Which prefix indicates movement towards something?

  1. Aniso-

  2. Ad-

  3. Anti-

  4. Ab-

The correct answer is: Ad-

The prefix that indicates movement towards something is "Ad-." This prefix is derived from Latin, where it means "to" or "toward." Its usage implies a direction or movement in the vicinity of or into a particular place, making it appropriate for describing something that is approaching or moving towards another entity. In contrast, "Aniso-" typically refers to inequality or dissimilarity and does not convey movement in any direction. "Anti-" denotes opposition or contrast, suggesting a movement against something rather than towards it. "Ab-" signifies movement away from something, further establishing a separation rather than an approach. Thus, "Ad-" clearly aligns with the concept of movement towards an object or location.
