Did you hear about that new boat they just launched?

Yeah, they claim it’s nonsinkable!

Root Explanation

Nonsinkable → It is formed from "non-" (meaning not) and "sinkable" (from "sink" which comes from Old English "sincan", meaning to go down). The word "nonsinkable" means not capable of sinking or going down.

Memory Tip

Think of 'not' ('non-') being combined with 'going down' ('sink') — that's why nonsinkable means something that cannot sink.
