Classical Latin normally negates a command with nē, not with statement negator nōn. A compact prohibition addressed to one person is nē hoc fēcerīs “do not do this”; a negative jussive about someone else is nē intrent “let them not enter.” The subjunctive presents an action as something the speaker wills not to occur.
This particle is a separate word with a long vowel in pedagogical spelling. It must not be confused with interrogative enclitic -ne, attached to another word: venitne? “is he coming?” versus nē veniat! “let him not come!” English uses “do not” for several kinds of directive, but Latin distinguishes the addressee and the construction more explicitly.
The core command patterns
| Person addressed or controlled | Productive Classical pattern | Example |
|---|---|---|
| one “you” | nē
| nē fēcerīs |
| several “you” | nē
| nē fēcerītis |
| “let us not” | nē
| nē abeāmus |
| “let him/her/them not” | nē
| nē discedat / discedant |
Nē arcānum cuiquam patefēcerīs.
Do not reveal the secret to anyone.
Discipulī, nē hās litterās mīserītis.
Students, do not send these letters.
Nē spem relinquāmus, quamquam rēs difficilis est.
Let us not abandon hope, although the situation is difficult.
Nē quis ante lūcem castra relinquat.
Let no one leave the camp before dawn.
The perfect subjunctive in second-person prohibitions points forward in function even though it is morphologically “perfect.” It commonly packages the forbidden act as a bounded occurrence that must not happen. The present subjunctive is central in first- and third-person negative directives. Second-person nē plus present subjunctive also occurs, especially in general advice, early Latin, and verse (literary/poetic), but nē + perfect subjunctive and nōlī/nōlīte + infinitive are dependable Classical prose models.
Forming the second-person perfect
Build an active perfect subjunctive from the third principal part. Remove final -ī and add -erīs for one addressee or -erītis for several.
| Principal part | One addressee | Several addressees |
|---|---|---|
| dīxī | nē dīxerīs | nē dīxerītis |
| dūxī | nē dūxerīs | nē dūxerītis |
| scrīpsī | nē scrīpserīs | nē scrīpserītis |
| cēpī | nē cēperīs | nē cēperītis |
Nē equōs per viam angustam dūxerīs.
Do not lead the horses along the narrow road.
Nē quid temere dīxerītis.
Do not say anything rashly, all of you.
Without macrons, dixeris could formally be a perfect subjunctive or a future perfect indicative. Construction decides: independent nē dīxerīs performs a prohibition, whereas cum hoc dīxeris, discede “when you have said this, leave” puts a future-perfect event before a future command. The full ambiguity is explained under Future Perfect and Perfect Subjunctive Homonymy.
Nē, nōn, and -ne perform different jobs
The spelling difference encodes three structures:
| Form | Job | Example |
|---|---|---|
| nōn | denies a statement or constituent | nōn venit, “he is not coming” |
| nē | negates a directive and several dependent clause types | nē veniat, “let him not come” |
| -ne | marks a yes–no question | venitne?, “is he coming?” |
Mārcus nōn clāmat.
Marcus is not shouting. (statement)
Nē Mārcus clāmet.
Marcus must not shout; let Marcus not shout. (negative jussive)
Clāmatne Mārcus?
Is Marcus shouting? (question)
Intonation cannot replace these visible distinctions in careful written Latin. Nor does the subjunctive by itself mean “do not”: a particle, person, independent-clause setting, and directive context jointly produce the negative command.
Nōlī and nōlīte as an alternative
For a command addressed directly to “you,” Classical Latin also uses nōlī (singular) or nōlīte (plural) plus a present infinitive. These are imperatives of nōlō “be unwilling,” conventionalized as prohibitions.
Nōlī hanc ollam tangere; calida est.
Do not touch this pot; it is hot. (one addressee)
Nōlīte sine duce in silvam intrāre.
Do not enter the forest without a guide. (several addressees)
Both nōlī tangere and nē tetigerīs can mean “do not touch.” The first displays the addressee's number on nōlī/nōlīte and names the forbidden act with an infinitive. The second displays number on the perfect subjunctive. Context and authorial preference matter more than any rigid polite-versus-rude scale. See Negative Commands with Nōlī and Nōlīte for that pattern in full.
Negative commands inside a larger sentence
When a verb of ordering, warning, begging, or persuading reports a negative command, nē + subjunctive introduces the command's content. Its tense follows sequence, rather than mechanically copying the independent perfect-subjunctive prohibition.
Māter fīlium monet nē sōlus proficīscātur.
The mother warns her son not to set out alone.
Māter fīlium monuit nē sōlus proficīscerētur.
The mother warned her son not to set out alone.
Present proficīscātur follows primary monet; imperfect proficīscerētur follows historic monuit. The negative directive explains nē. A factual report “she says that he is not setting out” would require a different indirect-discourse structure with nōn.
Period and register
The system above is the productive (neutral to formal) Classical prose baseline. Early Latin and poetry can put nē before a present imperative, a pattern avoided as a general prose model. Virgil writes:
tu ne cede malis
Do not yield to misfortunes. — Virgil, Aeneid 6.95 (literary excerpt; source spelling reproduced)
Here nē cēde in normalized pedagogical spelling combines nē with a present imperative. The verse is excellent Latin but intentionally not the default pattern an A2 learner should generalize to every verb. Later Latin expands and redistributes several prohibitive patterns (later Latin); the core contrast between statement nōn and directive nē remains fundamental.
Common Mistakes
1. Using statement nōn as English “do not”
❌ Nōn currite per viam.
Not the ordinary Classical prose construction for a prohibition to several people.
✅ Nōlīte per viam currere.
Do not run through the street.
2. Translating a perfect prohibition as past
❌ Nē hoc scrīpserīs = ‘You have not written this.’
Incorrect — in this independent directive the perfect subjunctive prohibits a future act.
✅ Nē hoc scrīpserīs = ‘Do not write this.’
The construction, not the tense label alone, determines the force.
3. Separating interrogative -ne
❌ Venit nē Quīntus?
Incorrect for ‘Is Quintus coming?’ — interrogative -ne is an enclitic.
✅ Venitne Quīntus?
Is Quintus coming?
4. Blending two prohibitive patterns
❌ Nōlī nē iānuam aperīre.
Incorrect — nōlī already governs the forbidden infinitive directly.
✅ Nōlī iānuam aperīre.
Do not open the door.
Key Takeaways
The essential choice is functional: use nōn to deny, nē to forbid, and attached -ne to ask. Within prohibition, match person and number, then choose either the relevant jussive subjunctive or the intact nōlī/nōlīte + infinitive construction.
