seinämissään

seinämissään is a Finnish word. It is the inessive plural form of the word seinä, which means "wall". The inessive case in Finnish indicates that something is located inside or within something else. Therefore, "seinämissään" translates to "in its walls" or "within its walls".

This word is used to describe a location or state that is contained by multiple walls. For example, one might say that a historical building has many stories seinämissään, meaning that the building's walls hold the history within them. Similarly, a person might feel trapped seinämissään, implying they feel confined by their surroundings or circumstances, which are metaphorically represented as walls. The plural form suggests that there are multiple enclosing boundaries, emphasizing a sense of enclosure or containment. The possessive suffix "ään" indicates that these walls belong to a singular entity, referring back to the subject of the sentence.
