Topic: Antonyms, Subject: English Grammar (ইংরেজি গ্রামার)

Best Answer Explained in Below-:

To understand why "suppress" is the antonym of "promulgate," we first need to define both terms. "Promulgate" means to make something widely known, often in the context of laws, regulations, or ideas. It involves spreading information, ensuring that it reaches a broad audience. For example, a government may promulgate a new law by publicizing it through various media outlets.

In contrast, "suppress" means to restrain, inhibit, or prevent something from being expressed or disseminated. When one suppresses information, they actively work to keep it hidden or limit its spread. For instance, a government might suppress dissenting opinions or information that contradicts its narrative.

Given these definitions, the two terms represent opposing actions: "promulgate" is about spreading and promoting information, while "suppress" is about preventing that information from reaching people. The other options—advertise, dignify, and propagate—do not convey a sense of restriction or hindrance; they are more aligned with dissemination or enhancement, rather than obstruction. Therefore, the correct antonym for "promulgate" is indeed "suppress."
