teismin

Teismin is the genitive singular form of the Finnish noun teismi, meaning theism. It is used to express possession or association with theism in phrases such as teismin opit (theism’s doctrines), teismin kriisi (crisis of theism) or teismin kannatus (support for theism). The base teismi derives from Greek theos through Latin theismus, and in Finnish it denotes belief in a god or gods. In modern Finnish, teismin appears primarily in theological, philosophical, or academic writing and is uncommon in everyday speech, where speakers typically use teismi or broader constructions.

In grammar, teismin is the genitive singular form; other inflected forms follow standard Finnish patterns for -i nouns. The word is mainly encountered in analytic or scholarly contexts when referring to theism as a subject or attribute, rather than in general conversation.

The term is related to other theological and philosophical vocabulary, including teismi, ateismi (atheism), monoteismi (monotheism), and polyteismi (polytheism). It can occur in comparative discussions that examine theism alongside these related beliefs and systems.
