Infinitives and Indirect Statement in Latin

The Latin infinitive and the accusative-plus-infinitive construction used to report what someone says, thinks or knows.

One of Latin's most distinctive constructions is indirect statement, used to report what someone says, thinks or knows. It uses the accusative and the infinitive, which feels odd at first but is very regular.

The infinitive

The second principal part is the present infinitive:

Verb Infinitive Meaning
amō amāre to love
videō vidēre to see
regō regere to rule
audiō audīre to hear
sum esse to be

The infinitive also follows verbs like possum, volō (I want) and dēbeō (I ought):

  • Volō tē vidēre. — I want to see you.

Indirect statement

In English we say "He says that the girl is coming". In Latin, the subject of the reported statement goes into the accusative, and the verb becomes an infinitive:

  • Dīcit puellam venīre. — He says that the girl is coming.
  • Sciō tē bonum esse. — I know that you are good.
  • Putō Rōmam magnam esse. — I think that Rome is great.

There is no word for "that". The accusative subject and the infinitive do the work.

Tense of the infinitive

The tense of the infinitive is relative to the main verb:

Infinitive Meaning Example
present at the same time Dīcit puellam venīre. — He says the girl is coming.
perfect earlier Dīcit puellam vēnisse. — He says the girl came.
future later Dīcit puellam ventūram esse. — He says the girl will come.

The perfect infinitive is formed from the perfect stem plus -isse: amāvisse, vēnisse.

Verbs that introduce indirect statements

  • dīcō — I say
  • putō — I think
  • sciō — I know
  • audiō — I hear

Reading tip

When you see a verb of saying or thinking followed by an accusative noun and an infinitive, translate as "that ... is/does":

Puellam vēnisse audiō. — I hear that the girl has come.

Tips

  1. Look for an accusative plus infinitive.
