چکیده (انگلیسی):

This paper outline a brief philosophical way of thenature of human language, from Plato (427-347 BC) to
Port-Royal grammar. Plato (427-347 BC) and Aristotle (384-322 BC) present the question of the correctness
of the names. In the middle Ages, the nature of language spread over by several schools of thought very
heterogeneous and appear the first grammars. In the 12th century, the speculative grammar presents a
strictly scientific basis for language: deductive and universal. In the early modern, specifically with the
Renaissance, modern thought arises and there is theresumption of the classical tradition and the expansion
of the literature, arts, culture and a new philosophical and ethical conception. In the 17th century, the
language studies focused on the modern languages ofEurope. The publication of the Port-Royal grammar
becomes the greatest exponent of Cartesian rationalism, reflecting the prescriptivism of traditional grammar.
