Etymology: "Microcavities" is simply the plural of "microcavity," which is formed from two parts: "micro-," from Ancient Greek "mīkrós," meaning small, and "cavity," a word for a hollow space. Combining a Greek prefix with an English noun is a common way to build technical vocabulary, and this term follows that pattern directly. The "micro-" element came into English through modern scientific writing, where it was attached to many existing words to indicate something very small or a factor of one millionth. The "cavity" half is older and has a Latin root, but the combined word is a modern coinage made from these parts rather than an inherited term from antiquity.
