The subjunctive is always preceded by que/ qui and almost always in a dependent clause. However, these two factors can be present without the subjunctive being required, so how do we know? The first indicator is the main clause.The subjunctive is used for the subjective and uncertain, so if the main clause expresses desire, possibility, feelings, obligation, judgement or advice, the subjunctive is required.Nota Bene: If the main clause contains a verb such as croire, penser, trouver, être certain/sûr que, or espérer, the subjunctive is only used if the verb is negative, if the verb is positive the indicative is used (if the subject believes or hopes that something is true they will speak of it as if it is). In some cases, specific conjunctions or expressions require the subjunctive. Conjunctions of Time or conjunctions introducing a hypothetical situation or a condition, and indefinite expressions or expressions referring to the peerless status of someone or something (meilleur, premier,…) always take the subjunctive.
