Etymology
The word 'interstate' is a modern American English compound formed from the Latin prefix 'inter-' and the noun 'state'. The prefix 'inter-', derived from the Latin preposition meaning "between" or "among," has been a productive element in English for centuries, used to indicate mutual or spatial relationships. The noun 'state', tracing back to Latin 'status' (meaning "condition" or "standing"), evolved through Old French to signify a sovereign political entity. When combined in the late 19th century, the term 'interstate' logically described anything existing or occurring between such sovereign entities, a concept later concretized in the 20th century with the naming of the US Interstate Highway System designed to connect the states.
