J'ai peur qu'il ne pleuve.I'm afraid it will rain.

That sentence has no pas anywhere, yet a beginner reading only the ne might guess it means "I'm afraid it won't rain" — the opposite of the truth. This lone, meaningless ne is called ne explétif: a leftover formal-register marker that shows up in certain subjunctive clauses and after certain conjunctions, without negating anything at all.

Quick shortcut: after a small set of triggers, a ne with no pas is decorative, not negative — the sentence means exactly the same thing whether it's there or not.

After verbs of fearing and avoiding

Craindre que, avoir peur que, empêcher que and éviter que all take the subjunctive, and in careful writing they often pick up a ne explétif right before the verb:

  • Je crains qu'il ne soit trop tard. (I'm afraid it's too late.)
  • Elle a peur que le vol ne soit annulé. (She's afraid the flight will be cancelled.)
  • Empêchons qu'il ne parte sans nous. (Let's stop him leaving without us.)

Every one of these means exactly the same thing without the ne — Je crains qu'il soit trop tard is just as correct, only a shade less formal.

After avant que, à moins que, de peur/crainte que

The same optional ne turns up after these three subjunctive-triggering conjunctions:

  • *Pars **avant qu'*il ne pleuve. (Leave before it rains.)
  • *Il viendra, **à moins qu'*il ne soit malade. (He'll come, unless he's ill.)
  • *Parle plus bas, **de peur qu'*on ne t'entende. (Speak more quietly, for fear someone hears you.)

After comparatives of inequality

Plus... que, moins... que and similar comparisons of inequality can also take a ne explétif before the second verb, when that second part is a full clause rather than just a noun:

  • Elle est plus intelligente que tu ne le crois. (She's smarter than you think.)
  • C'est moins cher que je ne le pensais. (It's cheaper than I thought.)

Telling it apart from real negation

After one of the triggers above, check whether the clause also has pas or another second negative word (jamais, rien, personne, plus). If not, the ne is the decorative explétif kind, not a negation:

  • Je crains qu'il ne vienne. → "I'm afraid he'll come" — no second negative word, ne explétif.
  • Je crains qu'il ne vienne pas. → "I'm afraid he won't come" — real negation, ordinary ne...pas.

Since it's genuinely optional, dropping ne explétif is never a mistake — only misreading it as negation is.

(Outside this trigger list, very formal/literary French keeps a handful of verbs — oser, cesser, pouvoir, savoir — that can be negated with a bare ne and no pas at all, e.g. Je n'ose le dire. That's a separate, much rarer pattern; it doesn't apply to the triggers taught here.)

Common mistakes

  • ❌ Reading J'ai peur qu'il ne pleuve as "I'm afraid it won't rain" → ✅ it means "I'm afraid it will rain" — after this trigger, a bare ne with no pas isn't negation.
  • ❌ Elle est plus grande que je pense pas. → ✅ Elle est plus grande que je ne le pense. / ✅ Elle est plus grande que je le pense. (the optional ne here isn't negation, so pas can't just be tacked on beside it — pas would only belong for a genuinely different meaning, "she's taller than I don't believe," which isn't what's intended)
  • ❌ Adding ne explétif after an ordinary verb like penser que or dire que, which don't trigger it at all → ✅ Je pense qu'il viendra. (no ne; the trigger list is fixed — fear/avoidance verbs, avant que/à moins que/de peur que, and comparatives)

Quick check

Show answers
  1. What does « Je crains qu'elle ne vienne » mean? → "I'm afraid she'll come" — no negation.
  2. (True or false) Dropping the ne in « avant qu'il ne pleuve » changes the meaning. → False — ne explétif is optional and meaningless.
  3. How would you say "I'm afraid he won't come" in French? → Je crains qu'il ne vienne pas. (real negation pairs ne with a negative word like pas)
  4. Il est plus riche que je ____ (croire). → ne le crois (or, just as correctly, le crois)

Key takeaways

  • Ne explétif is an optional, meaningless ne that can appear after verbs of fearing/avoiding (craindre, avoir peur, empêcher, éviter), after avant que/à moins que/de peur que, and after comparatives of inequality (plus/moins... que).
  • After one of these triggers, it never negates anything on its own — a clause with ne but no second negative word means the plain, positive thing.
  • Real negation pairs ne with a negative word — pas, jamais, rien, personne — so the presence of that second word is what tells the two apart. (A separate, rarer literary pattern lets a handful of verbs — oser, cesser, pouvoir, savoir — drop pas entirely; that's outside this trigger list.)
  • Since it's purely stylistic, leaving ne explétif out is always fine; only misreading it as negation is the actual mistake to avoid.
