paráis
Paráis is a Spanish word that primarily functions as a verb form. It is the second-person plural imperative of the verb "parar," meaning to stop, to halt, or to cease. Therefore, "paráis" is used to command a group of people (you all) to stop doing something.
For example, if someone is running and another person wants them to stop, they might shout "¡Paráis!"
The use of "paráis" is specific to the vosotros form of address, which is prevalent in Spain
