From Latin vocabŭlum, he vocabulary It is formed by the set of words of a language . Such vocabulary is known by people who share a common language and can also be compiled in a dictionary .
At a more specific level, the vocabulary is the set of words that dominates a person or that you use in your everyday conversations. This means that if a language has a vocabulary of 100,000 words, a person may handle 60,000 words. Therefore, the vocabulary of said subject will be more limited than the general vocabulary of the language.
In this sense, it is necessary to determine that any person who is encouraged to learn another language different from his mother tongue is in need of devoting many hours of study to learn vocabulary. And it is a fundamental key to be able to handle in that other language.
In addition, it should be stressed that there are, therefore, two clearly differentiated types of vocabulary. One of them is what is known as active vocabulary, and it is that one that a person not only understands on his own but also uses frequently when expressing himself.
The second one is the one that receives the name of passive vocabulary. This, on the other hand, is one that someone can understand without any problems and without help but then is not able to use when expressed, either in writing or orally.
It is common for a person's vocabulary to be associated with their education or cultural level. It is generally considered that, the greater the variety of words, the greater the intellectual capacity. The richness of vocabulary is a useful instrument for social adaptation and for communicating successfully with a wider range of people. Remember that the vocabulary used to speak with a friend differs from that used to communicate with a hierarchical superior or a stranger.
For example: "The speaker showed his excellent vocabulary in a dissertation that amazed those present", “I need an English dictionary: there are words from the book that are not yet part of my vocabulary”, “Take care of your vocabulary, you shouldn't talk that way at school”.
In addition to all of the above, we cannot forget that the term vocabulary is used to refer to both the book that includes the words that shape a language and the catalog where they appear collected and next to them the meaning of each a.
It is known as jargon to a variant of the standard language that uses a special vocabulary in order to distinguish social groups or to hide the true meaning of the concepts: “Bondi armed with the cap” It is an expression that is used in Argentine prison jargon to refer to a problem ("Bondi was armed") with a policeman ("the cap").
Specifically, we have to clarify that jargon can and can be classified into two large groups: those of a professional type, which, as the name implies, are specifically used in a specific area such as the sanitary one; and the social ones, which are used in certain groups as a way of understanding each other exclusively.
