Tense, Mood and Voice in Main Clauses

This page describes how the verb forms are used in independent clauses, the clauses that can stand alone as sentences. It covers the uses of the six tenses of the indicative, the commands (the imperative, the negative command and the jussive subjunctive), the other independent uses of the subjunctive (the wish, the possibility, the question of doubt and the concession), the main types of question, and the passive voice with its agent and its impersonal use. Subordinate clauses are left to the pages on Subordinate clauses, and the forms of the subjunctive are given in full on the page Subjunctive. The complete tables are in Paradigms: regular verbs.

Subjunctive forms needed here

The independent subjunctive appears so often in the sections below that the forms must be at hand. Only the active of amō and of sum is given here, and the full tables are on the page Subjunctive.

amō present amō imperfect amō perfect amō pluperfect
1 sg amem amārem amāverim amāvissem
2 sg amēs amārēs amāverīs amāvissēs
3 sg amet amāret amāverit amāvisset
1 pl amēmus amārēmus amāverīmus amāvissēmus
2 pl amētis amārētis amāverītis amāvissētis
3 pl ament amārent amāverint amāvissent
sum present sum imperfect sum perfect sum pluperfect
1 sg sim essem fuerim fuissem
2 sg sīs essēs fuerīs fuissēs
3 sg sit esset fuerit fuisset
1 pl sīmus essēmus fuerīmus fuissēmus
2 pl sītis essētis fuerītis fuissētis
3 pl sint essent fuerint fuissent

The present subjunctive of the other conjugations is moneat, regat, capiat and audiat in the 3rd singular. The perfect subjunctive resembles the future perfect indicative (amāverit, amāverint) in the 3rd person and differs in the 1st singular (amāverō) and in the long ī of the 2nd singular and the 1st and 2nd plural.

Tenses of the indicative

Tense Time Main uses Example, 3 sg of amō
Present now present action; habit and general truth; vivid narrative of the past amat he loves, he is loving
Imperfect past, continuing background, description, repeated or customary action, attempt amābat he was loving, used to love
Perfect past, completed simple past; present result amāvit he loved, he has loved
Pluperfect before a past time action completed before another past action amāverat he had loved
Future later what will happen amābit he will love
Future perfect completed before a future time action completed before another future action amāverit he will have loved

Present

  1. Present action: Iam diū tē exspectō. I have been waiting for you for a long time. (constructed) With iam diū, iam dūdum and similar words, Latin uses the present where English uses have been -ing.

  2. General truths and habit: Aqua ex nūbibus cadit. Rain falls from the clouds. (constructed)

  3. The historic present tells a past event as if it were happening, to make the narrative vivid: Caesar ad flūmen pervenit; pontem faciendum cūrat. Caesar reaches the river and has a bridge built. (constructed)

    Sīc itur ad astra.

    Thus one goes to the stars. (Vergil, Aeneid 9.641; the present of the impersonal passive, see below)

Imperfect

The imperfect describes a situation or an action in progress in the past. It supplies the background against which the perfect reports the events.

  1. Background and description:

    Conticuēre omnēs, intentīque ōra tenēbant.

    All fell silent and kept their faces intent. (Vergil, Aeneid 2.1; conticuēre is the perfect with the alternative ending -ēre, and tenēbant is the imperfect)

  2. Repeated or customary action: Cotīdiē in forum veniēbat. He used to come to the forum every day. (constructed)

  3. Attempted action (the conative imperfect): Hostēs castra expugnābant. The enemy were trying to storm the camp. (constructed)

  4. Letters. In letters the writer may use the imperfect or the perfect where English has the present, since the tense is that of the reader: Haec scrībēbam nocte. I am writing this at night. (constructed)

Perfect

The perfect has two functions, which English separates:

  1. The simple past (the aorist), which reports an event: he loved.

    Vēnī, vīdī, vīcī.

    I came, I saw, I conquered. (attributed to Caesar by Suetonius, Divus Iulius 37)

  2. The present perfect, which reports a past event as a present result: he has loved.

    Exēgī monumentum aere perennius.

    I have completed a monument more lasting than bronze. (Horace, Odes 3.30.1)

    Iacta alea est.

    The die has been cast. (Suetonius, Divus Iulius 32; a perfect passive)

    Some perfects mean, by their present result, that something has ended: vīxit he has lived (that is, he is dead), fuit it has been (that is, it is no more), dīxī I have spoken (I have finished).

  3. The gnomic perfect states a general truth as a fact of experience: Labor omnia vīcit improbus. Hard work has conquered everything. (Vergil, Georgics 1.145–146)

The perfect is also the tense that Latin uses after cum semel and similar words where English has has:

Nōbīs, cum semel occidit brevis lūx, nox est perpetua ūna dormienda.

For us, once the brief light has set, there is one endless night to sleep. (Catullus 5.5–6)

Pluperfect

The pluperfect marks an action that was completed before a past point:

Vīxī et quem dederat cursum Fortūna perēgī.

I have lived, and I have completed the course that Fortune had given. (Vergil, Aeneid 4.653; dederat is the pluperfect, vīxī and perēgī are present perfects)

Future and future perfect

The future and the future perfect are used more strictly than in English. A clause that refers to a future action takes the future or the future perfect even where English has the present:

Latin English
Sī vēneris, gaudēbō. If you come, I shall be glad. (constructed)
Cum domum redierō, tē vidēbō. When I return home, I shall see you. (constructed)
Ubi hoc fēcerō, quiēscam. When I have done this, I shall rest. (constructed)

The future perfect is used for an action that will be finished before another future action; English usually has a simple present or perfect: vēnerō I shall have come, once I have come.

Commands

Imperative

The positive command to one or several persons uses the imperative:

Singular Plural
amō amā amāte
moneō monē monēte
regō rege regite
capiō cape capite
audiō audī audīte
sum es este

Four verbs lose their final -e in the singular: dīc, dūc, fac and fer (plural dīcite, dūcite, facite, ferte). A future imperative in -tō (amātō) exists and is used in laws and in commands for later action.

Cavē canem.

Beware of the dog. (the mosaic warning in Petronius, Satyricon 29)

Negative commands

Latin does not use nōn with the imperative. A negative command to one or more persons has three forms:

Form Example Use
nōlī / nōlīte with the infinitive Nōlī timēre! the usual form in prose and speech
nē with the perfect subjunctive Nē timuerīs. a polite or solemn prohibition
nē with the imperative Nē timē! poetry and early Latin

Tū nē quaesierīs, scīre nefās.

Do not ask; it is forbidden to know. (Horace, Odes 1.11.1; nē quaesierīs is the perfect subjunctive in a prohibition)

Jussive subjunctive

The present subjunctive expresses a command, an exhortation or a demand where there is no imperative, that is, in the 1st person and in the 3rd person. The negative is nē.

Person Positive Negative
1st (plural) amēmus let us love nē amēmus let us not love
2nd amā (imperative) nōlī amāre, nē amāverīs
3rd amet let him love nē amet let him not love

The 1st person is also called the hortatory subjunctive.

Moriāmur et in media arma ruāmus.

Let us die and rush into the midst of the weapons. (Vergil, Aeneid 2.353)

Ōderint dum metuant.

Let them hate, provided that they fear. (a line of Accius quoted by Suetonius, Caligula 30; ōderint is the perfect subjunctive of the defective verb ōdī)

The 2nd person subjunctive can also be a mild command or advice, as when Catullus talks to himself:

Miser Catulle, dēsinās ineptīre, et quod vidēs perīsse perditum dūcās.

Poor Catullus, you should stop being foolish, and what you see has perished you should consider lost. (Catullus 8.1–2)

Wishes: the optative subjunctive

A wish is expressed by the subjunctive, with or without utinam (if only). The negative is nē or utinam nē. The tense shows whether the wish can still come true:

Wish about Tense Example (constructed) Translation
the future, possible present Utinam vīvat! May he live!
the present, unfulfilled imperfect Utinam adesset! If only he were here!
the past, unfulfilled pluperfect Utinam vēnisset! If only he had come!
negative nē or utinam nē Utinam nē vēnissem! If only I had not come!

A wish with the present subjunctive and no utinam is also common in formulas: Sit tibi terra levis. May the earth be light on you. (a stock epitaph formula), and Valeat! May he fare well! (constructed)

Possibility: the potential subjunctive

The subjunctive can state what may, might, could or would happen, without a condition expressed. The negative is nōn.

Time Tense Example (constructed) Translation
present or future present (or perfect) Dīcat aliquis. Someone may say.
present or future present Quis dubitet? Who would doubt?
past imperfect Vidērēs mīlitēs fugientēs. You would have seen soldiers fleeing.
polite statement present or imperfect Hoc velim. I should like this.

The 2nd person singular is often indefinite (one): crēdās one might believe, vidērēs one would have seen.

Quis cladem illīus noctis, quis fūnera fandō explicet aut possit lacrimīs aequāre labōrem?

Who could tell in words the slaughter of that night, who could match its suffering with tears? (Vergil, Aeneid 2.361–362)

The potential subjunctive is the independent form of the conclusion of a conditional sentence, which is treated on the page Conditionals.

Questions

Types of direct question

Type Marker Expects Example (constructed)
Question of fact -ne on the first word open Audīsne mē? Do you hear me?
nōnne the answer yes Nōnne mē audīs? Surely you hear me?
num the answer no Num mē audīs? You do not hear me, do you?
Word question quis, quid, cūr, ubi, quō, quandō information Cūr tacēs? Why are you silent?
Double question utrum ... an one of two Utrum domī manēs an abīs? Do you stay at home or are you going away?

A question without any marker is also possible, and the intonation or the context shows it. The indicative is the mood of the direct question of fact, and a question that asks what is to be done uses the subjunctive.

Deliberative subjunctive

The deliberative subjunctive asks what is to be done, or what could be done, and expresses doubt, perplexity or indignation. It is always a question, and the negative is nōn.

Time Tense Example (constructed) Translation
present or future present Quid faciam? What am I to do?
past imperfect Quid facerem? What was I to do?
present or future (1st plural) present Quō fugiāmus? Where are we to flee?

Quid igitur faciam? Nōn eam?

What am I to do, then? Am I not to go? (Terence, Eunuchus 46–49)

Exclamations

Exclamations are often in the accusative (Mē miserum! Poor me!, a stock expression). In the following line the case of the exclamation is disputed:

Ō tempora, ō mōrēs!

What times, what customs! (Cicero, First Catilinarian 1.2; grammarians disagree whether tempora and mōrēs are nominative or accusative of exclamation)

Concession

A concession grants a point for the sake of argument. The concessive subjunctive uses the present for a present concession and the perfect for a past one, and the negative is nē:

Example (constructed) Translation
Sit fūr; tamen homō est. Granted that he is a thief, he is still a man.
Fuerit vir bonus; nōn tamen sapiēns fuit. Granted that he was a good man, he was not wise.
Estō. Be it so. Granted.

estō is the future imperative of sum and is used in a concession. The concessive clauses with ut, cum, quamvis and etsī are subordinate clauses, treated on Subordinate clauses.

Passive voice

Passive and its agent

A transitive verb can be turned from the active to the passive: the object of the active becomes the subject of the passive, and the subject of the active becomes the agent.

Active Passive
Mīlitēs Caesarem laudant. The soldiers praise Caesar. Caesar ā mīlitibus laudātur. Caesar is praised by the soldiers.
  • A person as agent takes ā or ab with the ablative (ab before a vowel or h, ā before most consonants): ab hostibus caesī sunt they were cut down by the enemy. (constructed)

  • A thing as means or instrument takes the ablative alone: Mīlitēs gladiīs vulnerantur. The soldiers are wounded with swords. (constructed)

  • With the perfect passive participle and the gerundive, the agent is often in the dative (mihi, tibi); see Dative and the page Infinitive and participle constructions.

  • The agent is often omitted when it is unknown or unimportant:

    Gallia est omnis dīvīsa in partēs trēs.

    Gaul as a whole is divided into three parts. (Caesar, De Bello Gallico 1.1)

  • Some passive forms have a middle sense, in which the subject acts on itself: lavor I wash (myself), vertor I turn (myself).

  • A deponent has passive forms and an active meaning, and has no true passive (see Deponent and semi-deponent verbs).

Impersonal passive

An intransitive verb cannot have a personal passive, since there is no object to become the subject. It has an impersonal passive in the 3rd person singular (and the neuter in the perfect), which names the action without naming the actors:

Form Translation
ītur people go, there is a going (from eō)
pugnātur there is fighting, they fight
vīvitur one lives
ventum est they came, people came
itum est there was a going

Sīc itur ad astra.

Thus one goes to the stars. (Vergil, Aeneid 9.641)

Verbs that take the dative are also intransitive in Latin, and their passive is impersonal: Mihi nōn crēditur. I am not believed (literally it is not believed to me), Nōbīs persuāsum est. We have been persuaded. (both constructed) A personal passive such as ego persuādeor does not exist.

Parsing practice

Give the tense, mood and voice, the person and number, and the use.

  1. dēsinās (Catullus 8.1)
  2. vīvāmus
  3. nē quaesierīs
  4. nōlī timēre
  5. dederat

  11. possit (Vergil, Aeneid 2.362)
  12. vēnerō
  13. dīcat aliquis
  14. ab hostibus caesī sunt

Answers

  1. Present subjunctive active, 2nd singular of dēsinō: a mild command (jussive). You should stop.
  2. Present subjunctive active, 1st plural of vīvō: hortatory. Let us live.
  3. Perfect subjunctive active, 2nd singular of quaerō (the contracted form of quaesīverīs), with nē: prohibition. Do not ask.
  4. Imperative of nōlō with the infinitive: negative command. Do not be afraid.
  5. Pluperfect indicative active, 3rd singular of dō. He (she, it) had given.
  6. Perfect indicative active, 1st singular of exigō: present perfect. I have completed.
  7. Imperfect indicative active, 3rd plural of teneō: background action. They were holding.
  8. Present indicative passive, 3rd singular of eō: impersonal passive. One goes.
  9. Imperfect subjunctive active, 3rd singular of adsum: optative, an unfulfilled wish in the present. If only he were here.
  10. Present subjunctive active, 1st singular of faciō: deliberative. What am I to do?
  11. Present subjunctive active, 3rd singular of possum: potential. Who could ...
  12. Future perfect indicative active, 1st singular of veniō. I shall have come. (the perfect subjunctive is vēnerim)
  13. Present subjunctive active, 3rd singular of dīcō: potential. Someone may say.
  14. Perfect indicative passive, 3rd plural of caedō, with ab and the ablative of the agent. They were cut down by the enemy.

Common pitfalls

  • Translating the Latin perfect only as an English simple past. It can also be a present perfect: exēgī I have completed.
  • Treating the imperfect as a simple was. It describes a continuing, repeated or attempted action.
  • Using the present in a clause about the future. Latin has sī vēneris, not sī veniās, and cum redierō, not cum redeō.
  • Confusing the future perfect and the perfect subjunctive. vēneris (future perfect, short i) differs from vēnerīs (perfect subjunctive, long ī), and the 3rd person forms coincide.
  • Using nōn in a command, a wish or an exhortation. The negative is nē (or nōlī with the infinitive).
  • Using nē with the present subjunctive in a prohibition to the 2nd person. The usual forms are nōlī with the infinitive and nē with the perfect subjunctive.
  • Taking a deliberative subjunctive for a future. Quid faciam? is What am I to do?, not What shall I do? (though the difference is slight).
  • Translating a potential subjunctive as a future. Dīcat aliquis is someone may say; the future is dīcet aliquis.
  • Confusing amēmus (hortatory, long ē) with amāmus (indicative).
  • Forgetting the agent construction. A person takes ā or ab with the ablative, and a thing takes the ablative alone.
  • Making a personal passive of an intransitive verb or of a verb with the dative. Only the impersonal passive exists.
  • Forming a passive of a deponent. A deponent is active in meaning.

Self-test

  1. Which tense gives the background of a story, and which gives the events?
  2. Translate and explain the tenses: Sī vēneris, gaudēbō. Cum domum redierō, tē vidēbō.
  3. Give three ways to say Do not fear to one person.
  4. Translate: Vīvāmus. Nē moriāmur. Sit fēlīx. Utinam adesset. Utinam nē vēnissem.
  5. What does Quid faciam? mean, and what is the mood?
  6. What is the difference between dīcat aliquis and dīcet aliquis?
  7. Translate and explain the construction of the agent and the means: Caesar ā mīlitibus laudātur. Mīlitēs gladiīs vulnerantur.
  8. What does pugnātur mean, and why is it impersonal?
  9. Why can one not say ego persuādeor? What does Latin say instead?
  10. What is the difference between vīxit and vīvit?

Answers

  1. The imperfect gives the background and the perfect gives the events.
  2. If you come, I shall be glad. When I return home, I shall see you. Latin has the future perfect (vēneris, redierō) where English has the present.
  3. Nōlī timēre. Nē timuerīs. Nē timē. (the last is poetic).
  4. Let us live. Let us not die. May he be happy. If only he were here. If only I had not come.
  5. What am I to do? The mood is the subjunctive, used as a deliberative question.
  6. dīcat aliquis is a potential subjunctive (someone may say). dīcet aliquis is a future indicative (someone will say).
  7. Caesar is praised by the soldiers (agent, ā with the ablative); The soldiers are wounded with swords (means, ablative alone).
  8. There is fighting. pugnō is intransitive and has no object, so it forms only the impersonal passive in the 3rd singular.
  9. persuādeō takes the dative and is intransitive in Latin, so only the impersonal passive exists: mihi persuādētur, I am persuaded, or in the perfect mihi persuāsum est.
  10. vīxit is perfect (he lived, or he has lived, hence he is dead). vīvit is present (he lives).
