	The presence of a SUBJ in the verb's f-structure is guaranteed by '''Completeness''': since the verb selects a SUBJ in its PRED value, there has to be a SUBJ. And that SUBJ has its own f-structure. Any feature-value pairs in the place of the dots inside the embedded brackets above must be present in the f-structure of the SUBJ. This is an example of feature government.

	Unfortunately, that does not capture all the possibilities of using non-third-person singular present tense verbs, since they can also be plural. So, we need a separate lexical entry for the plural ''disappear'':		Unfortunately, that does not capture all the possibilities of using non-third-person singular present tense verbs, since they can also be plural.

	We now need to ensure that only expressions with features like those of ''she'' can act as subjects of a verb like ''disappears''. This is easy to accomplish: in order for ''disappears'' to impose feature values on its SUBJ, it can simply refer to the f-structure of that SUBJ, as follows:		We now need to ensure that only expressions with features like those of ''she'' can act as subjects of a verb like ''disappears''.
