Research on complementizer selection has shown that the presence of a negative particle in a subordinate complement clause influences complement choice, leading to a relatively higher proportion of finite complementation patterns by increasing the complexity of the syntactic environment. Studies have also shown that different types of negation, namely not- and no-negation, increase the tendency towards more explicit complementation options (Rohdenburg 2015). The current study focuses on the effect of not- and no-negation on the complementation profile of the verb regret, which allows variation between finite that/zero-complement clauses and nonfinite (S) -ing clauses. The GloWbE corpus was used to create a data set of more than 4,000 examples from 16 varieties of English. The results of the analysis support previous findings that the presence of a negative marker in the complement clause increases the preference for finite patterns, especially in L2 varieties of English. However, contrary to the expectations of this study, no-negation was found to have a stronger effect on complement choice than not-negation.
