If n'est pas le seul mot pour exprimer une condition. Voici les plus utiles, avec leur sens exact.

MotSensExemple
unlessà moins que, sauf si (= if ... not)I'll go unless it rains. (= if it doesn't rain)
provided (that) / providingà condition que (condition stricte)You can go out provided that you're back by ten.
as long asdu moment que, tant queYou can borrow it as long as you take care of it.
in caseau cas où (précaution)Take an umbrella in case it rains.
otherwise / or elsesinonHurry up, otherwise we'll be late.
even ifmême siI'll go even if it rains.

Le temps après ces mots

Comme après if, on n'utilise pas will après unless, provided that, as long as, in case : on met le présent.

I'll call you unless I'm busy. (et non unless I'll be)
Je t'appellerai sauf si je suis occupé.

Attention : unless contient déjà la négation. On dit unless you hurry, et non unless you don't hurry.

Ne confondez pas : Take a coat in case it gets cold (au cas où, par précaution) et Wear a coat if it gets cold (seulement s'il fait froid).

Mise en situation : une soirée à négocier

Noah : Mum, can I go to Tom's party on Saturday?
Maman, je peux aller à la soirée de Tom samedi ?
Mum : Yes, provided that you're home by midnight.
Oui, à condition que tu sois rentré avant minuit.
Noah : Midnight? Unless Dad picks me up, I'll have to leave at eleven!
Minuit ? À moins que Papa vienne me chercher, je devrai partir à onze heures !
Mum : Fine, he'll pick you up, as long as you text us. And take a jacket in case it gets cold.
D'accord, il viendra te chercher, du moment que tu nous envoies un message. Et prends une veste au cas où il ferait froid.

À retenir

  • unless = if ... not (sans autre négation).
  • provided that / as long as = à condition que ; in case = au cas où ; otherwise = sinon.
  • Pas de will après ces mots : présent.
  • in case (précaution) ≠ if (condition).
