituent.
It is best to apply as many tests as possible to a given unit in order to prove
or to rule out its status as a constituent [7].
Topicalization involves moving the test sequence to the front of the
sentence. It is a simple movement operation:
He is going to attend another
course to improve his English.
To improve his English, he is going to attend another course.
Clefting involves placing a sequence of words X within the structure
beginning with It is/was: It was X that...
She bought a pair of
gloves with silk embroidery.
It was a pair of gloves
with silk embroidery that she bought.
Pseudoclefting
(also preposing) is similar to clefting in that it puts emphasis on a
certain phrase in a sentence. It involves inserting a sequence of words
before is/are what or is/are who:
She bought a pair of
gloves with silk embroidery.
A pair of gloves with silk
embroidery is what she bought.
Pro-form substitution, or replacement, involves replacing the test
constituent with the appropriate pro-form (e.g. pronoun). Substitution normally
involves using a definite pro-form like it, he, there,here,
etc. in place of a phrase or a clause. If such a change yields a grammatical
sentence where the general structure has not been altered, then the test
sequence is a constituent:
I don't know the man who
is sleeping in the car.
*I don't know him who is
sleeping in the car. (ungrammatical)
I don't know him.
The
ungrammaticality of the first changed version and the grammaticality of the second one demonstrates that the whole
sequence, the man who is sleeping in the car, and not just the
man is a constituent functioning as a unit.
The answer ellipsis test refers to the ability of a sequence of words to stand
alone as a reply to a question. It is often used to test the constituency of a
verbal phrase but can also be applied to other phrases:
What did you do yesterday?
- Worked on my new project.
What did you do yesterday?
- *Worked on. (unacceptable, so worked on is not a
constituent).
Linguists do
not agree whether passing the answer ellipsis test is sufficient, though at a
minimum they agree that it can help confirm the results of another constituency
test.
Omission
checks whether a sequence of words can be omitted without influencing the
grammaticality of the sentence — in most cases, local or temporal adverbials
can be safely omitted and thus qualify as constituents [6].
Fred relaxes at night on
his couch.
Fred relaxes on his couch.
Fred relaxes at night.
Since they
can be omitted, the prepositional phrases at night and on
his couch are constituents.
Passivization
involves changing an active sentence to a passive sentence, or vice versa.
The object of the active sentence is changed to the subject of the corresponding passive sentence:
A car driving at breakneck
speed nearly hit the little dog.
The little dog was nearly hit by a car driving at breakneck speed.
In case passivization
results in a grammatical sentence, the phrases that have been moved can be
regarded as constituents.
The coordination test assumes that
only constituents can be coordinated, i.e., joined by means of a coordinator
such as and:
He enjoys [writing
sentences] and [reading them].
[He enjoys writing] and [she enjoys reading] sentences.
[He enjoys] but [she hates] writing sentences.
Based on the
fact that writing sentences and reading them are
coordinated using and, one can conclude that they are constituents.
The validity of the coordination test is challenged by additional data,
however. The latter two sentences, which are instances of so-called right
node raising, suggest that the sequences
in bold should be understood as constituents. Most grammars do not view
sequences such as He enjoys to the exclusion of the VP writing
sentences as a constituent. Thus while the coordination test is widely
employed as a diagnostic for constituent structure, it is faced with major
difficulties and is therefore perhaps the least reliable of all the tests
mentioned [5].
Structured by the IC-model, the cited sentence on the upper level
of analysis is looked upon as a united whole (the accepted symbol S); on the
next lower level it is divided into two maximal constituents — the subject noun-phrase
(NP-subj) and the predicate verb-phrase (VP-pred); on the next lower level the
subject noun-phrase is divided into the determiner (det) and the rest of the
phrase to which it semantically refers (NP), while the predicate noun-phrase is
divided into the adverbial (DP, in this case simply D) and the rest of the
verb-phrase to which it semantically refers; the next level-stages of analysis
include the division of the first noun-phrase into its adjective-attribute
constituent (AP, in this case A) and the noun constituent (N), and correspondingly,
the division of the verb-phrase into its verb constituent (V or Vf — finite verb) and object
noun-phrase constituent (NP-obj), the latter being, finally, divided into the
preposition constituent (prp) and noun constituent (N). As we see, the process
of syntactic IC-analysis continues until the word-level of the sentence is
reached, the words being looked upon as the "ultimate" constituents
of the sentence.
The IC model is a
complete and exact theory but its sphere of application is limited to generating
only simple sentences. It also has some demerits which make it less strong than
transformational models, for instance, in case of the
infinitive which is a tricky thing in English.
(a) The
oppositional method of analysis was introduced by the Prague School. It is
especially suitable for describing morphological categories. The most general
case is that of the general system of tense-forms of the English verb. In the
binary opposition ‘present::past’ the second member is characterized by
specific formal features – either the suffix -ed, or a phonemic modification of
the root. The past is thus a marked member of the opposition as against the
present, which is unmarked [4].
The obvious opposition
within the category of voice is that between active and passive; the passive
voice is the marked member of the opposition: its characteristic is the pattern
'be+Participle II', whereas the active voice is unmarked.
(b) The
transformational method of analysis was introduced by American descriptivists
Z.Harris and N.Chomsky. It deals with the deep structure of the utterance which
is the sphere of covert (concealed) syntactic relations, as opposed to the
surface structure which is the sphere of overt relations that manifest
themselves through the form of single sentences. For example: John ran. She
wrote a letter.
But: 1) She made him a
good wife.
2) She made him a good
husband.
The surface structures
of these two sentences are identical but the syntactic meanings are different,
and it is only with the help of certain changes (transformations) that the
covert relations are brought out:
1)
She became a good wife for him.
2)
He became a good husband because she made
him one.
The transformational
sentence model is, in fact, the extension of the linguistic notion of
derivation to the syntactic level which presupposes setting off the so-called
‘basic’ or ‘kernel’ structures and their transforms, i.e. sentence-structures
derived from the basic ones according to the transformational rules.
E.g. He wrote a letter. –
The letter was written by him.
This analysis helps one
to find out difference in meaning when no other method can give results, it
appears strong enough in some structures with the infinitive in which the ICs
are the same:
1)
John is easy to please.
2)
John is eager to please.
1) It is easy - - It is
easy (for smb.) to please John
Smb. pleases John - -
John is easy to please.
2)
John is eager - -
John
is eager to please.
John pleases smb. - -
(c)
The componential analysis
belongs to the sphere of traditional grammar and essentially consists of
‘parsing’, i.e. sentence-member analysis that is often based on the
distributional qualities of different parts of speech, which sometimes leads to
confusion.
E.g. My friend
received a letter yesterday. (A+S+P+O+AM)
His task is to watch.
(A+S+V)
His task is to settle all
matters. (A+S+V+A+O)
The described model of immediate constituents has two basic
versions. The first is known as the "analytical IC-diagrarn", the
second, as the "IС-derivation tree". The
analytical IC-diagram commonly shows the groupings of sentence constituents by
means of vertical and horizontal lines.

CONCLUSION
Building up the
"model of immediate constituents" is a particular kind of analysis
which consists in dividing the sentence into two groups: the subject group and
the predicate group, which, in their turn, are divided into their subgroup
constituents according to the successive subordinative order of the constituents.
The main advantage of the IC-model is that it exposes the binary hierarchical
principle of subordinative connection. The widely used version of the IC-model
is the "IC-derivation tree". It shows the groupings of sentence
constituents by means of branching nodes: the nodes symbolize phrase-categories
as unities, while the branches mark their division into constituents.
