Root Explanation

Indubitably is formed from "in-" (meaning not) and "dubitabilis" (from Latin, meaning able to be doubted). The word means not able to be doubted, or certainly true.

Memory Tip

Think of 'not' ('in-') being able to 'doubt' ('dubitabilis') something — that's why indubitably means something is certainly true.
