In 22.8, in the section Why is it in the Subjunctive? we are given two sentences (both correct):
(i) Je cherche une personne qui sait parler anglais.   
(ii) Je cherche une personne qui sache parler anglais.

Both mean "I seek a person who can speak English."  However there is a subtle difference.
The explanation given is:  "The difference between the sentence in the subjunctive and indicative is the fact you are not too sure whether such a person exists."
But it doesn't say which sentence this applies to!
I assume that the indicative is used when you know the person exists, and the subjunctive is used when there is doubt. Would that be correct? 

 

Salut Peter--252 !

Yes, you've got that right: the subjunctive is often used to reflect doubt, so the sentence in the subjunctive (Je cherche une personne qui sache parler anglais) would be the one where you are not sure whether such a person can be found. 

I'll pass a note on to the development team and see if they can make the wording more precise here.

Thank you for your feedback, and our apologies for the confusion!

À la prochaine,
