Etymology

The word 'delimiter' is derived from the root word 'limit', which comes from the Latin 'limitem', meaning boundary or limit. However, the specific term 'delimiter' emerged in the field of computer science and data management in the mid-20th century, as systems began to require methods to distinctly segment data for effective processing and representation. The use of delimiters became especially prevalent with the rise of programming languages and data formats that required structured ways to interpret information. As data exchange became more common between different systems, the standardized use of delimiters in formats like CSV, XML, and JSON highlighted their importance in ensuring correct data parsing and retrieval.
