Etymology: "Nanism" is formed from "nano-", a combining form drawn from Greek "nanos", meaning "dwarf", and the suffix "-ism", which in medical usage denotes a condition or state. Put together, the word names the state of being abnormally small in stature, a dwarfism. The Greek root is the interesting part. "Nanos" is the source of the familiar modern prefix "nano-" meaning one billionth, which is a striking shift: the same root that once named a small human body now measures units too tiny to see. The prefix was adopted for that scientific sense, and the older medical use survives in words like this one.
