It is called ideogram to the symbol or conventional image that is used representing an idea , not including words that mean it. Its economy, the speed with which it is perceived and the universality are the main characteristics of these elements.
He peace symbol consisting of a circle with three lines inside it is a example of ideogram Nowhere in its structure does the term include "peace" but, by convention and tradition, currently anyone who sees it can understand what it represents.
He yin and yang chart , where black and white are combined, is another ideogram. In this case, the symbol allows the representation of the duality that the taoism He attributes it to what exists in the universe. Usually yin and yang are summarized in the expression “In everything bad there is something good and in everything good there is something bad”.
Many times the confusion arises between this concept and that of pictogram . While the ideogram is the representation of an idea, the pictogram appeals to a drawing to figuratively represent an image. A woman drawn on the door of a bathroom is a pictogram indicating that the bathroom is for female use.
It should be noted that the notion of pictogram is also used to refer to the symbol used in certain tongues what means a phrase, a word or a morpheme, but that does not represent a phoneme or a syllable . In Chinese and Japanese, to mention two languages, ideograms of this type are used.
The communication Based on this kind of symbols has its advantages and disadvantages. As mentioned in a previous paragraph, economics when drawing them is one of its clear advantages: in most cases, it is much easier and faster to draw an ideogram than to write the sentence to which it refers. If we return to the drawing of a woman at the door of a public restroom, it goes without saying that this graphic is considerably simpler and requires fewer strokes than the phrase "Restroom for the exclusive use of women."
Another advantage of ideograms is that they can be learned and understood by people of all ages and, much more importantly, from all over the world regardless of language Let them speak. Linguistic differences are one of the least possible barriers to penetrate for our species, and this can make a foreign experience especially difficult for someone who wishes to forge a better future based on work and effort. There are many cases of immigrants who do not know a word of the local language, but at least they may understand certain posters thanks to the use of ideograms.
In the case of children, as they usually learn to read and write at age five, their first relationship with the written language usually occurs through logos and ideograms . It is common for very young children to recognize logos of your favorite brands before you can read, even if they are made up of words.
On the other hand are the disadvantages of ideograms. Although it seems contradictory to what was stated above, given the lack of knowledge of a given ideogram it may be easier to understand the sentence to which it refers. Let's not forget that not all are for international use and that some may be very typical of a particular region: if we arrive in a foreign country whose language we speak quite fluently but we do not know an ideogram that has become fashion Recently, we probably don't understand it even if we know how to say the phrase it represents.
