Le Bon Usage

Le Bon Usage (French pronunciation: [lə bɔn‿yzaʒ], Good Usage), informally called Le Grevisse, is a descriptive book about French grammar first published in 1936 by Maurice Grevisse, and periodically revised since.

It describes the usage of the French language, primarily in its written literary form.

In 1936, the first edition was published by De Boeck Supérieur (then named Duculot).

The high praise of André Gide in the literary supplement of Le Figaro in February 1947 contributed to its success.

[1] After the death of Grevisse in 1980, his son-in-law André Goosse, also a grammarian, took over and published the 12th and 13th (1993) editions.
