Why is the term Hottentot no longer used for Khoekhoe languages?

The term "Hottentot" is no longer used for Khoekhoe languages because it is considered to be pejorative.12

Historically, the term was fashioned by Dutch and later Afrikaner settlers, likely as an imitation of the click sounds characteristic of the language. In contrast, the people refer to themselves as Khoekhoe, which translates to "men of men". Due to its origins as an external label and its derogatory connotations, the term is now widely recognized as offensive and has been abandoned in favor of the group's own self-designation.231
