What is Corporate Jargon?

Legal Definition
Corporate jargon, variously known as corporate speak, corporate lingo, business speak, business jargon, management speak, workplace jargon, or commercialese, is the jargon often used in large corporations, bureaucracies, and similar workplaces.

The tone is associated with managers of large corporations, business management consultants, and occasionally government. Reference to such jargon is typically derogatory, implying the use of long, complicated, or obscure words, abbreviations, euphemisms, and acronyms. For that reason some of its forms may be considered as an argot. Some of these words may be actually new inventions, designed purely to fit the specialized meaning of a situation or even to "spin" negative situations as positive situations.

Marketing speak is a related label for wording styles used to promote a product or service to a wide audience by seeking to create the impression that the vendors of the service possess a high level of sophistication, skill, and technical knowledge. Such language is often used in marketing press releases, advertising copy, and prepared statements read by executives and politicians.
