 Another ontological distinction that has been elucidated significantly using natural language is the distinction between objects and events. While some philosophers take objects and events to be of the same category and identify both with the material content of space-time regions, others distinguish them in the way they persist through time (endurance and perdurance, see entry on  identity over time).  Natural language gives significant support for the view that objects and events relate to time and space differently. The difference is reflected in the choice of existence predicates: exist applies to objects, but occur, take place, happen to events (* The palace existed / ??? happened, The murder happened / ??? existed)); it also reflected in the applicability of spatial modifiers to the respective existence predicates (The party took place in the garden, ??? The flowers existed in the garden) (Hacker 1982; Cresswell 1986; Fine 2006; Moltmann 2020b).
