This chapter revisits my earlier work on to-infinitives (Los 1999, 2005) in the light of the new insights about the spread of complementation patterns provided by De Smet (2013) and Rudanko (2015). Their investigations into the spread of the gerund as a verb complement benefited from the fact that the gerund came into existence relatively recently, which made it possible not only to construct a scenario of how it spread through the system of verbal complementation, but also to date the various stages.
