14.01.27: Level 2 (review); Carolus et Maria [38] (2)

[3] “Prīmō nihil respondī neque fēcī. Deinde, quod illī virī magnā vī vidēbantur et impetum eōrum timuī, cōnsilium celeriter cēpī. Hōc modō mēcum dīxī: ‘Nūlla arma habeō et nūllōs sociōs. Nihil conicere possum. Sīc mē dēfendere nōn possum. Salūtem in fugā petam. Paene exsul sum. At sī ego homō sapiēns sum, pecūniam meam rapī nōn sinam. Equī sōlī mē servābunt.’

[v] Why does he refer to the horses? (1)

[4] “Nunc latrōnēs in summō carrō stābant. Subitō equōs meōs incitāvī. Latrōnēs, quī id nōn exspectābant, nōn iam in carrō stāre poterant. Subitō in grāmine iacēbant. Tergum meum vertī et ē cōnspectū eōrum properāvī. Celeriter equī meī currēbant. Diū, autem, vōcēs latrōnum audīvī. Diū clāmōrēs eōrum mē perterrēbant. Pontem tūtō trānsieram. Etiam equī perīculum impetūs sentīre vidēbantur. Usque ad iānuam stabulī magnā vī cucurrērunt. Victōria mea erat grāta. Amīcī meī mē nōbilem fortemque putābant.”

____________________

Grammar note:

In this text and the previous one [37], the following two words occur:

• habitūrus, -a, -um: about to / going to have
• reditūrus, -a, -um: going to return

This construction is discussed in depth at Level 3. However, since it is used briefly in these texts, we’ll give a short explanation:

[1] The distinctive ending -ūrus, -ūra, -ūrum marks a future active participle and specifically indicates about to or going to or intending to do something.

[2] They decline like a 1^st / 2^nd declension adjective.

[3] They most commonly occur with the verb esse:

auxilium habitūrus erat | he was going to have help

agricolam mox reditūrum esse spērant | literally: (they) hope the farmer soon to be going to return = (they) hope that the farmer is going to return soon

25.09.25: Level 3; the grammar of things to come: diēs īrae (Requiem); the future active participle

https://adckl.blogspot.com/2025/06/250925-level-3-grammar-of-things-to.html

At this stage, simply be able to recognise the ending rather than exploring its uses too deeply.

Exercise [4]: Choose the correct translation [a] [b] or [c]

Note:

(1) Identify the tense of the verb which introduces the indirect statement e.g. he says / he said, because that will determine whether English translates the indirect statement as will or would

(2) Where pronouns are involved as the subject of the indirect statement, they will come first and, to double check, look at the ending of the future active infinitive. From the first question:

Horātia putāvit …

Is it: Horatia thinks … will … or Horatia thought … would …?

… tē puellam iūturum esse.

Who is doing the helping? Is it you [tē] or the girl [puellam]? Does iūturum agree with puellam?

02.02.26: Level 3; indirect statement; the accusative-infinitive [18]; future active infinitive

images #1 and #2: the future active infinitive is formed from the future active participle with ‘esse’ to express in an indirect statement what somebody is going to do; the future active participle will agree with the accusative subject of the indirect statement.

https://adckl.blogspot.com/2025/06/250925-level-3-grammar-of-things-to.html

laudō, -āre, -āvī, laudātus [perfect passive participle: having been praised]

> laudātūrus, -a, -um [future active participle: about to / going to praise]

> laudātūrus, -a, -um esse [future active infinitive to be about to /  going to praise]

portō, portāre, portāvī, portātus > portātūrus, -a, -um > ¦ portātūrus, -a, -um esse │ to be going to / about to carry

videō, vidēre, vīdī, vīsus > vīsūrus, -a, -um > ¦ vīsūrus, -a, -um esse │ to be going to see

pōnō, pōnere, posuī, positus > positūrus, -a, -um > ¦ positūrus, -a, -um esse │ to be going to put

audiō, audīre, audīvī, audītus > audītūrus, -a, -um > ¦ audītūrus, -a, -um esse │ to be going to listen

The future active infinitive agrees with the accusative case subject in gender and number.

Dīcit ¦ rēgem mīlitēs laudātūrum esse. │ He says that the king is going to praise the soldiers.

Dīcit ¦ rēginam mīlitēs laudātūram esse. │ He says that the queen is going to praise the soldiers.

Dīcit ¦ mīlitēs ducem laudātūrōs esse. │ He says that the soldiers are going to praise the commander.

Dīcit ¦ deās rēgīnam laudātūrās esse. │ He says that the goddesses are going to praise the queen.

[2] Remember the distinction in Latin when expressing he / she / they in indirect statements

[a] If the subject of the indirect statement is the same as the person who introduces it, then sē is used:

Rēx [masculine singular] dīcit ¦ sē mīlitēs laudātūrum [masculine accusative singular] esse. │ The king says that he [referring to himself] is going to praise the soldiers.

Rēgīna [feminine singular] dīcit ¦ sē mīlitēs laudātūram [feminine accusative singular] esse. │ The queen says that she [referring to herself] is going to praise the soldiers.

Mīlitēs [masculine plural] dīcunt ¦ sē ducem laudātūrōs [masculine accusative plural] esse. │ The soldiers say that they [referring to themselves] are going to praise the commander.

Deae dīcunt ¦ sē rēgīnam laudātūrās [feminine accusative plural] esse. │ The goddesses say that they [referring to themselves] are going to praise the queen.

[b] If the subject of the indirect sentence and the person who introduces it are not the same, then eum, eam, eōs, eās are used:

Rēgīna dīcit ¦ eum mīlitēs laudātūrum esse. │ The queen says that he is going to praise the soldiers.

Rēgina dīcit ¦ eam [e.g. deam] mīlitēs laudātūram esse. │ The queen says that she [referring to somebody else e.g. the goddess] is going to praise the soldiers.

Rēgina dīcit ¦ eōs [e.g. cīvēs] mīlitēs laudātūrōs esse. │ The queen says that they [e.g. the citizens] are going to praise the soldiers.

Rēgina dīcit ¦ eās [e.g. deās] mīlitēs laudātūrās esse. │ The queen says that they [e.g. the goddesses] are going to praise the soldiers.

i.e. the gender / number of the person who makes the statement is not involved, but the gender and number in the accusative of the subject of the indirect statement

[3] Where a verb has no perfect passive participle, it most often can be replaced by the supine, but the formation of the future active participle remains the same:

adveniō, advenīre, advēnī, supine adventum

> future active participle: adventūrus, -a, -um (about to arrive)

Dīcunt ¦ Plinium adventūrum esse │ They say that Pliny is about to / is going to / will arrive.

Dīxērunt ¦ Plinium adventūrum esse │ They said that Pliny was about to / was going to / would arrive.

[4]

[a] the future active infinitive of the verb esse itself is futūrus, -a, -um esse:

Longum hunc (morbum) futurum esse manifestum est (Celsus) │ It becomes evident that this (disease) is going to be / will be long (prolonged)

Lāvīnia locūta est sē uxōrem Aenēae futūram esse. │ Lavinia said that she would be the wife of Aeneas.

Tribūnī sē in auctōritāte patrum futūrōs esse pollicitī sunt (Livy) │ The tribunes promised that they would be under the authority of the Fathers. 

Ita Dāvum modo timēre sēnsī, ubi nūptiās futūrās esse audīvit (Terence) │ I felt that Davus was so afraid just now when he heard that there was going to be a marriage.

So alarmed did I perceive Davus to be just now, when he heard that there was going to be a marriage. 

… sē in tempore adfutūrum esse (Livy) │ (Hannibal said that) he would be there at the right moment.

[b] There is an alternative future active participle of sum: fore

vīdit in magnō sē fore perīculō (Nepos) │ He saw that he was going to be in great danger.

magnō sibī ūsuī fore arbitrābātur (Caesar) │ He thought that it would be very useful to him.

comitia fore nōn arbitror (Cicero) │ I do not think there will be an election.

in litterīs scrībit sē cum legiōnibus profectum celeriter adfore (Caesar) │ In the letter he wrote that he had set out with the legions and would soon be there

From Calgacus’ speech in Agricola by Tacitus:

Magnus mihi animus est ¦ hodiernum diem cōnsēnsumque vestrum initium lībertātis tōtī Britanniae fore

I have a sure confidence ¦ that this day, and this union of yours, will be the beginning of freedom to the whole of Britain.

Note: fore occurs in another construction which is related to this topic but will be discussed later in conjunction with the subjunctive.

[5] Note, once again, that, while English changes the tense of the indirect statement depending on the tense of the introductory statement e.g. they say that they will / are going to … / they said that he would / was going to …, Latin does not change the infinitive form.

Pater dīcit fīliōs crās locūtūrōs esse. │ The father says that the sons will speak tomorrow.

Graecī dīxērunt sē excessūrōs esse. │ The Greeks said that they would leave.

Didō  nūntiat sē moritūram esse. │ Dido announces that she is going to die.

Didō [feminine singular] nūntiāvit sē moritūram esse. │ Dido announced that she was going to / would die.

25.09.25: Level 3; the grammar of things to come: diēs īrae (Requiem); the future active participle

I suspect that Verdi just manages to snatch the gold medal from Mozart on this one:

[i] Mozart: with Latin text (Chapelle Royale)

https://www.youtube.com/watch?v=RKJur8wpfYM

[ii] Verdi: with English subtitles (Metropolitan Opera)

https://www.youtube.com/watch?v=X6cogix3cwQ

Diēs īræ, diēs illa │ The day of wrath, that day,
Solvet sæclum in favīllā │ will dissolve the world in ashes
Teste Dāvīd cum Sibyllā │ by the testimony of David together with the Sibyl.

Quantus tremor est futūrus │ How great is the quaking going to be
Quandō iūdex est ventūrus │ when the Judge is about to come,
Cūncta strictē discussūrus │ intending to investigate all things strictly

Vocabulary

favilla, -ae [1/f]: (hot / glowing) ashes

Sybilla, -ae [1/f]: sybil; referring to a number of Mediterranean prophetesses and, in particular, to the Cumaean sybil: https://en.wikipedia.org/wiki/Cumaean_Sibyl

saeclum, -ī [2/n] = saeculum, -ī [2/n]: (here) the world; worldliness

testis, -is [3m/f]: witness

Grammar: future active participle

We’re focussing on the words in bold ending in: -ūrus

This is a future active participle, translating as something is about to or going to happen or somebody is intending to do something. Some translations will give a simple future tense but the future active participle usually implies near future which, of course, the diēs īrae itself dramatically conveys.

The future active participle has the same endings and agrees and declines in the same way as any other 1^st / 2^nd declension adjective: -ūrus, -ūra, -ūrum

It is formed from the 4^th principal part of the verb i.e. either the perfect passive participle or the supine:

portō, portāre, portāvī, portātus

-ūr- is inserted before the -us (-a, -um) ending

> portāt¦ūr¦us, -a, -um: about to carry

discutiō, discutīre, discussī, discussus: (Late / Mediaeval meaning) examine

> discussūrus, -a, -um: about to examine

If a supine is listed (either because the verb has no perfect passive participle or the dictionary simply uses the supine as the standard way of indicating the 4^th principal part), it makes no difference: change the -um to -us and insert -ūr- before the ending:

veniō, venīre, vēnī, (supine) ventum

> ventūrus, -a, -um: about to come

The verb sum, esse has neither a perfect passive participle, nor a supine, and so it is the future active participle that is listed as the 4^th principal part:

sum, esse, fuī, (future active participle) futūrus, -a, -um: about to be (going to be / intending to be)

The ending -ūrus is very obvious when reading the language, and is easy to remember since it is in the English derivative future.

The future active participle is most commonly found with different tenses of sum, esse to state that somebody is, was or will be going to do something.

Quantus tremor est futūrus │ How great is the quaking going to be

Quandō iūdex est ventūrus │ when the Judge is about to come,

Cūncta strictē discussūrus │ (and is / who is) going to investigate all things strictly

Present: mansūrus sum: I am going to stay

Imperfect: mansūrus eram: I was going to stay

Future: mansūrus erō: I shall be going to stay; it can sound a little clumsy although, in spoken English, we would use it in a contracted form e.g. “I’ll be going to see him later”. However, when translating, we could equally convey the idea with a present progressive ‘I’m going to…’ since the English present progressive can convey both a present and a future concept. 

In general, translations such as “I (was) intend(ing) to…”, “I (was) mean(ing) to …” and other similar phrases can convey the future active construction.

Periphrastic constructions

This construction with sum, esse is known as periphrastic, a term which does come up in grammar books and refers to a verb form which requires more than one word to express the idea.

Compare:

habitābam = English: I used to live; English requires more than one word to express that idea i.e. it is periphrastic. The Latin, however, is not periphrastic since it only uses a single word.

Similarly:

habitābō = English: I shall live; again, the English construction is periphrastic whereas the Latin is not.

You have already seen periphrastic constructions although they have not been defined as such:

laudātus sum / eram / erō: I was (have been) / had been / will have been praised; those passive constructions in Latin are periphrastic since they use two words to convey the idea.

Below are examples using the future active participle with different tenses of sum, esse. Most of them are from Cicero’s letters; I have indicated those that are not. I have translated some of them very literally in order for the precise meaning of the future active participle to be clear.

Present

Astūtē nihil sum āctūrus. │ I am not going to act cunningly

… praeter ūnum L. Sullam, quem imitātūrus nōn sum │ … apart from L. Sulla, whose example I do not intend to follow [= literally: whom I am not going to imitate]

Quid tū igitur sēnsūrus es? │ What then will your view be? [ = are you going to feel]

"Quid ergō," inquis, "factūrus es”?│”What, therefore,” you say “are you going to do?”

Tū, sī ūnō in locō es futūrus, crēbrās ā nōbīs litterās exspectā │ Expect frequent letters from me, if you are settled [ = if you are going to be in one place]

etiamsī reditūrus ille est │ even if he is going to return

Cōnsulēs praesidia omnia dēductūrī sunt aut in Siciliam itūrī. │ The consuls are going to bring in all their garrisons or (will) go into Sicily.

Lūdī enim Antī futūrī sunt │ For there are going to be games at Antium

Imperfect

epistula, quam dē nocte datūrus eram │ the letter which I was going to dispatch last night

nec rogātūrus eram │ nor was I going to ask

Sī domum tuam expugnātūrus, captā domō dominum interfectūrus eram … (Livy)

If I had been going to attack your house, and the house having been captured, (been going to) kill the owner …

persecūtūrus erat Gnaeum │ he meant to [was going to] pursue Pompey

Arma quae ad mē missūrī erātis │ The arms which you were going to send to me

Future

illō ipsō diē, quō ad Siccam ventūrus erō │ on the very day that I will be going to arrive at Sicca’s place [very literal: a neater English would, of course, be “on the very day that I’m going to arrive” but the Latin does show the future active participle with the future of sum]

Mergite mē, flūctūs, cum reditūrus erō. (Martial) │ Drown me, waves, when I’m returning home [ = literally:  I shall be going to return]

… nē quem exercitum, quī cum populō Rōmānō sociīsve bellum gestūrus erit, rēx per fīnēs rēgnī suī eōrumve (Livy) │ … no army which shall purpose to wage war with the Roman people or its allies …

sī in urbem versus ventūrī erunt, mihi scrībēs (Trajan to Pliny) │ if they are going to return to Rome [ = literally: will be going to come …], you will write to me.
