The prefix AD- indicates which direction?

Explanation:
AD- indicates direction toward something. This prefix comes from Latin ad- meaning toward or to, so it marks movement or position in the direction of the root that follows. In medical terms you’ll see this in examples like adduction, where a limb is brought toward the midline of the body. The opposite directions use different prefixes (ab- for away from, ante- for before, post- for after). So the meaning of AD- is toward.
