However (si... que)

To say "however difficult it may be" or "no matter how steep it is," French uses a specific structure with si.

However... (Si... que)

To express concession like "however [adjective] the [noun] may be," use this formula:

si + adjective + que + subjunctive verb + subject noun

Note these key rules:

  • The adjective agrees with the subject.
  • When the subject is a noun, it typically comes after the verb. The verb is in the subjunctive (usually soit or soient).
However steep the ascent may be, the mountaineer wants to reach the summit.
Si abrupte que soit l'ascension, l'alpiniste veut atteindre le sommet.
However slippery the glacier may be, they are going to cross the crevasse.
Si glissant que soit le glacier, ils vont traverser la crevasse.

If the subject is a pronoun (like il or elle), it comes before the verb:

si + adjective + qu' + pronoun + subjunctive verb

However tired he may be, the mountaineer is going to reach the camp.
Si fatigué qu'il soit, l'alpiniste va atteindre le camp.

Extreme Ascents

When preparing for an extreme ascent (l'ascension), a mountaineer (l'alpiniste) faces perilous (périlleux) cliffs and freezing (glacial) winds.

However perilous the cliff may be, you should climb slowly.
Si périlleuse que soit la falaise, tu devrais grimper lentement.
However freezing the wind may be, we must avoid the avalanche.
Si glacial que soit le vent, nous devons éviter l'avalanche.

You can also use this vocabulary in standard sentences to describe the dangers of the mountain.

You should avoid this crevasse because the snow is slippery.
Vous devriez éviter cette crevasse parce que la neige est glissante.
We did not know where to sleep at this freezing altitude.
Nous ne savions pas où dormir à cette altitude glaciale.
