The term Cartesian linguistics was coined with the publication of Cartesian Linguistics: A Chapter in the History of Rationalist Thought (1966), a book on linguistics by Noam Chomsky. The word "Cartesian" is the adjective pertaining to René Descartes, a prominent 17th-century philosopher. However, rather than confine himself to the works of Descartes, Chomsky surveys other authors interested in rationalist thought. In particular, Chomsky discusses the Port-Royal Grammar (1660), a book which foreshadows some of his own ideas concerning universal grammar.

Avram Noam Chomsky is an American linguist, philosopher, cognitive scientist, historian, social critic, and political activist. Sometimes called "the father of modern linguistics", Chomsky is also a major figure in analytic philosophy and one of the founders of the field of cognitive science. He is Laureate Professor of Linguistics at the University of Arizona and Institute Professor Emeritus at the Massachusetts Institute of Technology (MIT), and is the author of more than 150 books on topics such as linguistics, war, politics, and mass media. Ideologically, he aligns with anarcho-syndicalism and libertarian socialism.

De vulgari eloquentia "on vernacular eloquence" is the title of a Latin essay by Dante Alighieri. Although meant to consist of four books, it abruptly terminates in the middle of the second one. It was probably composed shortly after Dante went into exile, circa 1302-1305.

Hartwig Derenbourg was a French Orientalist.

Dictionarium quatuor linguarum is a 16th-century book by the German polymath Hieronymus Megiser that includes a multilingual dictionary and a multilingual grammar of Italian, Slovene, German, and Latin. It also includes some Croatian words. It was compiled and published in 1592 in Graz (Austria), then part of the Habsburg Monarchy. The dictionary is the first multilingual dictionary of Slovene. The appendix, named Exempla aliquot declinationum et coniugationium contains some grammar of the included languages and has been recognised as the second grammar of Slovene and the first multilingual grammar that includes Slovene. The book marks the beginning of Slovene lexicography. An extended edition was published under the same title in 1744 at Klagenfurt (Austria) by the Jesuits. This second edition also contains example phrases in German and Slovene, illustrating the use of the entries given. The number of Slovene equivalents in this edition is notably higher; they often reflect Carinthian Slovene.

The Erotemata (Ἐρωτήματα) are the first printed basic Greek grammar in use in Western Europe, written by Manuel Chrysoloras who was a pioneer is spreading Greek literature in Western Europe.

The International Phonetic Alphabet was created soon after the International Phonetic Association was established in the late 19th century. It was intended as an international system of phonetic transcription for oral languages, originally for pedagogical purposes. The Association was established in Paris in 1886 by French and British language teachers led by Paul Passy. The prototype of the alphabet appeared in Phonetic Teachers' Association (1888b). The Association based their alphabet upon the Romic alphabet of Henry Sweet, which in turn was based on the Phonotypic Alphabet of Isaac Pitman and the Palæotype of Alexander John Ellis.

Kavirajamarga is the earliest available work on rhetoric, poetics and grammar in the Kannada language. It was inspired by or written in part by the famous Rashtrakuta King Amoghavarsha I, and some historians claim it is based partly on the Sanskrit text Kavyadarsha. Some historians believe Kavirajamarga may have been co-authored by a poet in the king's court, the Kannada language theorist Sri Vijaya.

Gottfried Wilhelm (von) Leibniz was a prominent German polymath and one of the most important logicians, mathematicians and natural philosophers of the Enlightenment. As a representative of the seventeenth-century tradition of rationalism, Leibniz developed, as his most prominent accomplishment, the ideas of differential and integral calculus, independently of Isaac Newton's contemporaneous developments. Mathematical works have consistently favored Leibniz's notation as the conventional expression of calculus. It was only in the 20th century that Leibniz's law of continuity and transcendental law of homogeneity found mathematical implementation. He became one of the most prolific inventors in the field of mechanical calculators. While working on adding automatic multiplication and division to Pascal's calculator, he was the first to describe a pinwheel calculator in 1685 and invented the Leibniz wheel, used in the arithmometer, the first mass-produced mechanical calculator. He also refined the binary number system, which is the foundation of nearly all digital computers, including the Von Neumann machine, which is the standard design paradigm, or "computer architecture", followed from the second half of the 20th century, and into the 21st.

Lingua Aegyptiaca Restituta was a 1643 work about the Coptic language by the Jesuit scholar Athanasius Kircher.

Obeliscus Pamphilius is a 1650 work by the Jesuit scholar Athanasius Kircher. It was published in Rome by Ludovico Grignani and dedicated to Pope Innocent X in his jubilee year. The subject of the work was Kircher's attempt to translate the hieroglyphs on the sides of an obelisk erected in the Piazza Navona.

Charles Kay Ogden was an English linguist, philosopher, and writer. Described as a polymath but also an eccentric and outsider, he took part in many ventures related to literature, politics, the arts and philosophy, having a broad effect particularly as an editor, translator, and activist on behalf of a reformed version of the English language. He is typically defined as a linguistic psychologist, and is now mostly remembered as the inventor and propagator of Basic English.

Pratishakhya, also known as Parsada, are Vedic-era manuals devoted to the precise and consistent pronunciation of words. These works were critical to the preservation of the Vedic texts, as well as the accurate ritual recitations and analyses of the Vedas, particularly when isolated words interact after they have been joined in sandhi procedures. Each Vedic school and geographic branch (sakha) developed their own manuals, explaining why they have come to be called parsada or pratisakhya.

Prodromus Coptus sive Aegyptiacus was a 1636 work by the Jesuit scholar Athanasius Kircher. It was published in Rome by the Sacred Congregation for the Propagation of the Faith and dedicated to the Prefect of the Congregation, Cardinal Francesco Barberini. The book was Kircher's first venture into the field of Egyptology, and it also contained the first ever published grammar of the Coptic language.
