Latin tenses

Latin tenses is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Latin tenses rather than just read about it. In short: The main Latin tenses can be divided into two groups: the present system (also known as infectum tenses), consisting of the present, future, and imperfect; and the perfect system (also known as perfectum tenses), consisting of the perfect, future perfect, and pluperfect. To these six main tenses can be added various periphrastic or compound tenses, such as ductūrus sum 'I am going to lead', or ductum habeō 'I have l…

Reference excerpt

The main Latin tenses can be divided into two groups: the present system (also known as infectum tenses), consisting of the present, future, and imperfect; and the perfect system (also known as perfectum tenses), consisting of the perfect, future perfect, and pluperfect. To these six main tenses can be added various periphrastic or compound tenses, such as ductūrus sum 'I am going to lead', or ductum habeō 'I have led'. However, these are less commonly used than the six basic tenses. In addition to the six main tenses of the indicative mood, there are four main tenses in the subjunctive mood and two in the imperative mood. Participles in Latin have three tenses (present, perfect, and future). The infinitive has two main tenses (present and perfect) as well as a number of periphrastic tenses used in reported speech. Latin tenses do not have exact English equivalents, so that often the same tense can be translated in different ways depending on its context: for example, dūcō can be translated as 'I lead', 'I am leading' or 'I led', and dūxī can be translated as 'I led' and 'I have led'. In some cases Latin makes a distinction which is not made in English: for example, imperfect eram and perfect fuī both mean 'I was' in English, but they differ in Latin.

Overview

The six main tenses

Active voice The six main indicative tenses in classical Latin are the following, using the verb dūcō as an example: (a) Infectum tenses

Present: dūcō 'I lead, I am leading' Future: dūcam 'I will lead, I will be leading' Imperfect: dūcēbam 'I was leading, I used to lead' (b) Perfectum tenses

Perfect: dūxī 'I led, I have led' Future Perfect: dūxerō 'I will have led' Pluperfect: dūxeram 'I had led' The three perfectum tenses are made using a different stem (in this case dūx- instead of dūc-). The perfect stem can usually not be guessed, and must be learnt from a dictionary.

Passive voice There are also indicative paradigms for all six tenses in the passive voice, as follows: (a) Infectum tenses

Present: dūcor 'I am led, I am being led' Future: dūcar 'I will be led, I will be being led' Imperfect: dūcēbar 'I was being led, I used to be led' (b) Perfectum tenses

Perfect: ductus sum (ductus fuī) 'I was led, I have been led' Future Perfect: ductus erō (ductus fuerō) 'I will have been led' Pluperfect: ductus eram (ductus fueram) 'I had been led' The perfectum system has simple tenses in the active (dūxī, dūxerō, dūxeram) and compound tenses in the passive (ductus sum, ductus erō, ductus eram). The periphrasis for the perfectum passive tenses is made of a passive perfect participle (ductus, ducta, ductum, ductī, ductae, ducta, which changes according to the gender and number of the subject) combined with different tenses of the verb sum 'I am'. The forms in brackets were rare in Classical Latin, but became more common in post-classical times. In some cases, during the classical period, a difference in meaning between the two forms can be discerned. The order of the words in a compound tense can be inverted, e.g. sum ductus etc. If the negative adverb nōn 'not' is added, various orders are possible, e.g. nōn est ausus, ausus nōn est, nōn ausus est 'he did not dare' (the first is the most common).

Deponent verbs Certain verbs in Latin have the form of a passive verb, but the meaning is active. These verbs are known as deponent verbs. An example is the verb sequor 'I follow': (a) Infectum tenses

Present: sequor 'I follow, I am following' Future: sequar 'I will follow, I will be following' Imperfect: sequēbar 'I was following, I used to follow' (b) Perfectum tenses

Perfect: secūtus sum (secūtus fuī) 'I followed, I have followed' Future Perfect: secūtus erō (secūtus fuerō) 'I will have followed' Pluperfect: secūtus eram (secūtus fueram) 'I had followed'

Periphrastic tenses The so called "periphrastic conjugation" is formed from the future participle (ductūrus, ductūra, ductūrum, etc., depending on the gender and number of the subject) combined with various tenses of the verb sum 'I am'. For example:

ductūrus sum 'I am going to lead, I am planning to lead' ductūrus erō 'I will be going to lead' ductūrus eram 'I was going to lead, I was planning to lead' ductūrus fuī 'I was going to lead' and so on. Examples are given below. A passive periphrastic conjugation can be made using a gerundive instead of a participle. This usually has a necessitative meaning such as 'need' or 'have to':

dūcendus sum 'I need to be led' dūcendus erō 'I will need to be led' dūcendus eram 'I needed to be led' and so on. The gerundive also changes according to the number and gender of the subject (dūcenda, dūcendum, dūcendī, dūcendae etc. A third type of periphrastic conjugation, which eventually developed into the perfect or pluperfect tenses in Romance languages such as Italian and French, is formed from the accusative perfect participle (ductum, ductam, ductōs etc., according to the gender and number of the object) combined with various tenses of habeō 'I have', for example:

ductum habeō 'I have led' ductum habēbō 'I will have led' ductum habēbam 'I had led'

Archaic forms Occasionally, especially in poetry, there occur archaic forms which don't conform to the usual patterns of tense formation. These include futures or future perfects with -s- such as iussō 'I will have ordered', faxō 'I will ensure'; subjunctives with -s- such as ausim 'I would dare', faxim 'I would do'; archaic subjunctives such as siem, fuam or duim; infinitives in -ier or -assere such as vituperarier or impetrāssere; shortened perfect or pluperfect forms such as dīxe (for dīxisse), ērēpsēmus (for ērēpsissēmus), vīxet (for vīxisset) etc. These are discussed below.

Indicative

Present

Formation The present tense of regular verbs is formed in different ways according to the conjugation of the verb.

1st conjugation: amō 'I love' (-ō, -ās, -at, -āmus, -ātis, -ant) 2nd conjugation: videō 'I see' (-eō, -ēs, -et, -ēmus, -ētis, -ent) 3rd conjugation (-ō): dūcō 'I lead' (-ō, -is, -it, -imus, -itis, -unt) 3rd conjugation (-iō): capiō 'I capture' (-iō, is, -it, -imus, -itis, -iunt) 4th conjugation: audiō 'I hear' (-iō, -īs, -it, -īmus, -ītis, -iunt) The six endings in brackets mean 'I, you (singular), he/she/it, we, you (plural), they' respectively. Thus amās means 'you (sg.) love', amat 'he/she/it loves' and so on. Irregular verbs:

Worked examples

Example 1 — a first encounter with Latin tenses

Start with the simplest possible case. Write down what Latin tenses claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Latin tenses before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Latin tenses ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Latin tenses

In research: Latin tenses appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Latin tenses in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Latin tenses is common in secondary-school and first-year university syllabi. It links to neighbouring topics Grammatical tenses, Indo-European verbs, Latin grammar, so understanding it makes those chapters shorter.
In everyday life: Look for Latin tenses outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
