As a noun, a highlight is the best or most exciting part of something. As a verb, to highlight means to stress, mark, or draw attention to something as important.
Originally an art term from “high” + “light,” meaning the brightest area in a painting that shows where light hits. It later took on the figurative sense of the “brightest” or best part of an event or text.
When you highlight text, you’re literally recreating what painters did—pulling out the bright spots so the eye goes there first. The word turned a visual trick into a mental one: highlights now mark not just what shines, but what matters. Your brain ends up remembering the “highlights reel” of your life more than the full video.
