On pseudo-non-finite clauses in Welsh

Languages differ in how they employ finite and non-finite clauses. Welsh finite and non-finite clauses have a similar distribution to their counterparts in English. However, it doesn’t look like this because Welsh has certain finite clauses which look rather like non-finite clauses. We examine two types of pseudo-non-finite clauses: finite "bod" clauses and finite "i" clauses. We argue that both cases are instances of a mismatch between syntax and morphology, while the latter only involves periphrasis. We provide an HPSG analysis capturing similarities and differences between these two constructions and canonical finite and nonfinite clauses.
