The long-term diachrony of referential null subjects in early English
Chapter 6 investigates the long-term diachrony of null subjects in early English. On the basis of a large-scale empirical analysis of overt and null referential subjects in Old, Middle, and Early Modern English, it is argued that no real diachronic decline in the possibility of null subjects can be detected across a period spanning c.850 years of early English texts. It is argued that this is consonant with a story where Old English does not feature a productive pro-drop property. The chapter also shows that verb-initial clausal syntax and conjunct clause environments constitute the strongest favouring effects for null subjects in Middle and Early Modern English, as is also the case in Old English. An argument is made that this is consonant with a story where subject omission in early English is viewed as a form of argument ellipsis.
