Jargon

Jargon refers to words or expressions used by a particular group that are difficult for others to understand. The world of English teaching is by no means immune to the use of both jargon and acronyms.

Examples:

 * management-speak, corporate-speak, marketing-speak, geek-speak, lawyer-speak, media-speak, government-speak, military-speak, computer-speak, BBC-speak, tech-speak, legal-speak.
