Subjunctive After Superlatives and Unique Expressions
The French subjunctive appears after superlative adjectives (le plus grand, le meilleur) and unique or restrictive expressions (le seul, le premier, le dernier). These expressions convey a speaker's judgment that something is the most extreme or the only one of its kind, which triggers subjunctive mood in the dependent clause.
Subjunctive follows superlatives (le plus, le meilleur, le seul, le premier) because they express a subjective judgment rather than an objective fact. The speaker is evaluating, not stating certainty.
Step-by-step worked examples
C'est le film le plus intéressant que j'aie jamais vu. (It is the most interesting film I have ever seen.)
Superlative: le plus intéressant (the most interesting) Subjunctive trigger: judgment, not fact Subjunctive clause: que j'aie jamais vu (past subjunctive, that I have ever seen)
Elle est la seule personne qui puisse résoudre ce problème. (She is the only person who can solve this problem.)
Unique expression: la seule (the only) Subjunctive trigger: restriction/uniqueness Subjunctive clause: qui puisse résoudre (present subjunctive, who can solve)
C'est le premier livre qu'il ait écrit. (It is the first book he has written.)
Superlative/ordinal: le premier (the first) Subjunctive trigger: ordinal/ranking judgment Subjunctive clause: qu'il ait écrit (past subjunctive, that he has written)

FAQ
What is the difference between superlative and comparative?
Comparative (plus, moins, aussi) compares two things → indicative. Superlative (le plus, le seul, le premier) ranks the most extreme → subjunctive.
Does 'le premier' always trigger subjunctive?
Yes. Le premier (the first), le dernier (the last), and le seul (the only) all express a unique ranking → subjunctive in the dependent clause.
Can you use past subjunctive with a present superlative?
Yes. If you're talking about something that already happened, use past subjunctive: C'est le meilleur film que j'aie vu (the best film I have seen so far).
What if the subject of superlative clause is the same?
If the subjects differ, you need subjunctive: C'est le meilleur film qu'il ait vu. If the same, you typically still use subjunctive: C'est le meilleur film que j'aie vu.
