late 14c., "piece of land enclosed for breeding beasts and fowls," from Anglo-French and Old North French warenne, Old French garenna "game park," possibly from Gaulish *varenna "enclosed area," related to *varros "post." Or the Old French forms may derive from the present participle of Old French warir "defend, keep," from the Germanic root *war- "to protect, guard" (source of Old English warian "take care;" see warrant (n.)). Later especially "piece of land for breeding of rabbits" (c.1400), which led to the transferred sense of "cluster of densely populated living spaces" (1640s).
Warren War·ren (wôr'ən), John Collins. 1778-1856.
American surgeon who gave the first public demonstration (1846) of the use of ether as an anesthetic for a surgical procedure.
A political leader and judge of the twentieth century. Warren was governor of California before being named chief justice of the Supreme Court in 1953, and he served on the Court until 1969. His time as chief justice was marked by boldness in interpreting the Constitution; the “Warren Court” often brought the Constitution to the support of the disadvantaged. (See Brown versus Board of Education and Miranda decision). Warren also led a government commission investigating the assassination of President John F. Kennedy (see Lee Harvey Oswald).
