Cohesion and Coherence

Cohesion can be defined as the links that hold a text together and give it

meaning. The term cohesionwas introduced by Halliday and Hasan in 1976 to

denote the way in which linguistic items of which texts are constituted are

meaningfully interconnected in sequences. Each piece of text must be cohesive

with the adjacent ones for a successful communication.

There are two main types of cohesion: grammatical, referring to the

structural content, and lexical, referring to the language content of the piece and a

cohesive text is created through many different ways. In Cohesion in English,

M.A.K. Halliday and Ruqaiya Hasan identify five general categories of cohesive

devices that create coherence in texts: reference, ellipsis, substitution, lexical

cohesion, and conjunction.

Reference(realized by nouns, determiners, personal and demonstrative

pronouns or adverbs) either points out of the text to a real world item (i.e., to its

denotate), hence exophoricreference (deixis: Can you see that?), or refers to an item within the text, hence endophoricreference. The two possible directions of endophoric reference are backward (anaphoricr.; directanaphora: I met a man. He was wearing ..., indirectanaphora: It is a solid house. The walls are thick ...) or forward (cataphoricr.: ... the house whose walls are thick); in the case of a reference to an item of which there is (in the given situation) only one instance, we talk about homophora(e.g. Place the books on the table please). The relationship between two items in which both refer to the same person or thing and one stands as a linguistic antecedent of the other is called coreference(compare He saw himself in the mirror with He saw him in the mirror).

Reference (semantic level)

EXOPHORA ENDOPHORA

(situational) (textual)

ANAPHORA CATAPHORA

(referring to preceding text) (referring to following

text)

Examples:

ANAPHORA: Three blind mice see how they run.

CATAPHORA: I would never have believed it. They've accepted the proposal.

EXOPHORA: (a child making noise). Mother: Stop doing that here. I'm trying to work.

Types of reference:

a. PERSONAL – lexical items replaced with personal pronouns, possessive

adjectives, possessive pronouns …

b. DEMONSTRATIVE – realised by deictic terms: demonstrative adverbs (here,

now …), nominal demonstratives (this, these …), definite article (the).

c. COMPARATIVE – on the basis of identity (same), similarity (such),

difference (other, else), numerative (more, less), epithets (better).

Examples of types of reference:

PERSONAL: John has moved to a new house.

He had it built last year.

DEMONSTRATIVE: I like the push-ups and the sit-ups.

These are my favourites.

COMPARATIVE: Mary was a lady in mid-20s.

Such people can't change a flat tyre.

Ellipsis, i.e., omission of something referred to earlier, is an instance of

textual anaphora (e.g., Have some more). Types of ellipsis:

a. NOMINAL – a word functioning as deictic, numerative, epithet or

classifier is upgraded from the status of modifier to the status of head.

i. -Did you get a first prize? – No, I got a third.

ii. His sons went into business. Neither succeeded.

b. VERBAL – the structure does not fully express its systemic features.

i. Have you been swimming? Yes, I have. (lexical ellipsis)

ii. Has she been crying? No, laughing. (operator ellipsis)

c. CLAUSAL – clauses have a two-part structure: MODAL +

PROPOSITIONAL ELEMENTS

i. Who taught you to spell? Grandfather did.

PRESUPPOSED CLAUSE | ELLIPTICAL FORM |

SUBSTITUTION FORM | FULL FORM

ii. Has the plane landed? | Yes, it has. | Yes it has done.

| Yes, it has landed.

Substitutionis very similar to ellipsis in the effect it has on the text, and

occurs when instead of leaving a word or phrase out, as in ellipsis, it is substituted

for another, more general word. For example, "Which ice-cream would you like?"

- "I would like the pink one" where "one" is used instead of repeating "ice-cream."

Conjunction,creates cohesion by relating sentences and paragraphs to each

other by using words from the class of conjunctions or numerals. Types of

conjunction:

a. ADDITIVE (includes alternative and negative)– and, nor, or (else),

furthermore, thus, likewise …

b. ADVERSATIVE – yet, but, however, actually, instead, at any rate …

c. CAUSAL – so, hence, consequently, because, otherwise …

d. TEMPORAL – then, finally, soon, up to now, in short, to sum up …

Examples:

He was climbing for the whole day…

a. ADDITIVE: …and in all this time he met no one.

b. ADVERSATIVE: …yet he was hardly aware of being tired.

c. CAUSAL: …so by night time the valley was far bellow him

d. TEMPORAL: …then as dusk fell, he sat down to rest.

Lexical cohesionestablishes semantic (through lexical devices, such as

repetition, equivalence - synonymy, hyponymy, hyperonymy, paraphrase,

collocation) and pragmatic (presupposition) connectedness; in contrast with the

previous types of cohesion, it operates over larger stretches of text since it

establishes chains of related references.

REITERATION – the repetition of the same lexical item + the occurrence of

a related item.

There’s a boy climbing that tree.

a. Repetition

The boy’s going to fall if he doesn’t take care.

b. A synonym or near-synonym

The lad’s going to fall if he doesn’t take care.

c. A superordinate

The child’s going to fall if he doesn’t take care.

d. A general word

The idiot’s going to fall if he doesn’t take care.

REFERENCE: There’s a boy climbing that tree.

a. Identical

The boy’s going to fall if he doesn’t take care.

b. Inclusive

Those boys are always getting into mischief.

c. Exclusive

And there’s another boy standing underneath.

d. Unrelated

Most boys love climbing trees.

Coherencein linguistics is what makes a text semantically meaningful.

The notion of coherencewas introduced by Vestergaard and Schroder as a way

of talking about the relations between texts, which may or may not be indicated

by formal markers of cohesion. Beaugrande/Dressler define coherence as a

“continuity of senses” and “the mutual access and relevance within a

configuration of concepts and relations” . Coherence, as a sub-surface feature of a

text, concerns the ways in which the meanings within a text (concepts, relations

among them and their relations to the external world) are established and

developed. Some of the major relations of coherence are logical sequences, such

as cause-consequence (and so), condition-consequence (if), instrumentachievement (by), contrast (however), compatibility (and), etc. Moreover, it is the general ´aboutness´, i.e., the topicdevelopment which provides a text with necessary integrity; even in the absence of overt links, a text may be perceived as coherent (i.e., as making sense), as in various lists, charts, timetables, menus.

Coherence is present when a text makes sense because there is a continuity

of senses which holds a text together – it has to be semantically and logically OK.

George entered the room. He saw Mary cleaning the table.

John fell and broke his neck. (?) John broke his neck and fell.

Textual Categories

The textual category is a property characterizing every text, in other words,

it is a typological feature of a text. Textual categories appear and function only in

the text as a language unit of the highest rank. It is important to remember that the

text is never modeled by one textual category but always by a totality of

categories. It is sometimes regarded as a total of categories.

Today the list of textual categories is open: linguists name different textual

categories because they approach the text from different angles. Most scholars

differentiate between contensiveand structuralcategories. However, some

linguists draw a strict demarcation line between the two while others do not. The

most commonly identified textual categories include:

1) divisibility– the text can be divided into parts, chapters and paragraphs

dealing with specific topics, therefore having some formal and semantic

independence;

2) cohesion– formal connectedness;

3) coherence– internal connectedness (integrity, according to I. R.

Galperin);

4) prospection(flash-forward) – anticipation of future events;

5) retrospection(flash-back) – return to events in the past;

(Both prospection and retrospection break the space-time continuum of the

text.)

6) anthropocentricity– the Man is the central figure of any text

independent of its specific theme, message and plot;

7) conceptuality– any text has a message. Expressing some idea, that is,

conveying a message is the basis of any creative work;

8) informativity

Prof. I. R. Galperinwhose book on the text and its categories is one of the

most authoritative and often quoted ones identifies three types of information:

- content-factual information – information about facts, events and

processes taking place in the surrounding world; always explicit and verbalized;

- content-conceptual information conveys to the reader the author’s

understanding of relations between the phenomena described by means of

content-factual information, understanding of their cause-effect relations,

importance in social, economic, political and cultural life of people including

relations between individuals. This kind of information is deduced from the

whole literary work and is a creative re-understanding of these relations, facts,

events and processes; not always explicit;

- content-implicative information is hidden information that can be

deduced from content-factual information due to the ability of linguistic units to

generate associative and connotative meanings and also due to the ability of

sentences conveying factual information to acquire new meanings.

9) completeness –the text must be a complete whole;

10) modality– the attitude of the author towards what is being

communicated;

11) the author’s image –way the author’s personality is expressed in the

text.
