_213._ The Infinitive with Subject Accusative. The _infinitive_ (cf.
Sec. 173) is a _verbal noun_. Used as a noun, it has the constructions
of a noun. As a verb it can govern a case and be modified by an adverb.
The uses of the infinitive are much the same in Latin as in English.

1. In English certain verbs of _wishing, commanding, forbidding_, and
the like are used with an object clause consisting of a substantive in
the objective case and an infinitive, as, _he commanded the men to
flee_. Such object clauses are called infinitive clauses, and the
substantive is said to be the subject of the infinitive.

Similarly in Latin, some verbs of _wishing, commanding, forbidding_,
and the like are used with an object clause consisting of an
infinitive with a subject in the accusative case, as, /Is viros
fugere iussit\, _he commanded the men to flee_.

_214._ RULE. Subject of the Infinitive. _The subject of the infinitive
is in the accusative._

_215._ The Complementary Infinitive. In English a verb is often
followed by an infinitive to complete its meaning, as, _the Romans are
able to conquer the Gauls_. This is called the _complementary_
infinitive, as the predicate is not _complete_ without the added
infinitive.

Similarly in Latin, _verbs of incomplete predication_ are completed by
the infinitive. Among such verbs are /possum\, _I am able, I can_;
/propero\, /maturo\, _I hasten_; /tempto\, _I attempt_; as

Romani Gallos superare possunt,
_the Romans are able to_ (or _can_) _conquer the Gauls_
Bellum gerere maturant,
_they hasten to wage war_

_a._ A predicate adjective
