Epäyhdenmukainen

Epäyhdenmukainen is a Finnish adjective meaning not in accordance or not in agreement with something else. It is formed from the negation prefix epä- attached to yhdenmukainen, which denotes conformity, consistency, or congruence. The term is used to describe things that do not match, conflict with, or fail to be compatible with a reference point such as facts, data, or other statements.

In usage, epäyhdenmukainen can refer to statements, measurements, or observations that contradict each other or do not fit a model. It is common in scientific and analytical writing to describe data as epäyhdenmukaisia if results diverge from expectations. In logic or argumentation, it may denote reasoning that is inconsistent with given premises. In geometry, the term can describe figures or shapes that are not congruent or do not share the same size and shape as another reference figure.

Nuances of meaning include a sense of logical or factual mismatch rather than mere error. While often translated as inconsistent, it can also imply a lack of compatibility or coherence with a broader framework. Related Finnish terms include ristiriitainen (contradictory) and epäjohdonmukainen (illogical or inconsistent).
