historical usage of comprise

Comprise has had an interesting history of sense development. In addition to its original senses, dating from the 15th century, “to include” and “to consist of ” ( The United States of America comprises 50 states ), comprise has had since the late 18th century the meaning “to form or constitute” ( Fifty states comprise the United States of America ). Since the late 19th century it has also been used in passive constructions with a sense synonymous with that of one of its original meanings “to consist of, be composed of ”: The United States of America is comprised of 50 states. These later uses are often criticized, but they occur with increasing frequency even in formal speech and writing.
