A pejorative (also called a derogatory term, derogative term, a term of abuse, or a term of disparagement) is a word or grammatical form expressing a low opinion of someone or something, or showing a lack of respect for someone or something. It is also used as a criticism, hostility, disregard and/or disrespect. A term can be regarded as pejorative in some social or cultural groups but not in others. Sometimes, a term may begin as a pejorative and eventually be adopted in a non-pejorative sense (or vice versa) in some or all contexts.
