- holograph (n.)
[holograph 词源字典]
- "document written entirely by the person from whom it proceeds," 1620s, from Late Latin holographus, from Greek holographos "written entirely by the same hand," literally "written in full," from holos "whole" (see safe (adj.)) + graphos "written," from graphein "to write" (see -graphy). Modern use, with reference to holograms, is a 1960s back-formation from holography.[holograph etymology, holograph origin, 英语词源]
