This paper reopens the discussion on focus marking in Akan (Kwa,
Niger-Congo) by examining the semantics of the so-called focus marker
in the language. It is shown that the so-called focus marker expresses
exhaustivity when it occurs in a sentence with narrow focus. The study
employs four standard tests for exhaustivity proposed in the literature
to examine the semantics of Akan focus constructions (Szabolsci 1981,
1994; É. Kiss 1998; Hartmann and Zimmermann 2007). It is shown that
although a focused entity with the so-called focus marker nà is
interpreted to mean ‘only X and nothing/nobody else,’ this meaning
appears to be pragmatic.
Cleft exhaustivity
(2020)
In this dissertation a series of experimental studies are presented which demonstrate that the exhaustive inference of focus-background it-clefts in English and their cross-linguistic counterparts in Akan, French, and German is neither robust nor systematic. The inter-speaker and cross-linguistic variability is accounted for with a discourse-pragmatic approach to cleft exhaustivity, in which -- following Pollard & Yasavul 2016 -- the exhaustive inference is derived from an interaction with another layer of meaning, namely, the existence presupposition encoded in clefts.
This dissertation is about factors that contribute to the surface forms of tones in connected speech in Akan. Akan is an African tone language, which is spoken in Ghana. It has two level tones (low and high), automatic and non-automatic downstep. Downstep is the major factor that influences the surface forms of tones. The thesis shows that downstep is caused by declination. It is argued that declination is an intonational property of Akan, which serves to signal coherence. A phonological representation using a high and a low register tone, associating to the left and right edge of an intonational phrase (IP), respectively, is proposed. Declination/downstep is modelled using a (phonetic) pitch implementation algorithm (Liberman & Pierrehumbert, 1984). An innovative application of the algorithm is presented, which naturally captures the relation between declination and downstep in Akan. Another important factor is the prosodic manifestation of sentence level pragmatic meanings, such as sentence mode and focus. Regarding the former, the thesis shows that a post-lexical low tone, which associates with the right edge of an IP, signals interrogativity. Additionally, lexical tones in Yes – No questions are realized in a higher pitch register, which does not lead to a reduction of declination. It is claimed that the higher register is not part of the phonological representation in Akan, but that it emerges at the phonetic level to compensate for the ‘unnatural’ form of the question morpheme and to satisfy the Frequency code (Gussenhoven, 2002; 2004). An extension of Rialland’s (2007) typology in terms of a new category called “low tense” question prosody is proposed. Concerning focus marking, it is argued that the use of the morpho-syntactic focus marking strategy is related to extra grammatical factors, such as hearer expectation, discourse expectability (Zimmermann, 2007) and emphasis (Hartmann, 2008). If a speaker of Akan wants to highlight a particular element in a sentence, in-situ, i.e. by means of prosody, the default prosodic structure is modified in such a way that the focused element forms its own phonological phrase (pP). If it is already contained in a pP, the boundary deliminating the focused element is enhanced (Féry, 2012). This restructuring/enhancement is accompanied by an interruption of the otherwise continuous melody due to insertion of a pause and/or a glottal stop. Beside declination and intonation, raising of H tones applies in Akan. H raising is analyzed as a local anticipatory planning effect, employed at the phonetic level, which enhances the perceptual distance between low and high tones. Low tones are raised, if they are wedged between two high tones. L raising is argued to be a local carryover effect (co-articulation). Further, it is demonstrated that global anticipatory raising takes place. It is shown that Akan speakers anticipate the length of an IP. Preplanning (anticipatory raising) is argued to be an important process at the level of pitch implementation. It serves to ensure that declination can be maintained throughout the IP, which prevents pitch resetting.
The melody of an Akan sentence is largely determined by the choice of words. The inventory of post-lexical tones is small. It consists of post-lexical register tones, which trigger declination and post-lexical intonational tones, which signal sentence type. The overall melodic shape is falling. At the local level, H raising and L raising occur. At the global level, initial low and high tones are realized higher if they occur in a long and/or complex sentence. This dissertation shows that many factors, which emerge at different levels of the tone production process, contribute to the surface form of tones in Akan.
This article presents a situation description production experiment investigating the interaction between syntax and information structure in Akan, a tone language that belongs to the Kwa branch of the Niger- Congo family spoken in Ghana. Information structure was elicited via context questions that put the object in narrow informational focus or narrow corrective focus while controlling for the tonal structure of the target word. Contrary to the prediction that corrective focus is marked by fronting and morphological marking of the focused constituent the data suggest that the in-situ strategy is the preferred one.
This is the 13th issue of the working paper series Interdisciplinary Studies on Information Structure (ISIS) of the Sonderforschungsbereich (SFB) 632. It is the first part of a series of Linguistic Fieldnote issues which present data collected by members of different projects of the SFB during fieldwork on various languages or dialects spoken worldwide. This part of the Fieldnote Series is dedicated to data from African languages. It contains contributions by Mira Grubic (A5) on Ngizim, and Susanne Genzel & Frank Kügler (D5) on Akan. The papers allow insights into various aspects of the elicitation of formal correlates of focus and related phenomena in different African languages investigated by the SFB in the second funding phase, especially in the period between 2007 and 2010.
This article presents data from three production experiments investigating the prosodic means of encoding information structure in Akan, a tone language that belongs to the Kwa branch of the Niger-Congo family, spoken in Ghana. Information structure was elicited via context questions that put target words either in wide, informational, or corrective focus, or in one of the experiments also in pre-focal or post-focal position rendering it as given. The prosodic parameters F0 and duration were measured on the target words. Duration is not consistently affected by information structure, but contrary to the prediction that High (H) and Low (L) tones are raised in ex situ (fronted) focus constructions we found a significantly lower realization of both H and L tones under corrective focus in ex situ and in situ focus constructions. Givenness does not seem to be marked prosodically. The data suggest that pragmatic prominence is expressed prosodically by means of a deviation from an unmarked prosodic structure. Results are thus contradicting the view of the effort code that predicts a positive correlation of more effort resulting in higher F0 targets.
Background: The distribution of pronouns varies cross-linguistically. This distribution has led to conflicting results in studies that investigated pronoun resolution in agrammatic indviduals. In the investigation of pronominal resolution, the linguistic phenomenon of "resumption" is understudied in agrammatism. The construction of pronominal resolution in Akan presents the opportunity to thoroughly examine resumption. Aims: To start, the present study examines the production of (pronominal) resumption in Akan focus constructions (who-questions and focused declaratives). Second, we explore the effect of grammatical tone on the processing of pronominal (resumption) since Akan is a tonal language. Methods & Procedures: First, we tested the ability to distinguish linguistic and non-linguistic tone in Akan agrammatic speakers. Then, we administered an elicitation task to five Akan agrammatic individuals, controlling for the structural variations in the realization of resumption: focused who-questions and declaratives with (i) only a resumptive pronoun, (ii) only a clause determiner, (iii) a resumptive pronoun and a clause determiner co-occurring, and (iv) neither a resumptive pronoun nor a clause determiner. Outcomes & Results: Tone discrimination .both for pitch and for lexical tone was unimpaired. The production task demonstrated that the production of resumptive pronouns and clause determiners was intact. However, the production of declarative sentences in derived word order was impaired; wh-object questions were relatively well-preserved. Conclusions: We argue that the problems with sentence production are highly selective: linguistic tones and resumption are intact but word order is impaired in non-canonical declarative sentences.
Acquiring Syntactic Variability: The Production of Wh-Questions in Children and Adults Speaking Akan
(2020)
This paper investigates the predictions of the Derivational Complexity Hypothesis by studying the acquisition of wh-questions in 4- and 5-year-old Akan-speaking children in an experimental approach using an elicited production and an elicited imitation task. Akan has two types of wh-question structures (wh-in-situ and wh-ex-situ questions), which allows an investigation of children’s acquisition of these two question structures and their preferences for one or the other. Our results show that adults prefer to use wh-ex-situ questions over wh-in-situ questions. The results from the children show that both age groups have the two question structures in their linguistic repertoire. However, they differ in their preferences in usage in the elicited production task: while the 5-year-olds preferred the wh-in-situ structure over the wh-ex-situ structure, the 4-year-olds showed a selective preference for the wh-in-situ structure in who-questions. These findings suggest a developmental change in wh-question preferences in Akan-learning children between 4 and 5 years of age with a so far unobserved u-shaped developmental pattern. In the elicited imitation task, all groups showed a strong tendency to maintain the structure of in-situ and ex-situ questions in repeating grammatical questions. When repairing ungrammatical ex-situ questions, structural changes to grammatical in-situ questions were hardly observed but the insertion of missing morphemes while keeping the ex-situ structure. Together, our findings provide only partial support for the Derivational Complexity Hypothesis.
It has been observed for many African languages that focussed subjects
have to appear outside of their syntactic base position, as opposed to
focussed objects, which can remain in-situ. This is known as subjectobject
asymmetry of focus marking, which Fiedler et al. (2010) claim
to hold also for Akan. Genzel (2013), on the other hand, argues that
Akan does not exhibit a subject-object focus asymmetry. A questionnaire
study and a production experiment were carried out to investigate
whether focussed subjects may indeed be realized in-situ in Akan. The
results suggest that (i) focussed subjects do not have to be obligatorily
realized ex-situ, and that (ii) the syntactic preference for the realization
of a focussed subject highly depends on exhaustivity.
