Etymology: The word is a plain compound: "micro-", from Ancient Greek "mīkrós" meaning "small", joined to "machine", which came into English from Middle French "machine" after passing through Latin "māchina" and ultimately Greek "mēkhanē", a device or contrivance. Put together, a micromachine is literally a very small machine. The "micro-" element has a longer and more varied career than the word it sits on. In Greek it was a plain adjective for small size, and it became a productive combining form in English, where it now attaches to all sorts of nouns to mean something a millionth of the scale of the original. The "machine" half travelled a different route, from a Greek word for a clever device or stratagem into Latin and then French before English adopted it. Because the compound follows the same pattern as older pairings such as "microscope" and "micrometer", its meaning is transparent. The word describes a device at the scale of micrometres or smaller rather than a specific technology, and it is used in fields such as medicine and engineering wherever miniature devices are built for precise work.
