self-consistent

The word "self-consistent" is a modern English compound adjective, primarily used in logic, philosophy, and science. It is built from the native English prefix "self-," which denotes reflexivity, combined with the adjective "consistent." "Consistent" itself originates from the Latin consistere, meaning "to stand firm, to take a standing position, to be composed of," from con- (together) + sistere (to stand, to place). The literal morphemic idea is "standing together with oneself." Over time, this evolved from the physical notion of stability to the abstract concept of logical harmony and absence of contradiction within a single system or argument. Thus, "self-consistent" describes a state where all elements within a defined framework are in complete agreement, forming an internally stable and non-contradictory unity.
