Re: On the usage of the article "the" in Activity Vocabulary

exactly one actor and exactly one object?

No, as these properties are not defined as “functional” (having at most
exactly one value).

In English, “the” does not always represent a singular instance of
something, but rather sometimes the general class of that thing. For
example, a wildlife documentary might refer to “the majestic lion” without
necessarily talking about one specific lion.

In the descriptions given in the vocabulary, the use of “the” does not (and
should not be taken as to) imply that a property is restricted to one value.
