" The noun form of the verb parar is typically used to talk about stops or stations used in public transportation. You can also add a descriptor. For example, "parada de autobús" means "bus stop."

For example: "Su parada excelente ganó el partido." ("His excellent save [stop] won the game.") " If a car or truck is broken down, you might refer to it as "parada," or "stopped." This word can also be used to refer to other types of machinery that are broken or out of service for any reason. For example: "La hélice está parada." ("Our propeller is stopped/jammed.") " Parada is a noun, but parado is an adjective that can also be used to describe something that is stopped or standing still. Since parado changes form to match the gender and number of the noun it modifies, it can also be parada, but it isn't always translated in the same sense. For example, "ha parado de llover" would be translated as "the rain has stopped." But if you said "el portero estaba parado al lado de la portería," that would mean "The goalie was standing next to the goal."
