Unfair treatment of an individual based solely on their use of language. This use of language may include the individual's native language or other characteristics of the person's speech, such as an accent, the size of vocabulary (whether the person uses complex and varied words), modality, and syntax. It may also involve a person's ability or inability to use one language instead of another.
