totuudelta

Totuudelta is the elative form of the Finnish noun totuus (truth). It denotes origin or source, meaning "from the truth" or "out of truth." It is used chiefly in formal or philosophical prose to indicate that a claim, argument, or idea is grounded in truth or derives its basis from truth. The word highlights how Finnish uses cases to express source; totuudelta can function adjectivally or nominally when describing a statement as totuudelta peräisin or totuudelta pohjaava, though such expressions are relatively uncommon outside scholarly writing.

In translation, totuudelta is typically rendered as "from the truth" or "based on truth," depending on context. The precise interpretation may vary with how "truth" is defined within a given discourse; nuanced discussions of epistemology or rhetoric often foreground interpretations of sources and justification.
