a romantic is a person who believes in romanticism, which is like a philosophy on life. Romantics love nature, old things like castles and churches, love poetry and beauty, and have a tendency to get carried away by ideas. This can be both bad and good, as most of the original romantics stood up for their beliefs and greatly helped England, but also went to help people in revolutions and got killed. They also tend to get randomly depressed, but this is because the weather and colors and beatiful things make them act differently than others.
Lord Byron was the greatest romantic who will ever live.
