The conjunction aut means "or" in Latin and is one of the most essential words for forming questions and presenting alternatives in conversation. Unlike English which uses "or" for all types of alternatives, Latin distinguishes between exclusive alternatives (aut...aut = either...or) and inclusive alternatives (vel = or, in the sense of "possibly both"). In this lesson, we'll focus on aut and its conversational uses.
Definition: aut is a coordinating conjunction that presents mutually exclusive alternatives, similar to "either...or" in English.
Question: What does "aut" mean in Latin? Answer: "Aut" means "or" in Latin, specifically used for exclusive alternatives where only one option can be true or chosen.
In this lesson, aut will appear in various positions within sentences, showing its flexibility in Latin word order. You'll encounter it in questions, statements, and reported speech, reflecting how Romans actually used it in daily conversation.

Aut is a coordinating conjunction that connects words, phrases, or clauses of equal grammatical importance. Here are the essential rules: -
Basic Usage: Aut presents exclusive alternatives - only one option can be true or chosen. -
Example: Vīnum aut aquam (wine or water - not both) -
Doubled Construction: Aut...aut emphasizes the exclusivity of the choice. -
Example: Aut Caesar aut Pompēius (Either Caesar or Pompey) -
Word Order: Unlike English, aut can appear in various positions: -
Between alternatives: hodiē aut crās (today or tomorrow) -
At the beginning for emphasis: Aut studē aut discēde! (Either study or leave!) -
With Questions: -
Direct questions: Tū mē amās aut nōn? (Do you love me or not?) -
Indirect questions: Scīsne vīvit aut mortuus est? (Do you know whether he's alive or dead?) -
In Reported Speech: When reporting alternatives, use infinitive constructions: -
Dīcit sē aut manēre aut abīre velle (He says he wants either to stay or to leave)
-
Confusing aut with vel: -
Aut = exclusive (either/or, not both) -
Vel = inclusive (or, possibly both) -
Wrong: Pānem vel vīnum vīs? (if you mean to offer only one) -
Right: Pānem aut vīnum vīs? (Do you want bread or wine?) -
Forgetting to repeat aut for emphasis: -
Weak: Caesar aut Pompēius vincet -
Strong: Aut Caesar aut Pompēius vincet -
Word order in questions: English speakers often place aut too late: -
Awkward: Amāsne mē aut nōn? -
Natural: Tū mē amās aut nōn?
English uses "or" for both exclusive and inclusive alternatives, while Latin distinguishes: -
English: "Would you like tea or coffee?" (ambiguous) -
Latin: Theam aut coffēam vīs? (exclusive - one or the other) -
Latin: Theam vel coffēam vīs? (inclusive - one, the other, or both)
-
Identify the type of choice: Is it exclusive (only one option) or inclusive (possibly both)? -
Choose the conjunction: Use aut for exclusive, vel for inclusive -
Consider emphasis: Use aut...aut for strong either/or statements -
Place appropriately: -
Simple alternatives: place between them -
Emphatic statements: begin with aut -
Questions: often end with aut nōn?
-
Type: Coordinating conjunction -
Meaning: or (exclusive) -
Doubled form: aut...aut (either...or) -
Connects: Words, phrases, or clauses of equal rank -
Common phrases: -
aut...aut (either...or) -
aut nōn (or not) -
utrum...aut (whether...or)

For English speakers learning conversational Latin, understanding aut reveals important aspects of Roman thinking and communication:
Romans valued precise communication, especially in legal and philosophical contexts. The distinction between aut (exclusive) and vel (inclusive) reflects this precision. In the Senate, when proposing alternatives, speakers would carefully choose aut to make clear that only one option was possible.
The doubled construction aut...aut was a favorite rhetorical device. Cicero frequently used it in his speeches to present stark choices to his audience. This construction forces listeners to choose sides - there's no middle ground.
In markets and taverns, aut appeared in practical questions: -
Pānem aut carnem emis? (Are you buying bread or meat?) -
Hodiē aut crās? (Today or tomorrow?)
These weren't philosophical choices but practical decisions that shaped daily Roman life.
Roman teachers used aut to test students' understanding: -
Graecē aut Latīnē respondē! (Answer in Greek or Latin!) This forced students to demonstrate competence in one language or the other.
For modern Latin speakers, aut remains essential for: -
Academic discussions requiring precise alternatives -
Neo-Latin compositions where clarity is paramount -
Understanding classical texts where choices drive narratives
The Roman attention to exclusive versus inclusive "or" can help English speakers become more precise in their own language use, distinguishing between "Would you like tea or coffee?" (probably exclusive) and "Bring pens or pencils" (probably inclusive).

From Erasmus, Colloquia Familiaria (Convivium Religiosum):
Part F-A (Interleaved Text)
Eusebius Eusebius inquit says : " Placetne does it please vōbīs you all aut either in in hōc this viridiāriō garden aut or in in illā that porticu colonnade prandēre to lunch ?" ? Theophilus Theophilus respondet replies : " Utrōque in both locō place iūcundum pleasant erit it will be sed but tū you aut either hunc this aut or illum that locum place ēlige choose ."
Eusebius inquit: "Placetne vōbīs aut in hōc viridiāriō aut in illā porticu prandēre?" Theophilus respondet: "Utrōque locō iūcundum erit, sed tū aut hunc aut illum locum ēlige."
Eusebius says: "Would you like to lunch either in this garden or in that colonnade?" Theophilus replies: "It will be pleasant in either place, but you choose either this or that location."
Erasmus demonstrates the conversational use of aut in this dining dialogue. Notice how: -
Eusebius uses aut...aut to present two exclusive dining locations -
Theophilus cleverly acknowledges both options would be pleasant but insists on a single choice -
The repetition of aut in Theophilus's response emphasizes that only one location can be selected
-
Placetne: Impersonal verb with dative (vōbīs) -
aut in hōc viridiāriō aut in illā porticu: Parallel prepositional phrases connected by aut...aut -
Utrōque locō: Ablative of place, showing both options considered together -
tū...ēlige: Emphatic pronoun with imperative, putting the choice back on Eusebius -
aut hunc aut illum locum: Direct objects with demonstratives, maintaining the exclusive choice
This passage perfectly illustrates how aut functions in polite conversation - presenting clear alternatives while maintaining social grace.

This dialogue presents a master and students discussing wisdom, learning, and choice. The repeated structure with aut...aut (either...or) creates a pedagogical framework.
24.16-24.18: Opening question about wisdom vs. riches - Student 1 hesitantly chooses wisdom - Master questions the hesitation
24.19-24.20: Overcoming fear and shame - Student 2 admits confusion/fear - Master encourages boldness
24.21-24.22: The necessity of learning - Student 3: we must either learn or perish - Master asks about pace of learning
24.23-24.24: The choice to stay or leave - Students demand action or dismissal - Master: remaining will determine wisdom or foolishness upon departure
24.25-24.26: Extremes of determination - Student 1 vows victory or death through trying - Master calls this either best or worst counsel
24.27-24.30: From philosophy to action - Student 2 offers choice of topics - Master asks about reading the classics - Student admits having read neither but will begin - Master's final ultimatum: Begin now or never be wise
The aut...aut structure forces binary choices, reflecting: - Socratic method (questioning) - Stoic ethics (duty and choice) - Roman pragmatism (action over contemplation)
The dialogue culminates in urgent exhortation: wisdom demands immediate action (nunc), not procrastination (numquam).
24.16 Magister: "Quid māius est, aut sapientia aut dīvitiāe?" Teacher: "What is greater, wisdom or riches?"
24.17 Discipulus prīmus: "Aut errō aut sapientia melior est." First student: "Either I'm mistaken or wisdom is better."
24.18 Magister: "Cūr aut hesitās aut dubitās?" Teacher: "Why do you either hesitate or doubt?"
24.19 Discipulus secundus: "Aut nōn intellegō aut timidus sum." Second student: "Either I don't understand or I'm afraid."
24.20 Magister: "Nōlī aut timēre aut pudōrem sentīre!" Teacher: "Don't either fear or feel ashamed!"
24.21 Discipulus tertius: "Putō nōs aut dīscere aut perīre dēbēre." Third student: "I think we must either learn or perish."
24.22 Magister: "Vērum dīcis, sed aut citō aut tardē dīscitis?" Teacher: "You speak truly, but do you learn either quickly or slowly?"
24.23 Omnēs discipulī: "Aut doce nōs aut domum mittē!" All students: "Either teach us or send us home!"
24.24 Magister: "Manēbitis et aut sapientēs aut stultī discēdētis." Teacher: "You'll stay and leave either wise or foolish."
24.25 Discipulus prīmus: "Aut vīncam aut moriar temptandō!" First student: "I'll either succeed or die trying!"
24.26 Magister: "Hoc aut optimum aut pessimum cōnsilium est." Teacher: "This is either the best or worst plan."
24.27 Discipulus secundus: "Interrogā mē aut dē philosophiā aut dē mathēmaticā!" Second student: "Question me either about philosophy or about mathematics!"
24.28 Magister: "Aut Platōnem aut Aristotelem legistī?" Teacher: "Have you read either Plato or Aristotle?"
24.29 Discipulus: "Neutrōs, sed aut hodiē aut crās incipiam." Student: "Neither, but I'll begin either today or tomorrow."
24.30 Magister: "Aut nunc incipe aut numquam sapiēns eris!" Teacher: "Either begin now or you'll never be wise!"
24.16 Magister: "Quid māius est, aut sapientia aut dīvitiāe?"
24.17 Discipulus prīmus: "Aut errō aut sapientia melior est."
24.18 Magister: "Cūr aut hesitās aut dubitās?"
24.19 Discipulus secundus: "Aut nōn intellegō aut timidus sum."
24.20 Magister: "Nōlī aut timēre aut pudōrem sentīre!"
24.21 Discipulus tertius: "Putō nōs aut dīscere aut perīre dēbēre."
24.22 Magister: "Vērum dīcis, sed aut citō aut tardē dīscitis?"
24.23 Omnēs discipulī: "Aut doce nōs aut domum mittē!"
24.24 Magister: "Manēbitis et aut sapientēs aut stultī discēdētis."
24.25 Discipulus prīmus: "Aut vīncam aut moriar temptandō!"
24.26 Magister: "Hoc aut optimum aut pessimum cōnsilium est."
24.27 Discipulus secundus: "Interrogā mē aut dē philosophiā aut dē mathēmaticā!"
24.28 Magister: "Aut Platōnem aut Aristotelem legistī?"
24.29 Discipulus: "Neutrōs, sed aut hodiē aut crās incipiam."
24.30 Magister: "Aut nunc incipe aut numquam sapiēns eris!"
This scholastic dialogue showcases advanced uses of aut in academic discourse: -
Philosophical Alternatives: The dialogue opens with abstract choices (sapientia aut dīvitiāe), typical of scholastic debates where students must choose between competing values. -
Self-Reflective Statements: Students use aut...aut to express uncertainty about their own mental states (Aut errō aut sapientia melior est), showing the conjunction's use in internal deliberation. -
Imperatives with Alternatives: The teacher and students use aut with imperatives to create ultimatums (Aut doce nōs aut domum mittē!), a common pattern in academic settings. -
Temporal Alternatives: The conjunction connects time expressions (aut hodiē aut crās), showing how Romans conceptualized scheduling choices. -
Modal Expressions: Combined with verbs of obligation (dēbēre) and future tenses, aut expresses necessary choices about actions and outcomes. -
Rhetorical Escalation: The dialogue builds from simple choices to dramatic declarations (Aut vīncam aut moriar temptandō!), demonstrating how aut can create rhetorical intensity. -
Negative Responses: The use of neutrōs (neither) shows how to reject both alternatives presented with aut...aut. -
Academic Subject Choices: References to specific philosophers and subjects (aut dē philosophiā aut dē mathēmaticā) reflect real scholastic practice where students specialized in particular areas.
