This is the first broad, detailed grammar of the Giziga language, which belongs to the Chadic branch of the Afro-Asiatic language family and is spoken in parts of the Far North Region of the Republic of Cameroon.

Wandala is a hitherto undescribed Central Chadic language spoken in Northern Cameroon and Northeastern Nigeria. The Grammar of Wandala describes, in a non-aprioristic approach, phonology, morphology, syntax, and all functional domains grammaticalized in the language. The grammatical structure of Wandala is quite different from the structure of other Chadic languages described thus far in both the formal means and the functions that have been grammaticalized. The grammar provides proofs for the postulated hypotheses concerning forms and functions. The grammar is written in a style accessible to linguists working within different theoretical frameworks. The phonology is characterized by a rich consonantal system, a three vowel system, and a two tone system. The language has abundant vowel insertion rules and a vowel harmony system. Vowel deletion marks phrase-internal position, and vowel-insertion marks phrase-final position. The two rules allow the parsing of the clause into constituents. The language has three types of reduplication of verbs, two of which code aspectual and modal distinctions. The negative paradigms of verbs differ from affirmative paradigms in the coding of subject. The pronominal affixes and extensive system of verbal extensions code the grammatical and semantic relations within the clause. Wandala has unusual clausal structure, in that in a pragmatically neutral verbal clause, there is only one nominal argument, either the subject or the object. These arguments can follow a variety of constituents. The grammatical role of that argument is coded by inflectional markers on the verb and most interestingly, on whatever lexical or grammatical morpheme precedes the constituent. The markers of grammatical relations added to verbs are different for different classes of verbs.

In 1991, William Croft suggested that negative existentials (typically lexical expressions that mean ‘not exist, not have’) are one possible source for negation markers and gave his hypothesis the name Negative Existential Cycle (NEC). It is a variationist model based on cross-linguistic data. For a good twenty years following its formulation, it was cited at face-value without ever having been tested by (historical)-comparative data. Over the last decade, Ljuba Veselinova has worked on testing the model in a comparative perspective, and this edited volume further expands on her work. The collection presented here features detailed studies of several language families such as Bantu, Chadic and Indo-European. A number of articles focus on the micro-variation and attested historical developments within smaller groups and clusters such as Arabic, Mandarin and Cantonese, and Nanaic. Finally, variation and historical developments in specific languages are discussed for Ancient Hebrew, Ancient Egyptian, Moksha-Mordvin (Uralic), Bashkir (Turkic), Kalmyk (Mongolic), three Pama-Nyungan languages, O’dam (Southern Uto-Aztecan) and Tacana (Takanan, Amazonian Bolivia). The book is concluded by two chapters devoted to modeling cyclical processes in language change from different theoretical perspectives. Key notions discussed throughout the book include affirmative and negative existential constructions, the expansion of the latter into verbal negation, and subsequently from more specific to more general markers of negation. Nominalizations as well as the uses of negative existentials as standalone negative answers figure among the most frequent pathways whereby negative existentials evolve as general negation markers. The operation of the Negative Existential Cycle appears partly genealogically conditioned, as the cycle is found to iterate regularly within some families but never starts in others, as is the case in Bantu. In addition, other special negation markers such as nominal negators are found to undergo similar processes, i.e. they expand into the verbal domain and thereby develop into more general negation markers. The book provides rich information on a specific path of the evolution of negation, on cyclical processes in language change, and it show-cases the historical-comparative method in a modern setting.

The Oxford Handbook of Derivational Morphology is intended as a companion volume to The Oxford Handbook of Compounding (OUP 2009) Written by distinguished scholars, its 41 chapters aim to provide a comprehensive and thorough overview of the study of derivational morphology. The handbook begins with an overview and a consideration of definitional matters, distinguishing derivation from inflection on the one hand and compounding on the other. From a formal perspective, the handbook treats affixation (prefixation, suffixation, infixation, circumfixation, etc.), conversion, reduplication, root and pattern and other templatic processes, as well as prosodic and subtractive means of forming new words. From a semantic perspective, it looks at the processes that form various types of adjectives, adverbs, nouns, and verbs, as well as evaluatives and the rarer processes that form function words. The book also surveys derivation in fifteen language families that are widely dispersed in terms of both geographical location and typological characteristics.

In A Grammar of Lopit, Jonathan Moodie and Rosey Billington provide a detailed description of the phonology, morphology, and syntax of Lopit, an Eastern Nilotic language traditionally spoken in the Lopit Mountains in South Sudan.

"In A Grammar of Makary Kotoko, Sean Allison provides a thorough description and analysis of Makary Kotoko - a Central Chadic language of Cameroon, framing the discussion within R.M.W. Dixon's (2010a, 2010b, 2012) Basic Linguistic Theory. Working with an extensive corpus of recorded texts supplemented by interactions with native speakers of the language, the author provides the first full grammar of a Kotoko language. The detailed analysis of the phonology, morphology, syntax, and discourse features of Makary Kotoko is from a functional/typological perspective. Being based on a large number of oral texts, the analysis provides an example-rich description showing the range of variation of the constructions presented while giving insights into Kotoko culture"--

This volume contains 14 descriptive chapters and a collection of 4 transcribed texts in Mursi, a highly endangered language spoken in the Lower Omo Valley in Ethiopia.
