This chapter presents the negative constructions of Beja, a North-Cushitic (Afroasiatic)language, which are basically asymmetrical. It discusses in turn (i) standardnegation in declarative main clauses with A/Cat/TAM asymmetry; (ii) the twonegative types in non-declaratives, one of which does not use a negator but stemalternation and specific inflection; (iii) negation in non-main clauses (even moreasymmetrical than declaratives); (iv) privatives, which include one case of clausechaining instead of a negator; (v) phasal polarity expressions; (vi) negation in stative predications; (vii) negative replies and their pragmatics. It also discusses theabsence of negative transport, as well as of negative indefinites and the strategiesused instead.
