James: masc. proper name, name of two of Christ's disciples, late 12c. Middle English vernacular form of Late Latin Jacomus (source of Old French James, Spanish Jaime, Italian Giacomo), altered from Latin Jacobus (see Jacob).

race (n.2): "people of common descent," a word from the 16th century, from Middle French race, earlier razza "race, breed, lineage, family" (16c.), possibly from Italian razza, of unknown origin (cognate with Spanish and Portuguese raza). Etymologists say no connection with Latin radix "root," though they admit this might have influenced the "tribe, nation" sense.

Original senses in English included "wines with characteristic flavor" (1520), "group of people with common occupation" (c. 1500), and "generation" (1540s). Meaning "tribe, nation, or people regarded as of common stock" is by 1560s. Modern meaning of "one of the great divisions of mankind based on physical peculiarities" is from 1774 (though as OED points out, even among anthropologists there never has been an accepted classification of these).
