* Metronome: This word refers to a device used to mark time in music, derived from the Greek words "metron" (measure) and "nomos" (law).
* Metropolis: This word describes a large and important city, from the Greek words "meter" (mother) and "polis" (city). This is a less direct connection to the root "metro."
While the root "metro" isn't used frequently, it's worth noting that the prefix "metro-" is more common, meaning "mother" or "womb." This prefix appears in words like:
* Metromania: An obsession with the mother.
* Metropathy: A disease affecting the mother.
* Metroscope: An instrument used to examine the uterus.
It's important to remember that these are examples, and the usage of "metro" as a root can be quite rare.
