1 The present participle was variable in gender and number until the 17th century (Anne Sancier-Château [1995], Une esthétique nouvelle: Honoré d'Urfé, correcteur de l'Astrée, p. 179). The French Academy would eventually declare it not to be declined in 1679.
2 The gerund was held to be invariable by grammarians of the early 17th century, and was usable with preposition en, as in Modern French, although the preposition was not mandatory (Anne Sancier-Château [1995], op. cit., p. 180).
