As we enlarge our lexicons, we might spare a thought for Noël François de Wailly; he died on this date in 1801. A grammarian and lexicographer, he published Principes généraux de la langue française (1754) which revolutionized the teaching of grammar in France. The book was adopted as a textbook by the University of Paris and then more generally used throughout France in an adapted form in primary education.
