The Welsh of Jesus and Job: Verb-second in Middle Welsh

Middle Welsh is a VSO language with the verb before the subject in all kinds of finite clause. However, positive declarative main clauses normally show verb-second order with a constituent of some kind before the finite verb. There are questions about the nature of this restriction. There are also questions about subject-initial sentences, which show surprising agreement properties, whether the subject is a topic or a focused constituent. All these questions can be given plausible answers within HPSG.
