In linguistics, approbatives are words or grammatical forms that denote a positive affect; that is, they express the appreciation or approval of the speaker. Sometimes a term may begin as a pejorative word and eventually be adopted in an approbative sense. In historical linguistics, this phenomenon is known as amelioration. Examples from English include "punk", "nerd", "badass", "sick", and "killer".
