Word Origin and History for sanguinary

"characterized by slaughter," 1620s, possibly from French sanguinaire, or directly from Latin sanguinarius "pertaining to blood," from sanguis (genitive sanguinis) "blood," of unknown origin. Latin distinguished sanguis, the generic word, from cruor "blood from a wound." The latter word is related to Greek kreas "meat," Sanskrit kravis- "raw flesh," Old English hreaw- "raw" (see raw).
