A pejorative or slur is a word or grammatical form expressing a negative or a disrespectful connotation, a low opinion, or a lack of respect toward someone or something. It is also used to express criticism, hostility, or disregard. Sometimes, a term is regarded as pejorative in some social or ethnic groups but not in others, or may be originally pejorative but later adopt a non-pejorative sense (or vice versa) in some or all contexts.
In historical linguistics, the process of an inoffensive word becoming pejorative is a form of semantic drift known as pejoration. An example of pejoration is the shift in meaning of the word silly from meaning that a person was happy and fortunate to meaning that they are foolish and unsophisticated. The process of pejoration can repeat itself around a single concept, leaping from word to word in a phenomenon known as the euphemism treadmill, for example as in the successive pejoration of the terms bog-house, privy-house, latrine, water closet, toilet, bathroom and restroom.
When a term begins as pejorative and eventually is adopted in a non-pejorative sense, this is called melioration or amelioration. One example is the shift in meaning of the word nice from meaning a person was foolish to meaning that a person is pleasant. When performed deliberately, it is described as reclamation or reappropriation. An example of a reclaimed word is queer, which was re-appropriated as a positive term by activists and academics starting in the early 1990s.
The Honest Jakes or Privy has graduated via Offices to the final horror of Toilet.
Linguistic reclamation, also known as linguistic resignification or reappropriation, refers to the appropriation of a pejorative epithet by its target(s).
