The word divulgar derives from the Latin "divulgāre" which means "to make available to the common people" or "to extend"; Lexically composed by the prefix "di" which means a "multiple separation", in addition to the voice "vulgus" which means "common people" or "vulgar", and the suffix "ar" which is a termination used for the verb formation. Divulgar is an intransitive verb that means: to make known or make public a particular secret, that is, to spread some type of knowledge, fact, news, language, etc. with the purpose that it becomes part of the public domain. It can also be defined as saying what had been confided as a secret, or had previously been unknown, and was manifested to certain people.
Disclosing often precedes the secret word, because it means to reveal something, and that something is often personal or private in nature. The job of a gossip columnist is to divulge which celebrities are secretly dating and which ones have been caught up in embarrassing situations. Although the word comes from the Latin word to make something public to the masses, it can also be used to describe information that is passed from one person to another. For example, a mother may disclose to her daughter that she was adopted.
In ancient times this word was also used to make known to the population information that was previously known only to a few people, or that was intended to be kept secret. On the other hand, it is important to publicize the meaning of the word disclose exposed by the RAE, which is "Publish, extend, make something available to the public."
