Indubitably definition

We have many words in the English language to express a level of certainty. One way to understand what indubitably means is to imagine these words on a spectrum, ranging from least certain to most certain.

On the lower end of this spectrum, we have words like maybe and possibly.

In the middle, we have words like probably and presumably.

On the high end of the spectrum, we have words like certainly and definitely.

Indubitably is one of the very highest words on the scale—it expresses certainty without any doubt.

For example, if you say, “Einstein was probably clever,” you’re expressing some doubt in Einstein's intelligence.

On the other hand, if you say, “Einstein was indubitably clever”, that means you’re absolutely certain of his intellect.
