Answer 2

Answer:

When things captivate or grip you, they're enthralling. You can find another person enthralling, or a well-made movie, a wonderful concert, or an entrancing painting in a museum. Enthralling comes from the verb enthrall, which means "capture one's attention," but had the original meaning of "enslave." The word comes from the prefix en-, "make or put in," and thrall, from the Old English þræl, "serf or slave."
