Etymology
The etymology of infrastructure dates back to ancient Rome.
The word “infrastructure” is said to be a combination of two words in Latin, a language used
by ancient Romans : “inferus” meaning "below", and “structura”
, meaning “building”.
The ancient Romans are called the "Fathers of Infrastructure" by modern people.
In Japan, it is often abbreviated as "infra", which is derived from "inferus".
Originally, "infra" has the same meaning as "inferus" and expresses "below".
The antonym of "infra" is "super," which means "excellent" or "first-class".
In Japanese, there are phrases such as “social infrastructure”, “infrastructure institution”, and “economic infrastructure”.
Also, in Japan, infrastructure is not used to mean substructure.
