A person who briefs others, providing them with information or instructions; also a comparative form meaning 'more brief.'
From 'brief' (Old French 'brief', from Latin 'brevis' meaning 'short'). As a noun, it derives from the verb 'to brief,' which emerged in the 20th century in military and governmental contexts.
The word 'briefer' is a double-duty word—it can be both a person AND an adjective describing something shorter, which itself came from Latin 'brevis' where we also get 'abbreviate' and 'bribe' (a brief gift)!
