Elements of Latin Lesson 39
The Present Infinitive and the Present Imperative, Active and Passive


Dum spīrō, spērō — While I breathe, I hope
Closing words of the motto of the state of South Carolina. Free translation, "While there's life, there's hope."

284. Infinitive Defined. The infinitive is a verbal noun, giving the general meaning of the verb without person or number; as, amāre, to love.

285. Present Infinitive. The present infinitive active is formed by adding -re to the present stem (154). The present infinitive passive may be formed from the active by changing final -e to , except in the third conjugation, which changes final -ere to .

audīre, to hear
vocā, to be called
monē, to be advised
regī, to be ruled
audī, to be heard

  a. The present infinitive of sum is esse. There is no passive.

286. Present Imperative. The active forms of the present imperative, already given in 249, are repeated below for comparison with passive forms. The present imperative passive ends in -re in the singular and in -minī in the plural. Thus the singular of the passive imperative is like the present active infinitive, and the plural is like the second person plural of the present indicative passive.
