🔶 What is a Highlighter?

A highlighter is a type of writing tool (usually a marker pen) that applies translucent, fluorescent ink over text to make it stand out without obscuring it. It is often used to emphasize or bring attention to important text.

🕰️ History of Highlighters

• 1963 – The first highlighter pen was developed by Dr. Frank Honn and introduced by Carter's Ink Company, later bought by Avery Dennison.

• The original highlighter was called the "Hi-Liter" and used yellow ink (which is still the most popular color).

• Over the years, different colors, tip shapes, and ink types were introduced.

4. Make your own color key (e.g., yellow = key idea, pink = example).
