Depending on whether you're talking about the subject or the object of the sentence, that's when you need to choose either 'qui' or 'que'.Just to recap, the subject is the thing doing the action, and the object is the thing having the action done to it. You'll use 'qui' when talking about the subject, and 'que' for the object. For example:"Je cherche quelqu'un qui parle anglais."Here, you're looking for someone who speaks English. That person is the subject as they will be the one speaking, so you'll use 'qui'."J'ai lu le livre que tu m'as donné."In this case, you're talking about the book that your friend has given to you. Because the book had an action done to it, it becomes the object, and so you'll use 'que'."Je vais prendre le train. Il va a Paris."Would I use qui or que here to make this one sentence? Why?
