Etymology studies the history of words: when they entered a language, from what source, and how their form and meaning have changed over time. Words may enter a language in several ways, including being borrowed as loanwords from another language, being derived by combining pre-existing elements in the language, by a hybrid known as phono ...
The highly diverse Nilo-Saharan languages, first proposed as a family by Joseph Greenberg in 1963 might have originated in the Upper Paleolithic. [1] Given the presence of a tripartite number system in modern Nilo-Saharan languages, linguist N.A. Blench inferred a noun classifier in the proto-language, distributed based on water courses in the Sahara during the "wet period" of the Neolithic ...
The origin of language, its relationship with human evolution, and its consequences have been subjects of study for centuries.Scholars wishing to study the origins of language draw inferences from evidence such as the fossil record, archaeological evidence, contemporary language diversity, studies of language acquisition, and comparisons between human language and systems of animal ...
Some scholars assume the development of primitive language-like systems (proto-language) as early as Homo habilis (2.3 million years ago) while others place the development of primitive symbolic communication only with Homo erectus (1.8 million years ago) or Homo heidelbergensis (0.6 million years ago), and the development of language proper ...
Thus, historical languages contrast with dead languages (languages which have become extinct, or undergone language death). Also, historical languages contrast with reconstructed languages (that is, the proto-languages) of theoretical linguistics. One of the approaches to defining and using the concept of historical languages is implemented in ...
Linguistics is the scientific study of language, [1] involving analysis of language form, language meaning, and language in context. [2]Language use was first systematically documented in Mesopotamia, with extant lexical lists of the 3rd to the 2nd Millennia BCE, offering glossaries on Sumerian cuneiform usage and meaning, and phonetical vocabularies of foreign languages.
Based on studies of the developing visual system by Torsten Wiesel and David Hubel, [30] it has been suggested that the environment guides the development of language networks in the brain by selecting the neurons and their synapses that are most active during the prolonged early development of humans in a socio-linguistic environment.

An attested word from which a root in the proto-language is reconstructed is a reflex. More generally, a reflex is the known derivative of an earlier form, which may be either attested or reconstructed. A reflex that is predictable from the reconstructed history of the language is a 'regular' reflex. Reflexes of the same source are cognates.
