An alternative question asks the listener to choose between stated possibilities: “Are you staying or leaving?” Classical Latin most explicitly frames that choice with utrum ... an ..., but it can also mark the first alternative with enclitic -ne or leave it unmarked. The second alternative is introduced by an, not normally by the ordinary coordinating conjunctions aut or vel.
This structure differs from a yes–no question. The expected answer is one of the alternatives, not simply ita or nōn. The particles map the architecture of the choice, while case, tense, and mood continue to come from the clauses themselves.
The three productive frames
Classical Latin has three common ways to introduce the first alternative. All converge on an before the second.
| Frame | Model | Register and nuance |
|---|---|---|
| utrum A an B? | Utrum manēs an abīs? | fully explicit; common in careful prose (neutral/formal) |
| A-ne an B? | Manēsne an abīs? | compact and common; first member overtly interrogative |
| A an B? | Manēs an abīs? | particle omitted in first member; natural when the choice is clear |
Utrum manēre an abīre māvīs?
Which do you prefer, to stay or to leave?
Venīsne nōbīscum an domī manēs?
Are you coming with us, or are you staying at home?
In the first question, utrum announces a choice before either infinitive appears. In the second, -ne attaches to venīs and an opens the competing clause. English uses “or” for both coordination and questions; Latin an specifically signals the second branch of an interrogative choice.
What utrum is doing
Interrogative-particle utrum is indeclinable and does not itself mean the first alternative. It announces that the proposition will be resolved by a contrast later introduced with an. English often translates it only through word order and “or”; there may be no separate English word corresponding to it.
Do not confuse this particle with neuter singular utrum of the declining interrogative uter, utra, utrum “which of two?” The forms are identical, but syntax separates them.
| Latin | Analysis | Translation |
|---|---|---|
| Utrum veniēs an manēbis? | indeclinable particle opening two clauses | Will you come or stay? |
| Utrum dōnum accipis? | neuter accusative adjective agreeing with dōnum | Which of the two gifts are you accepting? |
The second sentence needs context that supplies two gifts; there is no following an because utrum modifies dōnum, and the whole noun phrase fills the object slot. A quick diagnostic is substitution: if “which of the two?” fills or modifies a participant in the clause, the form declines; if it merely signals that A will be contrasted with B, it is the particle.
The size and scope of the alternatives
The alternatives can be single words, phrases, infinitives, or full clauses. They should answer the same underlying question and normally have parallel grammatical status.
| Alternative type | Example |
|---|---|
| nouns | Caeciliam an Lūciam exspectās? Are you waiting for Caecilia or Lucia? |
| destinations | Rōmamne an Neāpolim ībit? Will he go to Rome or Naples? |
| infinitives | Utrum tacēre an respondēre dēbēmus? Ought we to remain silent or answer? |
| clauses | Utrum frāter aderit an sōlus veniēs? Will your brother be there, or will you come alone? |
Rōmam an Athēnās aestāte proficīscimur?
Are we setting out for Rome or Athens in the summer?
Here neither alternative carries a particle of its own; an is the sole overt boundary. The accusatives Rōmam and Athēnās both express destination. Parallel form lets the listener recognize the choice immediately.
Word order may highlight the decisive contrast. Rōmamne an Athēnās ībit? focuses destinations; ībitne Rōmam an domī manēbit? contrasts whole courses of action. The enclitic attaches to the first focused word of the first member, not automatically to the final verb of the entire question.
“Or not”: an nōn and necne
When the second alternative is simply the denial of the first, direct Classical questions commonly use an nōn: veniēsne an nōn? “will you come or not?” The nōn negates the understood repeated verb. The fused-looking sequence is not a second expected-answer particle; an opens the alternative, and nōn supplies its negative content.
In indirect questions, necne is frequent for “or not”: quaerit utrum veniās necne “she asks whether you are coming or not.” Direct necne exists in some authors and periods, but an nōn is the safer productive Classical choice for direct composition. The distinction is one of distribution and register, not an absolute ban preserved uniformly throughout Latin history.
Mood and the kind of choice
Factual alternatives normally use the indicative. A subjunctive appears when the alternatives are deliberative or potential, not because utrum or an governs that mood.
| Question | Why that mood? |
|---|---|
| Utrum venit an domī manet? | indicative: asks what is actually happening |
| Eām an maneam? | subjunctive: deliberates over what I should do |
| Utrum hoc crēdāmus an reiciāmus? | subjunctive: deliberates over whether we should believe or reject it |
In an indirect alternative question, the verbs normally become subjunctive under the rule for reported questions: nesciō utrum veniat an maneat “I do not know whether he is coming or staying.” That is not the same as a direct deliberative. The related question particles in indirect questions page treats tense sequence and embedding in detail.
Answers and presupposition
An alternative question presupposes that the offered options are relevant. A bare ita “yes” may fail to identify which option the speaker accepts. Repeat the selected word or verb instead: to manēsne an abīs?, answer maneō or abeō. If the alternatives are not exhaustive, Latin can add another answer, but that rejects the framing rather than supplying an ordinary yes or no.
An can also introduce an alternative whose first half is understood from the preceding discourse: an tū aliter putās? “Or do you think otherwise?” This is common in argument (formal; rhetorical) and lively dialogue (informal; literary evidence). It does not make an a general substitute for aut. The missing first alternative must be recoverable from context.
An authentic poetic alternative and later continuity
Vergil supplies a compact direct alternative in Aeneid 3.39, preserved here source-faithfully:
eloquar, an sileam?
Should I speak out, or be silent?
The first alternative has no overt question particle; an alone marks the boundary before the second. Both verbs are deliberative subjunctives, so Aeneas is weighing what he should do, not asking which event is factually occurring. The lowercase spelling and absence of pedagogical macrons follow the cited edition rather than being silently normalized. This compressed zero ... an frame is especially effective in poetry (literary), although it is not restricted to verse.
Later prose, Christian Latin, and medieval Latin continue all three frames, though individual authors distribute utrum, an, aut, and necne differently. For Classical production, the explicit utrum A an B frame remains the clearest starting point.
Parsing and production checklist
- Identify the two proposed answers, A and B.
- Check that they are grammatically parallel or that any omitted material is recoverable.
- Recognize utrum, -ne, or zero marking before A and an before B.
- Treat an nōn as a negative second alternative, not as an English-style doubled question marker.
- Choose indicative or subjunctive from factual, deliberative, potential, or indirect syntax.
- Answer by naming or repeating an alternative.
Common Mistakes
1. Using ordinary aut inside the correlating utrum frame
❌ Utrum manēs aut abīs?
Poor Classical question framing: aut coordinates alternatives, but utrum normally correlates with interrogative an.
✅ Utrum manēs an abīs?
Are you staying or leaving?
2. Adding a second question marker to the end
❌ Utrum librum an epistulam legisne?
Incorrect: utrum already opens the choice, and final -ne does not mark the whole alternative structure.
✅ Utrum librum an epistulam legis?
Are you reading a book or a letter?
3. Answering without selecting an alternative
❌ —Manēsne an abīs? —Ita.
Unhelpful: ita does not say which of the two alternatives is chosen.
✅ —Manēsne an abīs? —Maneō.
—Are you staying or leaving? —I am staying.
Key Takeaways
Frame alternatives as utrum A an B, A-ne an B, or A an B. When present, the first marker announces a question; an opens the second choice. Use an nōn for a direct “or not,” keep the alternatives parallel, let independent syntax determine mood, and answer by selecting one branch rather than by giving a bare yes or no.
