Root Explanation
Submersible → It is formed from "sub-" (meaning under) and "mergere" (meaning to plunge or immerse). The word describes something that can be plunged or immersed under water.
Memory Tip
Think of something that goes 'under' ('sub-') the water by 'plunging' ('mergere') — that's what submersible means.
