Bonsoir Gillian, I believe that your question is about the use of le subjonctif. The subjonctif follows certain phrases and some verbs. The link below is for the Subjunctivisor here on this site: https://www.lawlessfrench.com/subjunctivisor/ It provides which phrases and which verbs require the use of le subjonctif, i.e. bien que, accepter que, etc. I think that you will find this link quite useful, I know that I have. It is a fantastic tool Best regards, Bonne chance,
