Comprehensive resource for understanding and mastering English idioms
The idiom "in the loop" means to be aware of something, especially a current situation or development, as it happens. It can also mean being included or involved in a group or activity.
The idiom "in the loop" is believed to have originated from the 1960s when the military began using closed-loop communication systems. These systems allowed for secure and confidential communication between different units, making it difficult for outsiders to intercept or understand the information being exchanged. The term "in the loop" likely emerged as a way to describe someone who was part of this closed-loop system and had access to sensitive information. Over time, the idiom has evolved to refer to anyone who is aware of current events or developments, regardless of their connection to a specific group or activity.
