syistä

Syistä is a Finnish noun form meaning “from the reasons” or “for reasons.” It is the plural elative form of syy, which means reason or cause. The elative plural ending -istä/-istä indicates origin or basis, and syistä is used when discussing multiple causes or explanations.

In usage, syistä appears in phrases that refer to several underlying factors. Common constructions include useista syistä (for several reasons) and monista syistä (for many reasons). A frequent expression is useista syistä johtuen, meaning “due to several reasons” or “for reasons of several causes.” Although syistä often appears with other words, it functions as a plural noun form that marks provenance or justification in causal contexts.

Morphologically, syy declines through cases, with syistä serving as the plural elative form. This contrasts with syitä, the partitive plural, which has a different grammatical function. Practically, syistä is most visible in written and formal Finnish when enumerating or explaining multiple causes.

In summary, syistä is the plural elative of syy used to express origin or justification of multiple reasons, and it appears in phrases that discuss several causes or explanations.
