yläreunastaan

yläreunastaan is a Finnish word that literally translates to "from its upper edge" or "at its top edge." It functions as an adverbial postposition, indicating location or origin in relation to the uppermost part of something. The word is formed by combining "ylä-" (upper), "reuna" (edge/border), and the possessive suffix "-nsa" (its), with the adessive case ending "-sta" (from/at). The adessive case in Finnish often denotes location or presence, and in this context, it specifies the origin or point of reference as being the top edge.

For example, one might say that a stain is visible yläreunastaan on the wall, meaning the stain is visible at the upper edge of the wall. Similarly, a crack could appear yläreunastaan in a piece of wood. The usage is quite specific, focusing on the very top boundary or rim of an object or surface. It is a descriptive term, helping to pinpoint a particular area of concern or observation. The grammatical structure of yläreunastaan highlights its function as a locative indicator.
