central

英 ['sentr(ə)l] 美 ['sɛntrəl]

central (adj.): 1640s, from French central or directly from Latin centralis "pertaining to a center," from centrum (see center (n.)). Centrally is attested perhaps as early as early 15c., which might imply a usage of central earlier than the attested date.

Slightly older is centric (1580s). As a U.S. colloquial noun for "central telephone exchange," first recorded 1889 (hence, "Hello, Central?"). Central processing unit attested from 1961. Central America is attested from 1826.
