A more thorough explanation:

In a legal context, specification refers to providing a detailed statement under a contract regarding quality, measurements, or other important details. For example, a construction contract may include a specification for the type of materials to be used in building a structure.

When it comes to patents, the specification is a section of the patent application that describes how an invention is made, its purpose, and how it should be used or operated. The specification must provide enough information for someone with average knowledge in the field to produce or use the invention as intended by the inventor. For instance, a patent for a new type of computer software would need to include a detailed specification explaining how the software works and how it can be used.

Overall, a specification is a detailed description that outlines important information about a product, service, or invention. It helps ensure that everyone involved in a project or transaction is on the same page and understands what is expected.
