sisältämästään

sisältämästään is a Finnish grammatical form. It is the elative case of the third infinitive of the verb "sisältää". "Sisältää" means "to contain" or "to include". The elative case in Finnish often translates to "from" or "out of" in English, indicating origin or separation. Therefore, "sisältämästään" essentially means "from what it contained" or "from that which it contained".

This form is used when referring to something that has been taken out of or separated from something else that it previously contained. For example, "Hän poisti sen säiliöstä sisältämästään" would translate to "He removed it from the container from that which it contained" or more naturally, "He removed it from the container that contained it." The "-stään" ending specifically refers back to the subject performing the action, implying that the subject itself contained something.

The construction can also be used in a more abstract sense, referring to an idea or concept that was part of a larger whole. For instance, "Ajatus erottui hänen puheestaan sisältämästään todellisuudesta" could mean "The idea stood out from his speech from the reality it contained," implying the idea was extracted from the reality presented in the speech. Understanding the case and the infinitive form is crucial for correctly interpreting the meaning of "sisältämästään" in Finnish sentences.
