What is the Meaning & Definition of main Idea

When we speak of language in any of its manifestations, we find that it will always involve the need to communicate a message from a sender to a receiver. That message can be structured many different ways and forms even if one of the elements that always prevails is the notion of main idea. The main idea of a message can be understood as the center of what you want to communicate, the most important thing and that is intended to pass from one person to another. The main idea of a message is one that sets the message you want to communicate something and do it in any of the varied forms that exist. The main ideas can be more or less clear messages and this will also depend on the type of communication that is used: while spoken language can be much simpler than the writing and you can find the main ideas much easier, in written language the main ideas can be clearly arranged but can also be underlying what is written so that the reader must reflect in order to find what the author really wanted mean.
The communication of the main idea may also depend on different situations or circumstances, as well as the characters that made the communication, of the system of language that feature and many other aspects. In this sense, the main ideas of a message can not be clearly expressed if the person communicating does not clear the what or the how of his message. This happens both in the language of written type as in the oral type interchangeably.
It is important to understand that the main idea of a message is always the most important to communicate, and despite being the same embellished by other elements of the language, it is one that should prevail understanding proper message will be fulfilled.
