Design refers to a specification of an object or process, referring to requirements to be satisfied and thus conditions to be met for them to solve a problem. It commonly describes a plan (with more or less detail) for the structure and functions of an artifact, building or system, a pattern, as an element of a work of art or architecture, and the composition of a work of art, which gives the term a broader and more practical sense than a single short definition would suggest. Depending on context, it can also point to intention or plot, the shape or appearance given to an object, especially one that is intended to make it more attractive, and the art of designing, so the category can cover literal uses, related ideas, and more figurative extensions of the same core meaning. Taken together, these meanings present Design as a flexible theme rather than a narrowly technical label, covering the central idea people usually mean when they use the word while still leaving room for closely related senses that appear in real language. Additional shades of meaning include to plan and carry out (a picture, work of art, construction etc.), to plan (to do something), to assign, appoint (something to someone); to designate, to mark out and exhibit; to designate; to indicate; to show; to point out; to appoint, and to manifest requirements to be satisfied by an object or process for them to solve a problem, which reinforce how the category can stretch across adjacent but still recognizable uses of the same term.
