Root Explanation

Indubitable → It is formed from "in-" (meaning not) and "dubitabilis" (from Latin, meaning able to be doubted). The word "indubitable" means not able to be doubted or unquestionable.

Memory Tip

Think of 'not' ('in-') being combined with 'able to be doubted' ('dubitabilis') — that's why indubitable means something that cannot be doubted.
