indubitable

What does "indubitable" mean?
The word "indubitable" describes something so certain, clear, or self-evident that it is impossible to doubt. Imagine a fact that stands like a mountain in the fog; while everything else is obscured by uncertainty, this truth remains solid, undeniable, and perfectly visible. It is a formal, sophisticated term often used in academic, legal, or philosophical contexts to emphasize that a conclusion is beyond debate. You would rarely use this in casual conversation; it is best reserved for moments when you want to underscore that an argument is airtight or a truth is absolute.
