Etymology

The prefix micro originates from the Greek word mikros, meaning "small." It entered English via scientific Latin in the 17th century, primarily used to denote minute measurements (e.g., micrometer). Over time, it expanded into general vocabulary (e.g., microscope for viewing tiny objects) and technology (e.g., microchip). Its adoption reflects scientific progress in quantifying and manipulating small-scale phenomena.
