epäloogiseen

epäloogiseen is a Finnish illative form of the adjective epälooginen, meaning illogical or not logical. The base word epälooginen is formed with the prefix epä- meaning “not” or “un-” added to looginen (logical). The illative form appears when the adjective modifies a noun in the illative case, indicating movement toward or into a state or target of action.

In usage, epälooginen describes reasoning, statements, or conclusions that lack logical coherence, are internally inconsistent, or rely on fallacies. Finnish adjectives agree with the noun they modify in number and case, so epälooginen becomes epäloogiseen when the noun is in illative singular, for example: epäloogiseen väitteeseen (to an illogical claim) or epäloogiseen johtopäätökseen (to an illogical conclusion). The illative form is common in analytical writing, journalism, and everyday speech when critiquing reasoning.

The term can appear predicatively or attributively. Predicative: Tämä väite on epälooginen. Attributive: epälooginen väite. It is often contrasted with looginen (logical) and discussed within the broader field of logic and reasoning. While closely related to concepts of irrationality or absurdity, epälooginen specifically targets coherence and valid logical structure in arguments.
