“Altaic” is a common term applied by linguists to a number of language families, spread across Central Asia and the Far East and sharing a large, most likely non-coincidental, number of structural and morphemic similarities. At the onset of Altaic studies, these similarities were ascribed to the one-time existence of an ancestral language—“Proto-Altaic,” from which all these families are descended; circumstantial evidence and glottochronological calculations tentatively date this language to some time around the 6th–7th millennium bc, and suggest Southern Siberia or adjacent territories (hence the name “Altaic”) as the original homeland of its speakers. However, since the mid-20th century the dominant view in historical linguistics has shifted to that of an “Altaic Sprachbund” (diffusion area), implying that the families in question have not sprung from a common source, but rather have acquired their similarities over a long period of mutual linguistic contact. The bulk of “Altaic” has traditionally included such uncontroversial families as Turkic, Mongolic, and Manchu-Tungusic; additionally, Japanese (Japonic) and Korean are also frequently seen as potential members of the larger Altaic family (the entire five branches are sometimes referred to as “Macro-Altaic”). The debate over the nature of the relationship between the various units that constitute “Altaic,” sometimes referred to as “the Altaic controversy,” has been one of the most hotly debated topics in 20th-century historical linguistics and a major focal point of studies dealing with the prehistory of Central and East Eurasia. Supporters of “Proto-Altaic,” commonly known as “(pro-)Altaicists,” claim that only divergence from an original common ancestor can account for the observed regular phonetic correspondences and other structural similarities, whereas “anti-Altaicists,” without denying the existence of such similarities, insist that they do not belong to the “core” layers of the respective languages and are therefore better explained as results of lexical borrowing and other forms of areal linguistic contact. As a rule, “pro-Altaicists” claim that “Proto-Altaic” is as reconstructible by means of the classic comparative method as any uncontroversial linguistic family; in support of this view, they have produced several attempts to assemble large bodies of etymological evidence for the hypothesis, backed by systems of regular phonetic correspondences between compared languages. All of these, however, have been heavily criticized by “anti-Altaicists” for lack of methodological rigor, implausibility of proposed phonetic and/or semantic changes, and confusion of recent borrowings with items allegedly inherited from a common ancestor. Despite the validity of many of these objections, it remains unclear whether they are sufficient to completely discredit the hypothesis of a genetic connection between the various branches of “Altaic,” which continues to be actively supported by a small, but stable scholarly minority.
Dene-Yeniseian is a proposed genealogical link between the widespread North American language family Na-Dene (Athabaskan, Eyak, Tlingit) and Yeniseian in central Siberia, represented today by the critically endangered Ket and several documented extinct relatives. The Dene-Yeniseian hypothesis is an old idea, but since 2006 new evidence supporting it has been published in the form of shared morphological systems and a modest number of lexical cognates showing interlocking sound correspondences. Recent data from human genetics and folklore studies also increasingly indicate the plausibility of a prehistoric (probably Late Pleistocene) connection between populations in northwestern North America and the traditionally Yeniseian-speaking areas of south-central Siberia. At present, Dene-Yeniseian cannot be accepted as a proven language family until the purported evidence supporting the lexical and morphological correspondences between Yeniseian and Na-Dene is expanded and tested by further critical analysis and their relationship to Old World families such as Sino-Tibetan and Caucasian, as well as the isolate Burushaski (all earlier proposed as relatives of Yeniseian, and sometimes also of Na-Dene), becomes clearer.
Kra-Dai, also known as Tai–Kadai, Daic, and Kadai, is a family of diverse languages found in southern China, northeast India, and Southeast Asia. The number of these languages is estimated to be close to a hundred, with approximately 100 million speakers all over the world. As the name itself suggests, Kra-Dai is made up of two major groups, Kra and Dai. The former refers to a number of lesser-known languages, some of which have only a few hundred fluent speakers or even less. The latter (also known as Tai, or Kam-Tai) is well established, and comprises the best-known members of the family, Thai and Lao, the national languages of Thailand and Laos respectively, whose speakers account for over half of the Kra-Dai population. The ultimate genetic affiliation of Kra-Dai remains controversial, although a consensus among western scholars holds that it belongs under Austronesian. The majority of Kra-Dai languages have no writing systems of their own, particularly Kra. Languages with writing systems include Thai, Lao, Sipsongpanna Dai, and Tai Lue. These use Indic-based scripts. Others use Chinese character-based scripts, such as the Zhuang and Kam-Sui in southern China and surrounding regions. The government introduced Romanized scripts in the 1950s for the Zhuang and the Kam-Sui languages. Almost every group within Kra-Dai has a rich oral history tradition. The languages are typically tonal, isolating, and analytic, lacking in inflectional morphology, with no distinction for number and gender. A significant number of basic vocabulary items are monosyllabic, but bisyllabic and multisyllabic compounds also abound. There are morphological processes in which etymologically related words manifest themselves in groups through tonal, initial, or vowel alternations. Reduplication is a salient word formation mechanism. In syntax, the Kra-Dai languages can be said to have basic SVO word order. They possess a rich system of noun classifiers. Other features include verb serialization without overt marking to indicate grammatical relations. A number of lexical items (mostly verbs) may function as grammatical morphemes in syntactic operations. Temporal and aspectual meanings are expressed through tense-aspect markers typically derived from verbs, while mood and modality are conveyed via a rich array of discourse particles.

Etymology is the only linguistic subdiscipline that is uniquely historical in its study of the relevant linguistic data and one of the oldest fields in Romance linguistics. The concept of etymology as practiced by Romanists has changed over the last 100 years. At the outset, Romance etymologists took as their brief the search for and identification of individual word origins. Starting in the early 20th century, various specialists began to view etymology as the preparation of the complete history of all facets of the evolution over time and space of the words or lexical families being studied. Identification of the underlying base was only the first step in the process. From this perspective, etymology constitutes an essential element of diachronic lexicology, which covers all formal, semantic, and syntactic facets of a word’s evolution, including, if appropriate, the circumstances leading to its demise and replacement.
