The article appraises gender representation in the 1999 Nigerian Constitution using insights from critical discourse analysis, feminism and systemic functional linguistics, with particular emphasis on grammatical cohesion. Specifically, it examines lexical and grammatical expressions that encode gender in the Constitution, the ideological positions evident in these expressions, and their impact on gender parity and socio-political equity. The focus is on the reference-antecedent cohesion of gender-marked pronouns and nouns used to refer to individuals and social/political positions. Our findings show a preponderance of generic masculine noun and pronoun references, tracking antecedents that refer to social and political positions open to eligible individuals in Nigeria, while the single feminine referent was a marked case. These findings buttress the ‘male-as-norm’ ideology and the relegation to anonymity of the female gender in this important national document. For equity and fairness, the article recommends revising the Constitution with epicene expressions to expunge gender biases.
