Editor has four major senses:
- a person responsible in some way for the final appearance of a publication;
- a person responsible for the flow of a motion picture or television program from scene to scene
- a person responsible for the flow and choice of music, voice, and other sound material in a recording
- a software tool that can be used to input and format text.
Human editors in the print publishing industry include people who are responsible for:
- obtaining copy or recruiting authors, such as the acquisitions editor for a publishing house
- writing or obtaining material for a section of a newspaper, for example, contributing editor, book reviews editor, travel editor
- organizing and publishing a magazine — an editor-in-chief
- organizing and managing contributions to a multi-author book, for example, a symposium editor
- producing a definitive edition of a classic author's works — a scholarly editor
- improving an author's writing so that they indeed say what they want to say, in an effective manner — substantive editor. Depending on the writer's skill, this editing can sometimes turn into ghost writing[?].
- correcting spelling, grammar, and matters of house style — a copy editor
- choosing the layout of the publication and communicating with the printer — a production editor
- functioning like the guy who follows the elephants in a parade — a Wikipedia editor
The smaller the publication, the more these roles run together. In particular, the substantive editor and copy editor often overlap:
- fact checking can be the responsibility of either
- the copy editor who finds an infelicitous phrase will often suggest an improvement
In the film industry the editors play a dynamic and creative role in splicing separate takes into a coherent film. It is not a simple matter of tacking the scene inside the house on after the scene of the man walking up to the front door.
In radio, film, and television, the sound editor has a major decision-making and creative role.
Editors are also software tools, including HTML editors, text editors, and graphics editors[?]. More complex text-producing tools with WYSIWYG interfaces are generally referred to as word processors.
According to the Oxford English Dictionary, editor comes from the Latin phrase e ditus which means "to put forward". The editor ludorum in Ancient Rome was the person who put on the games. In French, editeur means "publisher". The word came into English from French.
The verb edit is a back formation from editor.
