Let's break down the phrase:
* Venez: This is the imperative form of the verb "venir" (to come). It means "come" in this context.
* à la maison: This translates to "home" or "to the house".
* papa: This is the French word for "dad".
* maintenant: This means "now".
So, the sentence is a direct command to the father, telling him to come home immediately.
