sentences: "Eschew obfuscation", also stated as "eschew obfuscation, espouse elucidation", is a humorous fumblerule used by English teachers and professors when lecturing about proper writing techniques.Literally, the phrase means "avoid being unclear" or "avoid being unclear, support being clear", but the use of relatively uncommon words causes confusion in much of the audience (those lacking the vocabulary), making the statement an example of irony, and more precisely a heterological phrase.
