grammar Look up grammar at Dictionary.com
late 12c., gramarye, from O.Fr. grammaire "learning," especially Latin and philology, from L. grammatica, from Gk. grammatike tekhne "art of letters," with a sense of both philology and literature in the broadest sense, from gramma "letter," from stem of graphein "to draw or write." Restriction to "rules of language" is a post-classical development, but as this type of study was until 16c. limited to Latin, M.E. gramarye also came to mean "learning in general, knowledge peculiar to the learned classes" (early 14c.), which included astrology and magic; hence the secondary meaning of "occult knowledge" (late 15c.), which evolved in Scottish into glamour (q.v.). A grammar school (late 14c.) was originally "a school in which the learned languages are grammatically taught" [Johnson, who also has grammaticaster "a mean verbal pedant"]. In U.S. (1860) the term was put to use in the graded system for "a school between primary and secondary, where English grammar is taught."
