What does highlighter mean?
A highlighter is a pen that uses vivid, often fluorescent ink to mark important words or passages in printed or handwritten text. It is especially associated with studying, editing, and office work, where it helps readers identify important material quickly. The word can also be used figuratively for a person or thing that stands out, such as a leading performer, a notable achievement, or the most memorable feature of an event. In that broader use, “highlighter” suggests someone or something singled out for attention, recognition, or praise. Although the meaning is usually neutral, the figurative sense can sometimes sound promotional or retrospective, depending on the context. The term is common in both British and American English, and its bright, practical associations make it a familiar part of modern educational and media vocabulary.

Etymology of highlighter
The word combines “high” and “light,” reflecting the original sense of making text or passages stand out by covering them with bright colour. “Highlight” developed in the early 19th century in contexts involving drawing attention to something, and “highlighter” later referred to the tool used for that purpose. The element “light” connects the word with related forms such as “lighthouse” and “delight,” although “highlighter” itself is an English compound and derivative.
