The expository text is the speech that manages to transmit information, with a massive or specialized target audience, through an objective reading of the data and with the necessary explanations where appropriate.
They are expository texts (or explanatory texts as they are also called) manuals, encyclopedias, scientific magazines, informative articles, rules of the game, etc.
In these texts, we will recognize certain elements that will almost always be present: there is a central concept and complementary information, generating an ordered structure (presentation, development and conclusion); there is a purpose, generally to make something known and to instruct; the issuer can be individual or collective; the receiver must be able to understand the text either because it points to a certain sector or because he has the required clarifications; the objective character must prevail; there should be no ambiguity, clarity of concepts being essential; usually, the chosen tense is the present.
As stated above, expository text must be understandable. For this, there are many linguistic resources that the sender must use conscientiously:
– The description in detail is a mainstay of expository text. This type of discourse is based on detailing the notions we want to convey.
– The definitions, being merely informative and objective, meet all therequirements of this type of text, so they are widely used in this speech.
– Through comparisons with other concepts, with which the receiver may be more familiar, it is possible to improve the interpretation and understanding of the text.
– The examples, although sometimes ignored by some when doing a reading, are very helpful in explaining concepts. With examples we materialize and specify what we are trying to explain.
