Borrowed from Latin cōnsistēntem, present participle of cōnsistō (“to agree with; to continue”), from con- (prefix indicating a being or bringing together of several objects) (ultimately from Proto-Indo-European ḱóm (“beside, by, near, with”)) + sistō (“to cause to stand; to place, set”) (ultimately from Proto-Indo-European stísteh₂ti (“to be standing up; to be getting up”), from the root *steh₂- (“to stand (up)”)).
Often followed by the preposition 'with' when comparing two things for agreement.
