Etymology: "Microholes" is simply the plural of "microhole," a compound formed from the prefix "micro-" and the noun "hole." The prefix comes from the Greek "mikros," meaning "small," and it has been used in English as a combining form to mark something extremely small, as in "microscope" or "microchip." Attaching it to "hole" produces a term for openings far too small to be seen without magnification. The base word "hole" is ancient and plain, descending from Old English "hol," meaning a hollow or cavity. Combined with the prefix, the compound describes a gap whose defining feature is its scale rather than any special shape or purpose. Because "micro-" is so productive in modern technical vocabulary, "microhole" can be understood at a glance by anyone who knows the prefix.

Synonyms: micropores, tiny holes, minuscule openings, small perforations
