Cohesion is the grammatical and lexical relationship within a text or sentence. Cohesion can be defined as the links that hold a text together and give it meaning. It is related to the broader concept of coherence

There are two main types of cohesion: grammatical, referring to the structural content, and lexical, referring to the language content of the piece. A cohesive text is created in 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.

[edit] Referencing

There are three referential devices that can create cohesion:

• Anaphoric reference occurs when the writer refers back to someone or something that has been previously identified, to avoid repetition. Some examples: replacing "the taxi driver" with the pronoun "he" or "two girls" with "they". Another example can be found in formulas such as "as stated previously" or "the aforementioned".

• Cataphoric reference is the opposite of anaphora: a reference forward as opposed to backward in the discourse. Something is introduced in the abstract before it is identified. For example: "Here he comes, our award-winning host... it's John Doe!" Cataphoric references can also be found in written text, for example "see page 10".

• Exophoric reference is used to describe generics or abstracts without ever identifying them (in contrast to anaphora and cataphora, which do identify the entity and thus are forms of endophora): e.g. rather than introduce a concept, the writer refers to it by a generic word such as "everything". The prefix "exo" means "outside", and the persons or events referred to in this manner will never be identified by the writer.

[edit] Ellipsis

Ellipsis is another cohesive device. It happens when, after a more specific mention, words are omitted when the phrase needs to be repeated.

A simple conversational example:

 A: Where are you going? B: To town. 

The full form of B's reply would be: "I am going to town".

A simple written example:

 The younger child was very outgoing, the older much more reserved. 

The omitted words from the second clause are "child" and "was".

[edit] Substitution

A word is not omitted, as in ellipsis, but 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." This works in a similar way to pronouns, which replace the noun. For example, 'Ice-cream' is a noun, and its pronoun could be 'It'. 'I dropped the ice-cream because it was dirty'. - Replacing the noun for a pronoun. "I dropped the green ice-cream. It was the only one I had'. - the second sentence contains the pronoun (It), and the substitution (one). One should not mix up the two because they both serve different purposes: one to link back and one to replace.

[edit] Lexical cohesion

Lexical cohesion is basically created by repetition (reiteration) of the same lexeme, or general nouns (super-ordinates, for example - public transport), or other lexemes sharing the majority of semantic features (also called hyponyms): The bus ... - the subway... - the tram....

Lexical cohesion can also form relational patterns in text in a way that links sentences to create an overall feature of coherence with the audience, sometimes overlapping with other cohesion features. The understanding of how the content of sentences is linked helps to identify the central information in texts by means of a possible summary. This allows judgements on what the text is about.

[edit] Conjunction

Conjunction creates cohesion using conjunctive words -- whether temporal (after,before/first, second, third), causal (because), coordinating (and), adversative (but, however), additive (further) or discourse markers (now, well, after all).

[edit] Grammatical cohesion

In linguistics, grammar refers to the logical and structural rules that govern the composition of sentences, phrases, and words in any given natural language. The term refers also to the study of such rules, and this field includes morphology and syntax, often complemented by phonetics, phonology, semantics, and pragmatics.
