Latin Fearing Clauses: timeo ne, timeo ut and ne non

By Michael McGettrickUpdated 12 October 2026

After a verb of fearing, means that and means that not. is I am afraid that he/she will come. That is the reverse of what every other and has taught you, and it catches almost every learner the first time.

Quick check

Three quick questions on what you have just read. The full practice is further down.

Pick the right one

0/3

Tap the subjunctive. Is the fear present or past? About later, or about something already done?

  1. I am afraid that the king will come: Timeo ne rex .

  2. I was afraid that the king would come: Timebam ne rex .

  3. I am afraid that the king has fled: Timeo ne rex .

After timeoLatinEnglish
.I am afraid that he/she will come.
.I am afraid that he/she will not come.
.I am afraid that he/she will not come.
infinitive .I am afraid to come.
accusative .I am afraid of him.

The first three lines are the fearing clause proper. The last two are the other things a fear verb can take, further down the page.

Fearing clauses introduced by and are on the OCR GCSE Latin prescribed syntax list.

Why ne means that

ne: that it will happenut, ne non: that it will notWhat do the colours mean?

It is not perverse once you see where it came from. A fearing clause began as two thoughts side by side: a fear, and a wish about the thing feared.

OnceEnglishNow
. !I am afraid. May he/she not come! .
. !I am afraid. May he/she come! .

is the ordinary negative of a wish: , may he/she not come. Wishing that someone will not come is the same as fearing that they will. Fuse the two thoughts and English turns the wish inside out: I am afraid that he/she will come.

The front of a Roman house with a red-tiled roof, round windows and potted plants; a white doorway with columns and a pediment stands open, an orange door swung inward. On the threshold in front lies a tiled mosaic with a red-tiled border, showing a black dog with a red collar in the Pompeii cave canem style.
  1. mordeat.

A cave canem mosaic, beware of the dog, guards the door. The visitor's thought is a fearing clause: timeo ne canis mordeat, I am afraid that the dog will bite (once: I am afraid. May the dog not bite!).

So do not translate the at all. Read as one unit, I am afraid that, and the clause after it as the thing feared.

ut or ne non?

ut, ne non: that it will notWhat do the colours mean?

Both mean that not. The difference is habit, not meaning.

FormWhere you meet it
comedy and Cicero; the short form
most prose; regular when the fear itself is negated
  • . - I am not afraid that he/she will not come.
  • . - I am afraid that the leader will not come back.

The need not sit beside the . And the two do not cancel out: read ... as that ... not, never as a double negative.

The words of fearing

LatinMeaningExample
be afraid, fear .
metuofear, dreadMetuo .
vereorfear ()Vereor .
there is fear .
there is a danger .

The nouns work just like the verbs: there was a fear that the enemy would come; there is a danger that the city will be captured. Vereor is , so it looks passive and means I am afraid.

Tenses: the sequence again

ne: that it will happenthe tense signWhat do the colours mean?

A fearing clause follows the sequence of tenses. The left column fears what may come; the right column fears what may already have happened.

FearAbout now or laterAbout the past
present
past
  • . - I am afraid that he/she has come.
  • . - I was afraid that he/she would come.
  • . - I was afraid that he/she had come.

A fear about the future needs no -urus participle, unlike an indirect question: the present and imperfect subjunctive already face forward, because a fear is by nature about what might come.

Fear with an infinitive, fear with a noun

ne: that it will happeninfinitive: afraid toaccusativedativeWhat do the colours mean?
ConstructionLatinEnglish
+ infinitive .I am afraid to go out.
+ clause .I am afraid that he/she will go out.
+ accusative .I am afraid of the enemy.
+ dative .I am afraid for you.

With an infinitive the fear stops you doing something yourself; with the feared thing is an event, often someone else's. English draws the same line with afraid to and afraid that. The angel's words to Joseph use the infinitive:

Ioseph David, Mariam coniugem .

Joseph, son of David, do not be afraid to take Mary as your wife. (Matthew 1:20, Vulgate)

And the most quoted fear in Latin takes a plain accusative. Laocoon, on the wooden horse:

, Danaos .

Whatever it is, I fear the Greeks, even when they bring gifts. (Virgil, Aeneid 2.49)

ne in three jobs, side by side

ne: that it will happenWhat do the colours mean?

Fearing clauses share with two constructions where it really does mean not. Sort every by the main verb before you translate it.

Main verbLatinne means
a fear .that
an action .so that not
asking .not to

The first two are the same clause after different verbs: he/she was afraid that he/she would be captured against he/she fled so as not to be captured.

Reading one: a worked example

, , .

  1. Main verb , a fear, past: expect = that and an imperfect or pluperfect subjunctive.
  2. ... : cum with the pluperfect subjunctive, when they had heard; inside it, is an indirect statement.
  3. : imperfect subjunctive passive, a fear about the future from a past viewpoint.

When the citizens had heard that the enemy were coming, they were afraid that the city would be captured.

The classic trap, and its relatives

WrongRightWhy
: won’t comethat he/she will comeAfter a fear, means that
: so thatthat he/she will not comeAfter a fear, means that not
: cancels outthat he/she will not come ... means that not
A past fear takes the imperfect
: thatI am afraid to go outThe infinitive means afraid to

If you are unsure which you are looking at, go back to the three jobs: the main verb decides.

What to do next

  1. Learn and as a fixed pair.
  2. Write the four tenses with and .
  3. Then go back over purpose clauses and indirect commands, and sort every you find into its three jobs.

Frequently asked questions

Why does mean that after ?
Because a fearing clause began life as a wish beside a fear. was once two thoughts: I am afraid; may he not come! is the ordinary negative of a wish, and the thing wished away is the thing feared. English turns the whole into I am afraid that he/she will come, so the disappears. Translate as not here and you reverse the sentence.
What is the difference between and ?
None in meaning: both are I am afraid that it will not happen. is the shorter form, found in comedy and in Cicero; is commoner in most prose and is the regular form when the fear itself is negative, as in , I am not afraid that he/she will not come. Read both as that not.
What is the difference between and ?
, with an infinitive, means I am afraid to go out: the fear stops you doing it yourself. , with and the subjunctive, means I am afraid that he/she will go out: the feared thing is an event. English draws the same line with afraid to and afraid that.
Which tenses are used in a Latin fearing clause?
The sequence of tenses. After a present fear, the present subjunctive is a fear about now or later ( , I am afraid he/she will come) and the perfect a fear about the past ( , I am afraid he/she has come). After a past fear, use the imperfect ( , I was afraid he/she would come) and the pluperfect ( , I was afraid he/she had come). No -urus participle is needed: the present and imperfect already look forward.
What does Danaos mean?
I fear the Greeks, even when they bring gifts. Laocoon says it in Virgil's Aeneid (2.49) about the wooden horse; Virgil wrote , an older spelling of the accusative plural. It is a fear verb with a plain accusative object, no clause at all: , I am afraid of the enemy.
