Learn French: Nous emportons nos billets parce que nous partons. - We are taking our tickets because we are leaving.

Partir (to leave) is an irregular -ir verb. Unlike regular -ir verbs that add an -iss- sound in the plural (like nous finissons), verbs like partir, sortir, and dormir skip it. For nous, you just drop the -ir and add -ons, giving us nous partons.

Why use emportons for 'taking'? Couldn't we use prenons (from prendre)?

You could, but emporter is much better here! While prendre means 'to take' in a general sense, emporter specifically means 'to take along' or 'to take with you' when you leave a place.

Why is it nos billets instead of notre billets?

In French, possessive words like 'our' have to match the noun they describe. Because billets (tickets) is plural, you must use the plural form nos. If you only had one ticket, it would be notre billet.

Do I pronounce the 's' at the end of nous in nous emportons?
