Linguistic discrimination

Linguistic discrimination (also called glottophobia, linguicism and languagism) is the unfair treatment of people based upon their use of language and the characteristics of their speech, such as their first language, their accent, the perceived size of their vocabulary (whether or not the speaker uses complex and varied words), their modality, and their syntax. For example, an Occitan speaker in France will probably be treated differently from a French speaker.
