As I was helping my 8th grader study her science terms, one word grabbed my attention . <Sublimation> is a process resulting in a substance gaining energy. This caused me to wonder about <sub>, which I knew was a prefix meaning under, below or beneath. My curiosity prompted me to start an investigation to find out how <sub> contributes to the meaning of this word. Attached is a matrix and the information I uncovered from various sources. Please feel free to offer feedback. I am by no means comfortable with this word investigation process.
