In two parts; paired.
Greek dikho‑, apart, in two.
The most common example of this rather rare form is dichotomy (Greek ‑tomia, cutting), a contrast between two things that are opposed or entirely different; others are dichogamy (Greek gamos, marriage), referring to the ripening of the stamens and pistils of a flower at different times, so that the flower cannot fertilize itself; and dichotic (Greek ous, ōt‑, ear), involving or relating to the simultaneous stimulation of the right and left ear by different sounds.
