What is the opposite of conspicuous?

The term "conspicuous" refers to something that is easily seen or noticed; it generally implies a certain level of prominence or visibility. Therefore, the opposite would be a word that conveys the idea of being hidden or difficult to see.

The option "obscure" fits this definition perfectly, as it means not easily seen or not well-known, emphasizing the lack of visibility or prominence. In contrast, the other options—such as "visible," "prominent," and "noticeable"—carry connotations of visibility and prominence, which are directly opposed to the meaning of "obscure." Thus, "obscure" accurately represents the antonym of "conspicuous."
