Etymology

The verb "refract" is a direct borrowing from Latin refractus, the past participle of refringere, meaning "to break up" or "to break open." This Latin verb is itself a compound of the prefix re- ("back") and frangere ("to break"). The core logic of the word lies in this literal image of breaking a ray of light, bending it back from its original straight path. Over time, this specific physical concept of light bending as it passes between substances became the sole, precise scientific meaning of the English term, moving from the general idea of "breaking back" to the specific phenomenon of directional change in waves.

Analysis

Structure: re (again, back) + fract (break) re: Latin origin, a prefix meaning "again" or "back." fract: Latin origin, from the root frangere meaning "to break."
