The term 'providing essential information' can be summarized by the 8-letter word 'BRIEFING'. A BRIEFING is a short, concise summary of important information that is provided to someone. It is typically used to provide an overview of a particular topic or situation, and can be used in a variety of contexts, such as business meetings, military operations, and educational settings. Briefings are often used to ensure that everyone involved has the same understanding of the situation and can make informed decisions.
