Meanings

Adjective

  1. not yet shown by evidence or experience to be true, valid, or reliable

Beyond the definition

Something "unproven" hasn't been shown to be true or effective yet. It doesn't necessarily mean it is false, just that there isn't enough evidence to support it. Think of a detective investigating a case—until they find solid clues, the suspect's guilt remains unproven. Or imagine a new medicine; it's "unproven" until rigorous clinical trials demonstrate its benefits.

You might hear "unproven technology" referring to inventions still in development, or an "unproven theory" that scientists are still investigating. It's a word often used when discussing possibilities, potential, and caution, because something unproven could turn out to be wrong. A chef trying a new recipe for the first time is working with unproven methods.
