Did you know they can transilluminate your hand to check for issues?

Really? I had no idea that was a thing!

Root Explanation

Transilluminate → It is formed from "trans-" (meaning across) and "illuminare" (meaning to light up or make clear). The word describes the act of lighting up or making something clear by passing light through it.

Memory Tip

Picture light passing 'across' ('trans-') to 'illuminate' something — that's how transilluminate means to light up by passing light through.
