Root Explanation

Semisubmersible → It is formed from "semi-" (meaning half) and "submersible" (from Latin "submergere", meaning to plunge or sink). The word describes something that is half submerged in water.

Memory Tip

Think of something that is 'half' ('semi-') 'sunk' ('submergere') in water — that's what semisubmersible means.
