The correct answer is concept
The concept is that which is conceived in thinking about something or someone. It is the way of thinking about something, consisting of a type of appreciation through an opinion expressed, for example, when a good or bad concept of someone is formed. In this case, concept can be synonymous with reputation.
It can also be interpreted as a mental symbol, an abstract notion contained in each word of a language that corresponds to a set of characteristics common to a class of beings, objects or abstract entities, determining how things are.
The concept expresses the qualities of a thing or an object, determining what it is and its meaning.
The words in several languages have the same meaning because they express the same concept.
