Using the Present Subjunctive in Certain Relative Clauses

The subjunctive is also used in relative clauses when the antecedent, or the noun or pronoun to which the relative clause refers, is indefinite. Another way of stating this is to say that the subjunctive is used in relative clauses in which the noun or pronoun to which the relative clause refers has not yet been identified, or is not known.

A few common expressions that typically precede these clauses include: Y a-t-il quelqu'un qui...?, Connaissez-vous quelqu'un qui...?, Je cherche quelqu'un qui..., and Il n'y a personne qui...

Listen to the following sentences:

Je cherche une maison qui ne soit pas chère.
I am looking for a house that is not expensive. (You haven't located one yet.)
Connaissez-vous quelqu'un qui sache réparer ma voiture?
Do you know someone who can fix my car?
J'ai besoin d'un médecin qui puisse guérir son cancer.
I need a doctor who can cure his cancer.

Using the subjunctive after a superlative construction, or following le dernier, le premier, or le seul.

Marie est la plus belle fille que je connaisse.
Marie is the most beautiful girl I know. (This is your opinion and not a fact.)
