A grammar school is one of several different types of school in the history of education in the United Kingdom and other English-speaking countries, originally a school teaching Latin, but more recently an academically oriented selective secondary school.
The original purpose of medieval grammar schools was the teaching of Latin. Over time the curriculum was broadened, first to include Ancient Greek, and later English and other European languages, natural sciences, mathematics, history, geography, art and other subjects. In the late Victorian era, grammar schools were reorganised to provide secondary education throughout England and Wales; Scotland had developed a different system. Grammar schools of these types were also established in British territories overseas, where they have evolved in different ways.
