pysäköityyn

Pysäköityyn is the allative plural form of the Finnish word "pysäköity". In Finnish grammar, the allative case indicates movement towards or to a place, and the plural form refers to multiple instances. Therefore, "pysäköityyn" translates to "to the parked ones" or "into the parked places". This grammatical form would be used in a sentence describing action directed at multiple parked vehicles or multiple parking spots. For example, one might say "Jätin avaimet pysäköityyn autooni" which means "I left the keys in my parked car" (though "pysäköityyn" would typically be used in a context involving more than one car or a more abstract destination). More literally, it could refer to the act of moving something into multiple parking spaces, such as directing multiple vehicles into their designated spots. The specific context of the sentence would determine the precise meaning. It's a locative case ending applied to the past participle of the verb "pysäköidä" (to park).
