Sensitive Note

During the slavery and Jim Crow eras, white southerners would use the term boy to refer to or address a Black adult male, implying that Black people were inferior. In the meaning “native male servant,” boy was originally used in colonial territories and in the ports of China, Japan, etc., through which trade with foreign countries was permitted by special treaty.

Usage

Where does the word boy come from? Like girl, boy dates back to around 1250–1300. Also like the word girl, the ultimate origin of the word boy is obscure.There are some clues to the roots of boy, however. It might be based on the Old English Bōia, a male given name. Furthermore, boy is related to the Frisian boi, "young man," and the German Bube, "knave, boy, lad." (Frisian, a language spoken in the northern Netherlands, is the Germanic language most closely related to English.) Interestingly, that German sense of "knave" is close in meaning to “male servant,” one of the earliest uses of boy. Boy isn't alone: it finds lots of company in other English words that seem simple but whose origins are not.
