From Latin conceptus, the term concept refers to the idea that forms the understanding . It's about a thought which is expressed by words: "I am not clear about the concept of civil responsibility", “My concept of friendship is very different from yours”.
A concept is, therefore, a cognitive unit of meaning . It is born as an abstract idea (it is a mental construction) that allows us to understand the experiences arising from the interaction with the environment and that, finally, is verbalized (put into words).
It is important to keep in mind that the notion of concept always appears linked to the context . The conceptualization it develops with the interaction between the senses, the language and cultural factors. Knowing something through experience and transforming that knowledge into a concept is possible by the references that are made about a thing or situation that is unique and unrepeatable.
The individual, however, is marked with a own name , not with a concept. He rock It is a concept (an idea that involves notions of style, rhythm, lyric, etc.), instead the Beatles or The Rolling Stones They are rock bands (which helped to build the concept).
All of the above leads to the fact that on many occasions we find the fact that many people tend to confuse two terms: concept and definition. However, they are not synonyms.
The key to understanding the differences between the two is that the aforementioned definition is the description that is made universally and precisely of an idea, an expression or a branch of knowledge. Meanwhile, the concept can determine what is the opinion that a person has about a specific aspect. That is, the concept is much less precise and more particular.
In this way, as examples we can use the following. In the case of the definition, the following phrase would serve: "Medicine is the scientific branch that is responsible for studying both life and death and diseases of human beings." For its part, the concept example would be: "There are many concepts about the application of Medicine in the field of personality problems."
It is important to underline in addition to all the above that in the past the term concept was used as a synonym for a term that now has nothing to do with it. Specifically, a time before concept was also used to refer to a fetus.
Concept is, on the other hand, the credit that you have someone or something. In this sense, the word is associated with a judgment or one opinion (This is a clearly subjective concept): “The teacher doesn't have a good concept about me”, "I think Roberto will have to do a lot to improve the concept of the boss".
Also, we must not overlook that there is an expression that makes use of the term that now concerns us. We are referring to the adverbial phrase "form concept" which is the one used to establish that a particular person is carrying out an opinion or an idea on an issue in his mind after having considered all the circumstances that surround.
