Esperantology
Esperantology (eo: Esperantologio) or Esperantic studies, is a scientific discipline of philology dealing with every aspect of the Esperanto language, including linguistics and literary criticism of the language and its literature, but also, for example, philosophy, didactic methods, psycholinguistics, sociolinguistics and its history, the languages derived from it and the reform projects. Esperantology is often understood to be a sub-area of interlinguistics though it turns the attention to its artificial origins instead of its subsequent natural and culture-creating evolution.
