“Tupian” is a common term applied by linguists to a linguistic stock of seven families spread across great parts of South America. Tupian languages share a large number of structural and morphological similarities which make genetic relationship very probable. Four families (Arikém, Mondé, Tuparí, and Raramarama-Poruborá) are still limited to the Madeira-Guaporé region in Brazil, considered by some scholars to be the Tupí homeland. Other families and branches would have migrated, in ancient times, down the Amazon (Mundurukú, Mawé) and up the Xingú River (Juruna, Awetí). Only the Tupí-Guarani branch, which makes up about 40 living languages, mainly spread to the south. Two Tupí-Guaraní languages played an important part in the Portuguese and Spanish colonisation of South America, Tupinambá on the Brazilian coast and Guaraní in colonial Paraguay. In the early 21st century, Guaraní is spoken by more than six million non-Indian people in Paraguay and in adjacent parts of Argentina and Brazil. Tupí-Guaraní (TG) is an artificial term used by linguists to denominate the family composed by eight subgroups of languages, one of them being the Guaraní subgroup and the other one the extinct Tupinambá and its varieties. Important phonological characteristics of Tupian languages are nasality and the occurrence of a high central vowel /ɨ/, a glottal stop /ʔ/, and final consonants, especially plosives in coda position. Nasality seems to be a common characteristic of all branches of the family. Most of them show phenomena such as nasal harmony, also called nasal assimilation or regressive nasalization by some scholars. Tupian languages have a rich morphology expressed mainly by suffixes and prefixes, though particles are also important to express grammatical categories. Verbal morphology is characterized by generally rich devices of valence-changing formations. Relational inflection is one of the most striking phenomena of TG nominal phrases. It allows marking the determination of a noun by a preceding adjunct, its syntactical transformation into a nominal predicate, or the absence of any relation. Relational inflection partly occurs also in other branches and families than Tupí-Guaraní. Verbal person marking is realized by prefixing in most languages; some languages of the Tuparí and Juruna family, however, use only free pronouns. Tupian syntax is based on the predication of both verbs and nouns. Subordinate clauses, such as relative clauses, are produced by nominalization, while adverbial clauses are formed by specific particles or postpositions on the predicate. Traditional word order is SOV.
Dene languages are often recognized for their morphological complexity. The languages are known in particular for their complex verbal morphology, and the Dene verb word has received considerable attention in the literature. The verb word is polysynthetic, with several unusual properties: the actual morpheme inventory is relatively small, with rich word formation possibilities; it is prefixing, while suffixing is far more common amongst the world’s languages; what is a single morpheme from a semantic perspective can be discontinuous, illustrating what Whorf calls interrupted synthesis; a single morpheme can be both semantically productive and lexically idiosyncratic; some affixes are mobile; there is considerable homophony; fusion of morphemes is common; and aspects of the phonology lead to surface opacity, with unexpected allomorphy. Several proposals have been introduced to account for the structure of the verb word, and psycholinguistic and sociolinguistic factors that enter in to understanding the complexities of the verb word have been addressed. There is also research on the acquisition of and teaching of the verb word. Overall, it is important to ask what the structure of the verb is synchronically, and what, while interesting, is a consequence of diachronic developments. In addition to the well-studied complexities of the verb, there are also interesting aspects of other categories. The nouns are worthy of attention for their formation, a noun classification system, and nominal possession. The directional systems of Dene languages tend to be rich, including both a root that indicates direction and a prefix that specifies distance or direction from the speaker. At least some of he languages also have evidentials, and these are, in general, understudied. Dene languages, like many other languages of North America, are now being learned largely as second languages. This increases the urgency to study areas such as acquisition and language use in order to help in sustaining the languages in communities where this is desired.
The five languages of the Northwest Caucasian family (also known as West Caucasian or Abkhaz-Adyghe), namely West Circassian, Kabardian, Ubykh, Abkhaz, and Abaza, are remarkable for their high degree of polysynthesis. This manifests itself in complex words that bear a lot of information on arguments and the characteristics of a situation, and which presumably can be constructed in the course of speech. Content words usually consist of several morphological zones within which certain permutations of morphemes are possible. Both prefixes and suffixes occur, with some morphemes being capable of appearing either as a prefix or a suffix, depending on the form. The predicate shows ergative-based cross-reference of core arguments and indirect objects introduced by applicatives, extensive use of the causative (including double causativization), highly developed means of expressing locational semantics within the predicate, and intricate tense-modality-aspect and polarity systems. Although classical noun-to-verb incorporation does not occur, there are constructions akin to incorporation, especially in the nominal domain. Nouns constitute a subclass of a broad class of predicates (both morphologically and syntactically) and hence may take the basic predicate morphology. At the same time, they form word-like nominal complexes with their attributes, and show specific head-marking possessive morphology (in West Circassian even distinguishing alienable and inalienable possession). Definiteness/specificity is regularly expressed either by articles (in Abkhaz, Abaza and Ubykh) or by the presence/absence of core case marking (in West Circassian and Kabardian). Morphemes demonstrate features that are not typical of morphemes in Standard Average European languages, including a high degree of autonomy reflected in affix order variation, widespread morphological recursion, occasional reduplication and even the ability to attach to complex syntactic constituents.

Sino-Tibetan is a highly diverse language family, in which a wide range of morphological phenomena and profiles may be found. The family is generally seen as split into two major branches, i.e., Sinitic and Tibeto-Burman, but while Sinitic is a fairly homogeneous group in terms of morphology, the so-called Tibeto-Burman branch of the family includes isolating languages like Karen, languages with transparent and regular agglutinative morphology (Lolo-Burmese, Tibetic, and Boro-Garo), but also paradigmatically complex languages, with elaborate argument indexation and transitivity management systems; while in some languages morphological complexity is mostly a conservative trait (e.g., Rgyalrongic and Kiranti), other languages developed innovative paradigms, with only few vestiges of the archaic system (Kuki-Chin). Some notable morphological phenomena in modern Tibeto-Burman languages are verb stem alternation, peculiar nominalization constructions, and long sequences of prefixes, which in some languages (Chintang) may even be freely permutated without any relevant change in meaning. Also, while Sinitic languages are normally taken to be a prototypical example of the (ideal) isolating morphological type (with virtually no inflection, stable morpheme boundaries, no cumulative exponence, and no allomorphy or suppletion), phenomena of strong reduction of morphemes, blurring of morpheme boundaries and fusion between root and suffix, and nonconcatenative morphology, as well as allomorphy and (proto-)paradigmatic organization of morphology, are attested in some Chinese dialects, mostly concentrated in an area of Northern China (Shaanxi, Shanxi, Henan, Hebei, and Shandong provinces). Moreover, ‘Altaic-type’ agglutinative morphology, including case marking, is found in Sinitic languages of the so-called Qinghai-Gansu Sprachbund; in this case, the development of agglutination, as well as other typological traits (as SOV word order), is clearly the product of intense and prolonged contact between Northwestern Chinese dialects and Tibetic and Mongolic languages of China. On the other hand, Southern Chinese dialects have developed in closer contact with Hmong-Mien, Tai-Kadai, and Austroasiatic languages, and are thus closer to the typology of Mainland Southeast Asian languages, with a very strong isolating profile.
While in phonology Middle Indo-Aryan (MIA) dialects preserved the phonological system of Old Indo-Aryan (OIA) virtually intact, their morphosyntax underwent far-reaching changes, which altered fundamentally the synthetic morphology of earlier Prākrits in the direction of the analytic typology of New Indo-Aryan (NIA). Speaking holistically, the “accusative alignment” of OIA (Vedic Sanskrit) was restructured as an “ergative alignment” in Western IA languages, and it is precisely during the Late MIA period (ca. 5th–12th centuries ce) when we can observe these matters in statu nascendi. There is copious literature on the origin of the ergative construction: passive-to-ergative reanalysis; the ergative hypothesis, i.e., that the passive construction of OIA was already ergative; and a compromise stance that neither the former nor the latter approach is fully adequate. In the spirit of the complementary view of these matters, more attention has to be paid to various pathways in which typological changes operated over different kinds of nominal, pronominal and verbal constituents during the crucial MIA period. (a) We shall start with the restructuring of the nominal case system in terms of the reduction of the number of cases from seven to four. This phonologically motivated process resulted ultimately in the rise of the binary distinction of the “absolutive” versus “oblique” case at the end of the MIA period). (b) The crucial role of animacy in the restructuring of the pronominal system and the rise of the “double-oblique” system in Ardha-Māgadhī and Western Apabhramśa will be explicated. (c) In the verbal system we witness complete remodeling of the aspectual system as a consequence of the loss of earlier synthetic forms expressing the perfective (Aorist) and “retrospective” (Perfect) aspect. Early Prākrits (Pāli) preserved their sigmatic Aorists (and the sigmatic Future) until late MIA centuries, while on the Iranian side the loss of the “sigmatic” aorist was accelerated in Middle Persian by the “weakening” of s > h > Ø. (d) The development and the establishment of “ergative alignment” at the end of the MIA period will be presented as a consequence of the above typological changes: the rise of the “absolutive” vs. “oblique” case system; the loss of the finite morphology of the perfective and retrospective aspect; and the recreation of the aspectual contrast of perfectivity by means of quasinominal (participial) forms. (e) Concurrently with the development toward the analyticity in grammatical aspect, we witness the evolution of lexical aspect (Aktionsart) ushering in the florescence of “serial” verbs in New Indo-Aryan. On the whole, a contingency view of alignment considers the increase in ergativity as a by-product of the restoration of the OIA aspectual triad: Imperfective–Perfective–Perfect (in morphological terms Present–Aorist–Perfect). The NIA Perfective and Perfect are aligned ergatively, while their finite OIA ancestors (Aorist and Perfect) were aligned accusatively. Detailed linguistic analysis of Middle Indo-Aryan texts offers us a unique opportunity for a deeper comprehension of the formative period of the NIA state of affairs.
