proceedings
The official actions and events of a formal meeting or case.
Proceedings are the events and activities that happen during a formal meeting, legal case, or official ceremony. When a judge opens court proceedings, she's starting the official business of hearing a case. When minutes record the proceedings of a student council meeting, they document what was discussed and decided.
The word suggests something more organized than a casual conversation. A birthday party has events, but a town hall meeting has proceedings. There's usually an order to follow, rules about who can speak, and often someone keeping an official record.
In legal contexts, proceedings can mean the entire process of a court case, from the first filing through the final judgment. A lawyer might say “the proceedings lasted three weeks” to describe how long a trial took.
You'll also see this word in published collections from academic conferences, where proceedings means the written papers and discussions from the event. Scientists share their proceedings so others can learn what was discovered and debated.
