Caucasian vs. White

Caucasian has two fairly distinct meanings, and the difference between them occasionally leads people to aver that one of them is incorrect. The earliest sense of the word is a literal one: “of or relating to the Caucasus (a region in southeastern Europe between the Black and Caspian seas) or its inhabitants.” The second refers to the racial group commonly referred to as white.

The objection to using Caucasian to refer to a white person is that many whites do not actually come from the Caucasus region. Be this as it may, there is no rule in language stipulating that the formation of a word must be based on logic; were this the case we would not call members of this racial group either Caucasian or white, since there are very few whose skin color is in fact that exact shade.
