Etymology
The word "polarizer" is a modern scientific and sociological term built from classical components. Its core, "polar," originates from the Latin polus, meaning the end point of an axis, which itself was borrowed from Greek polos (pivot, axis, sky). The suffix "-ize," of Greek origin, was added to form the verb "polarize," meaning "to cause to concentrate about two opposite extremes." Finally, the agent suffix "-er" was appended to create a noun for the entity that performs this action. Thus, the literal construction "thing that makes (something) polar" logically evolved to describe both a physical device that aligns light waves to a single plane and a metaphorical force that drives opinions to opposing extremes.
Analysis
Structure: polar (relating to a pole) + ize (to make, to cause) + er (agent or instrument)
- polar: From Latin polaris (of or relating to a pole), from polus (end of an axis, pole). In this word, it denotes the concept of having poles or opposite extremes.
- ize: A verb-forming suffix from Greek -izein, via Latin -izare, meaning "to render, to make, to become."
- er: An agent noun suffix from Old English -ere, via Proto-Germanic, indicating a person or thing that performs an action.
