There are organizations or entities whose name is popularly known by their initials, that is, the first letters that form the name of certain organizations. Thus, instead of saying the United Nations, it can be directly said the UN. Acronyms
The function of acronyms is double: on the one hand, they serve to simplify the language ; on the other hand, to achieve greater communicative effectiveness. It is easier to say PSDB than to use the full term, Brazilian Social Democratic Party. Thus, it can be said that the acronyms serve as a principle of economy in language.
From a marketing point of view, the use of acronyms makes it possible to better identify an identity. Marketing professionals are well aware of the usefulness of acronyms, because through them a better effectiveness in communication is achieved .
Acronyms should not be confused with abbreviations, as the abbreviation is the reduction of a word, for example, etc. it means etcetera; A/C to care and BC equals BC.
The acronym concept cannot be confused with an acronym, because the acronym exists when the acronyms form a word (the term laser is formed by the expression Light Amplification by Stimulated Emission of Radiation; or ICT which means Information and Communications Technology). In this way, every acronym is an acronym, but not every acronym is an acronym.
The use of acronyms in everyday language poses some dangers
The most common is to assume that an acronym is known. Let’s give an example: the AVE (model train) is a well-known acronym in Spain, but not outside the country; Argentines know the meaning of DGI, but the rest of the world doesn’t. Another common mistake is the abuse of acronyms. Thus, if a journalist writes “At the UN, the members of the IMF met to discuss the US GDP and address the problems of NATO” we would be faced with technically correct information, but with too many acronyms (five in the same sentence).
Some linguists warn of language impoverishment as a result of abuse of acronyms. It is not a question of not using them when it is convenient, but of using them to a certain extent.
A fair rule for the correct use of acronyms would be to take into account the context of the communication. In this way, when we know that the interlocutor knows the meaning of certain acronyms, its use makes sense. For example, a doctor can address the other using acronyms of the specialty they share, but in the communication between doctor and patient, the language is different.
