Negation of Sentence Types in Nsukwa Dialect of Igbo

Dugbo, L. I.  Negation of Sentence Types in Nsukwa Dialect of Igbo Afrisophia: Journal of African Experiment, Thought and Experience, Vol. 3, No. 2, pp. 12–26.   doi.org   Abstract This study investigates the negation of sentence types in the Nsukwa dialect of the Igbo language. The research focuses on identifying the different forms of negation and describing how negative sentences are constructed within the dialect. Data were collected through oral interviews with nine competent native speakers of Nsukwa, supported by relevant secondary sources. The analysis adopts Dixon’s (2009) Basic Linguistic Theory as its framework, using descriptive methods to analyse structural and tonal patterns in negation. Findings reveal that negation in Nsukwa operates through a system of affixation and tonal variation, with specific negative markers attached either as prefixes or suffixes to verbs depending on the subject type and sentence function. The study identifies several types of negation across sentence forms, including indicative, progressive, future, unfulfilled, hortative, and perfective sentences. The general negative marker =ne/na is suffixed to verbs in indicative constructions, while di combines with ne/na to form progressive negatives. The future negative is marked by ma, expressing futurity denial, whereas unfulfilled negatives employ ka with a negation suffix. The results indicate that tone plays a crucial role in distinguishing meaning between affirmative and negative sentences. The study concludes that negation in Nsukwa follows systematic morphological and syntactic rules consistent with broader Igbo grammar but retains dialectal peculiarities in tone and affix placement.   Keywords: Nsukwa dialect, Igbo, negation, syntax, semantics, pragmatics
