Which word best describes something that is not currently evident but could exist?

The word "latent" refers to something that is present but not visible or active at the moment; it can exist in a hidden state. It is often used to describe potential that has not yet manifested or become apparent. In contexts such as medicine, psychology, or talent, it indicates that there is an underlying quality or capability that has not yet been fully realized or expressed.

In contrast, "impetuous" refers to someone acting quickly without thought or care, which does not relate to the idea of something being hidden or inactive. "Indolent" describes someone who is lazy or inactive, which again does not convey the potential for existence. "Judicious" implies having, showing, or done with good judgment or sense, which is unrelated to the concept of latent presence or potential. Thus, "latent" is the most fitting choice as it encapsulates the idea of something that is not currently evident but has the capacity to exist.
