Domain-specific language

A domain-specific language (DSL) is a type of programming language that is used to make it easier to solve a particular kind of problem. It's like giving a special set of instructions to the computer that only apply to the problem you're trying to solve. Just like using regular language, which is best when talking to people, DSL is designed to be best when talking to computers. For example, instead of typing out a long list of instructions for a computer to find what you're looking for in a database, you could use a DSL to do it for you. With a DSL, the computer would be able to quickly understand what you want and do it for you.
