Relativiser Alternation and Relative Clause Complexity: Insights from Nigerian and American Varieties

Abstract

Idiosyncrasies and peculiarities distinguishing new Englishes from the established ones are often identifi ed and measured by examining the extent to which structural choices and patterns vary across the board. The competition between relativisers whand that in the construction of relative clause, which itself is a structurally complex-versus-simple construction site, allows for showing the extent to which choice of a relativiser relates to the construction of a complex or simple relative clause, given diff erent factors. On the other hand, such investigation can also shed some light on the extent to which structural complexity characterises new varieties of English. Relying on 628 relative clauses drawn from written academic corpus, the study shows that WH-relativiser is preferred to THAT-relativiser by the Nigerian speakers, and vice versa by the American speakers. It is also found that WH-relative clause is more likely to be complex-structured while THAT-relative clause is more likely to be simple-structured. Among eight factors tested for independent eff ects, the factors representing relativiser posterior syntactic form, syntactic function, and syntactic positioning of the relative clause appeared to be strong predictors of where we might (not) fi nd a certain relativiser and whether a complex or simple relative clause will emerge.
