necessitate

1. (transitive) To make necessary; to behove; to require (something) to be brought about.Examples: "The early departure of her plane necessitated her waking up at 4 a.m."; "And this to be a duty, […] ſpeciall that of loving God with all thy heart, &c. beſides manifold more in Scripture; But even the Law of Nature neceſſitates to it, whether we conſider God, or our ſelves, our ſoules, ſpecially."; "[T]here is a twofold Neceſſitie, one contrary to Libertie, another conſiſtent therewith. Wherefore externe Neceſſitie deſtroyes Libertie (for no one externally compelled, is ſaid to do, or not to do any thing freely) but al interne Neceſſitie neceſſitating to act according to their own nature, this doth the more preſerve Libertie."transitive

2. (of circumstances) To force into a certain course of action; compel.Examples: "The 26th of August was still colder than the day previous. Ice formed in all our water-vessels, and one was necessitated to the brisker kind of exercise in order to keep warm."
