 Their choices were adopted by the grammarian David van Hoogstraten in his "Aenmerkingen over de Geslachten der Zelfstandige Naemwoorden" ["Comments on the genders of the independent nouns"] (1700); where Vondel and Hooft disagreed, Van Hoogstraten would assign a gender to a noun by his own choice.These "gender lists" were steadily extended, especially by professor Adriaan Kluit (1735–1807), who revised Van Hoogstraten's work.Kluit's list formed the basis of later 19th-and early 20th-century practice.
