Basic linguistic notions

Lexical cohesion occurs when two words in the text are semantically related in the same way – in other words, they are related in terms of their meaning. Two major categories of lexical cohesion are reiteration and collocation. Reiteration includes repetition, synonym or near synonym use and the use of general words. E.g. (1) You could try driving the car up the slope. The incline isn’t at all that steep. (2) Pneumonia arrives with the cold and wet conditions. The illness can strike everyone from infants to the elderly.
Collocation includes all those items in text that are semantically related. The items may be related in one text and not related in other. For instance, the words ‘neighbour’ and ‘scoundrel’ are not related at all. However, in the following text they are collocated: My neighbour has just let one of his trees fall into my garden. And the scoundrel refuses to pay for the damage he has caused.
Cohesive ties within the text are also formed by endophoric relations. Endophoric relations are of two kinds – those that look back in the text for their interpretation are called anaphoric relations; those that look forward in the text are called cataphoric relations:
Look at the sun. It is going down quickly. ‘It’ refers back to ‘the sun’.
It is going down quickly, the sun. ‘It’ refers forwards to ‘the sun’.
4. Textual deictic markers.
As a linguistic term deixis means ‘identification by pointing’.
Much of the textual meaning can be understood by looking at linguistic markers that have a pointing function in a given context. For example, consider the following note pinned on a professor’s door: “Sorry, I missed you. I’m in my other office. Back in an hour.” Without knowing who the addressee is, what time the note was written, or the location of the other office, it is really hard to make a precise information of the message. Those terms that we cannot interpret without an immediate context are called deixis. Deictic terms are used to refer to ourselves, to others, and to objects in our environment. They are also used to locate actions in a time frame relative to the present. Deictic terms can show social relationship – the social location of individuals in relation to others. They may be used to locate parts of a text in relation to other parts.
Deictic expressions are typically pronouns, certain time and place adverbs (here, now, etc.), some verbs of motion (come/go), and even tenses. In fact all languages have expressions that link a sentence to a time and space context and that help to determine reference.
We can identify five major types of deictic markers – person, place, time, textual and social.
Person deixis refers to grammatical markers of communicant roles in a speech event. The first person is the speaker’s reference to self; the second person is the speaker’s reference to addressee(s) and the third person is reference to others who are neither speaker nor addressee.
Place deixis refers to how languages show the relationship between space and the location of the participants in the text: this, that, here, there, in front of, at our place, etc.
