sisäosalta
sisäosalta is a Finnish word that translates to "from the inside," "internally," or "on the inside." It is an adverbial form derived from the noun "sisäosa," meaning "inner part" or "interior." The word is used to indicate a location or action occurring within something, as opposed to on the exterior or from the outside.
For example, one might say a building is warm "sisäosalta," meaning it is warm on the inside.
