Future Active Infinitive
(Page 277)
In English there is no special form for the future active infinitive.
In Latin the future active infinitive is a combination of the future
active participle + esse. The future active participle is made up
of the participial stem + ur + us -a -um:
vocat + ur + us -a -um = vocaturus -a -um = about to call
The indicator for the future participle is -urvocaturus + esse = vocaturus esse = to be about to call

The Four Uses of the Infinitive
1. Complementary Infinitive
(English Word Order = Subject Verb Infinitive)
The man desires to work.
Vir laborare desiderat.
2. Subjective Infinitive
(Infinitive used as a subject or predicate nominative)
It is pleasant to walk.
Ambulare est gratum. or
Est gratum ambulare.
3. Objective Infinitive
(English Word Order = Subject Verb Noun/Pronoun Infinitive)
The farmer taught the slaves to work.
Agricola servos laborare docuit.
(The accusative noun servos in front of the infinitive is called a subject accusative.)

Indirect Statement (Indirect Discourse)
(Page 278)
In Latin when a simple statement is indirectly quoted, the verb is changed
from the indicative mood in the direct statement to the infinitive in the indirect
statement, and the subject is changed from the nominative to the accusative
case.
Direct statement:
Vir ambulat.
The man is walking.
Indirect statement:
Dicit virum ambulare.
He says that the man
is walking.
Difference between English and Latin Indirect Statement
English
Latin

The introductory word that is used.
The subject is in the nominative case.
The verb is in the infinitive.
There is no introductory word.
The subject is in accusative case.
Nota Bene:
(Page 278)
Indirect Statements usually follow verbs of mental action, such as
say, tell, know, think, hear, perceive, and the like.
These verbs should be memorized:
dico (3), say, tell
scio (4), know
puto (1), think
audio (4), hear
nego (1), say not, deny video (2), see
nuntio (1), announce, tell
sentio (4), feel, perceive
existimo (1), think
Sequence of Tenses for Indirect Statement
The present infinitive denotes the same time as the main verb;
The perfect infinitive denotes time before that of the main verb;
The future infinitive denotes time after that of the main verb.
