Black's Law Dictionary
Henry Campbell Black, M.A. · 1910
In England, this term designates a school in which such instruction is given as will prepare the student to enter a college or university, and in this sense the phrase was used in the Massachusetts colonial act of 1647, requiring every town containing a hundred householders to set up a "grammar school." See Jenkins v. Andover, 103 Mass. 97. But in modern American usage the term denotes a school, intermediate between the primary school and the high school, in which English grammar and other studies of that grade are taught.
