Roman capital letters, also known as uppercase letters, are the traditional letters used in the Latin alphabet. They originated from the inscriptions of ancient Rome and were commonly used in official documents, monuments, and public inscriptions. These letters are characterized by their distinct, bold shapes, making them easily recognizable and legible. The Roman capital letters include A, B, C, D, and so on, up to Z. Each letter has a specific form that has influenced modern typography. Today, they are widely used in various contexts, such as titles, headings, and the beginning of sentences, maintaining their importance in written communication.
