Y and En

Y is used instead of à or de, and goes in front of the verb - like the common phrase you will know 'il y a' - there areHow might you use this?If someone said - Avez-vous visité Madrid? Instead of repyling "Ma famille et moi passons les vacances à Madrid" you could replace 'à Madrid' with 'y'. So... "Ma famille et moi (nous) y passons les vacances" Therefore 'y' is say 'there', "We spend the holidays there" Y is also used instead of à + infinitive eg: penser à or s'attendre à. So, in the sentence "Mon frère attend  à me voir devenir végétarien" if you wanted to say, "He is waiting for it" (it being you becoming veggie), you could use 'y' and say "Il s'y attend"En replaces du/de la/ de l'/ des + noun. En can mean then... some, any, of it, or of themEn goes before the verb, and when used with the perfect tense, as is the case with on, it must go before the auxilary (avoir or etre)Take the question: "Faites vous du sport?" Instead of repeating the noun (sport) + du, we can use en... So the response would be "Oui j'en fais" instead of "Oui, je fais du sport" If verbs are followed by de, then we can use en to say 'of it/ about it' etc, so "Nous en rions" for instance, would mean "We laugh about it"
