Kaithi is a script used for writing the Hindi language, primarily in the northern regions of India. It is an ancient script that dates back to the 16th century and was commonly used by merchants and traders for record-keeping. The script is characterized by its simple and cursive style, making it easy to write quickly. Although Kaithi was widely used in the past, its popularity has declined with the rise of the Devanagari script, which is now the standard for writing Hindi. Today, Kaithi is mostly of historical interest, with efforts being made to preserve and study this unique script.
