The concept of lesson (from Latin reading) has several uses and meanings. One of the most common meanings refers to the instruction of theoretical and / or practical knowledge that a teacher makes to his disciples or students. For example: "The Greek history lesson seemed very entertaining", "The professor said that next week we will have a chemistry lesson in the laboratory", “Of the twenty boys, only three were satisfied with the lessons of the new teacher”.
A lesson is also what the teacher tells the student to study : "Perez, come forward to teach", “Tomorrow I have a geography lesson at school”, “I hope that the teacher does not call me to teach, because I did not study the topic of the day”.
Within the educational field, it should be stressed that it is essential that every lesson presented in class must have such important parts as an introduction, the content itself or the practical exercises.
It is also interesting to establish the existence of other kinds of lessons that are very important in what is the field of teaching. In this sense, we would have to highlight, for example, what is called the inaugural lesson, which is the conference that at the beginning of the course is one of the illustrious professors of the university in question.
In the same way, there is also what is known as a master lesson, which is the one carried out by a person specialized in a topic in a conference or seminar that precisely deals with it.
He example or the warning that, either by word or through an action, teach a mode of behavior It is also known as a lesson: "The victim's mother gave a lesson to those who ask for a hard hand in stating that she has forgiven the aggressor", “The disabled swimmer who crossed the English Channel offered a life lesson”, "If you keep bothering me, I'm going to teach you a lesson you'll never forget".
Also, we could not forget the fact that within our colloquial language we make use of a series of expressions that incorporate the term lesson that we are now analyzing. Thus, for example, we come across the verbal phrase "teach someone a lesson." With it, what we are trying to express is that someone has proceeded to show another that they have made a mistake and also proceed to correct it.
But there is more. There is also the phrase "take the lesson", which is used to express that a student is learning a subject thanks to a teacher who is giving all the necessary knowledge about it as well as the skills needed to work on it.
Lesson, on the other hand, is each chapter or section in which some writings are divided : “I have to read the fourth lesson of the document before the presentation”, “I have not understood the second lesson of the book clearly”.
The various ways to read ancient manuscripts , which may incorporate copyists' mistakes, are also known as lessons. The Bible , Greek poets and Latin prosistas have their lessons.
