Macrofamily
In historical linguistics, a macrofamily, also called a superfamily or phylum, is a proposed genetic relationship grouping together language families (also isolates) in a larger scale classification. However, Campbell regards this term as superfluous, preferring "language family" for those classifications for which there is consensus and "distant genetic relationship" for those for which there is no, or not yet, consensus, whether due to lack of documentation or scholarship of the constituent languages, or to an estimated time depth thought by many linguists to be too great for reconstruction.
Glottochronology
Glottochronology (from Attic Greek γλῶττα tongue, language and χρόνος time) is the part of lexicostatistics which involves comparative linguistics and deals with the chronological relationship between languages. The idea was developed by Morris Swadesh in the 1950s in his article on Salish internal relationships. He developed the idea under two assumptions: there indeed exists a relatively stable basic vocabulary (referred to as Swadesh lists) in all languages of the world; and, any replacements happen in a way analogous to radioactive decay in a constant percentage per time elapsed.
Language convergence
Language convergence is a type of linguistic change in which languages come to resemble one another structurally as a result of prolonged language contact and mutual interference, regardless of whether those languages belong to the same language family, i.e. stem from a common genealogical proto-language. In contrast to other contact-induced language changes like creolization or the formation of mixed languages, convergence refers to a mutual process that results in changes in all the languages involved.
Conservative and innovative (linguistics)
In linguistics, a conservative form, variety, or feature of a language is one that has changed relatively little across the language's history, or which is relatively resistant to change. It is the opposite of innovative, innovating, or advanced forms, varieties, or features, which have undergone relatively larger or more recent changes. Furthermore, an archaic form is not only chronologically old (and often conservative) but also rarely used anymore in the modern language, and an obsolete form has fallen out of use altogether.
Attested language
In linguistics, attested languages are languages (living or dead) that have been documented and for which the evidence (“attestation”) has survived to the present day. Evidence may be recordings, transcriptions, literature or inscriptions. In contrast, unattested languages may be names of purported languages for which no direct evidence exists, languages for which all evidence has been lost, or hypothetical proto-languages proposed in linguistic reconstruction.
Swadesh list
The Swadesh list (ˈswɑːdɛʃ) is a classic compilation of tentatively universal concepts for the purposes of lexicostatistics. Translations of the Swadesh list into a set of languages allow researchers to quantify the interrelatedness of those languages. The Swadesh list is named after linguist Morris Swadesh. It is used in lexicostatistics (the quantitative assessment of the genealogical relatedness of languages) and glottochronology (the dating of language divergence).
Diaphoneme
A diaphoneme is an abstract phonological unit that identifies a correspondence between related sounds of two or more varieties of a language or language cluster. For example, some English varieties contrast the vowel of late (/eː/) with that of wait or eight (/ɛɪ/). Other English varieties contrast the vowel of late or wait (/eː/) with that of eight (/ɛɪ/). This non-overlapping pair of phonemes from two different varieties can be reconciled by positing three different diaphonemes: A first diaphoneme for words like late (⫽e⫽), a second diaphoneme for words like wait (⫽ei⫽), and a third diaphoneme for words like eight (⫽ex⫽).
